sarge1130- Don't you just love those goofballs? XD

Onwards!

"Room." Law said, holding his hand up as the customary disc of blue energy began to form beneath his palm. Lexi watched as it expanded across the bedroom and came to a stop at the edge of the wall, enclosing the both of them inside. Arms crossed, the brunette quirked a brow in his direction as he took out his own heart with the 'Mes' technique. The sight no longer came as a shock to her, seeing as he'd done the very same thing to her several times before.

"Are you sure that's necessary?" She inquired, swallowing despite agreeing to be his guinea pig for this little experiment. It wasn't the first time he'd asked her to, but something about this one made her hesitate. The sound of being in someone else's body didn't sound too appealing, but Law had been pretty confident in his ability, so she played along.

"Relax. I've tried on a few animals before, and it seems to work. Now, hold still." He reassured, walking closer to her with a hole in his chest, before muttering 'Mes' a second time. His outstretched arm passed clean through her own chest, and he retracted it to show her own heart in his other hand.

"Hold these." He instructed, and she gently took hold of both of the organs, rolling her eyes as he stepped a few paces away.

"You know, at one point in my life I would've freaked out if someone told me to hold two still-beating hearts in my hands. Now look at me. I do it just for shits and giggles." She gestured upwards with both of the cubes, and Law smiled thinly.

"Yes, you've adjusted quite well, haven't you?"

"I guess that's one way to put it." She shook her head, watching as Law brought his fingers upwards, face set in determined lines. Her nervousness returned, and she swallowed again. This was something new, and she wasn't sure what came next at this point.

"Shambles." Came his familiar technique, but instead of anything switching places, Lexi watched in fascination as two heart-shaped outlines appeared from out of the hearts in her hands. The brunette couldn't speak as they detached themselves and floated in a circle in the air for a moment, before stopping in place and disappearing back into the cubes.

"Nngh…" Lexi suppressed and groan of pain. Well, not pain exactly, but a deep throb in her chest once they disappeared. She closed her eyes to ward it off. Distantly, she felt the field of Law's Room shrink away into nothingness, it's purpose having finished. The moment passed, the momentary discomforting gone, and she opened her eyes again…

…to see her own body standing a few feet away, still holding the organs.

"What the hell…?" She slowly asked of no one, frowning in confusion. Her body opened it's eyes, blinked a few times, and looked down at the hearts, holding them up a few inches higher to inspect them closer.

"It seems to have worked. How are you feeling?" Law's voice spoke from Lexi's lips, eyes much too serious and confident to be her own.

Lexi moved her—Law's—hands up against the chest she was occupying. Seeing the digits she controlled covered in tattoos was a strange sensation. A glance down confirmed that indeed, she was inside Law's body right now. It was unusual not to see her own breasts right under her chin, but there was only the flat surface of Law's hoodie. Also, she noted with interest, her field of vision was much higher than she was used to.

"This is trippy…" She finally explained, unsure of how to describe the experience. This body felt different, but as if she'd been using it her entire life. Perhaps the transition of bodies was smoother than one would think. "Nothing's in pain, though. And I'm a lot taller than I was a minute ago."

"Hmm…" Law hummed, eyes now skirting around him and inspecting the world through her viewpoint. "You're certainly shorter from this perspective. More so than I thought."

Growling, Lexi pointed down at him accusingly. "Just because that's my body doesn't mean I won't punch you in it."

Ignoring her outburst, he flexed his fingers to get used to the feeling. "Interesting. This could certainly help with infiltration situations. Or even interrogation…" He thought quietly to himself.

"Alright, alright. You've tried your experiment. It worked. Now put me back in my body before you look down my shirt or something." Lexi grumped, crossing her arms with a pout. The expression probably looked comical on Law's face, but she couldn't be bothered to care at that moment.

"It's not like I haven't seen all of you already." Law chuckled, handing her the hearts once again.

"It's the morals behind it!" She snarled, watching as he raised his hand again.

"Room." He muttered, and Lexi waited for the usual blue film to envelope the both of them.

Nothing happened.

Lexi watched a frown come over her body's face, and the fingers twitched. "Room!" Law tried again, but still to no end.

An empty stillness came over the room as the both of them remained silent, the realization hitting the captain and the medic at the same time. Their eyes met and they shared a concerned look.

"You're powers…they must be linked to your body…" Lexi muttered, staring down at the hearts in her hands. "Which means-"

"I can't change us back." Law agreed, turning his face downwards and hiding it behind her hair. "You have to."

Law watched with a mixture of fascination and irk as Lexi, who was stuck in his body, repeatedly gestured with her hand for his usual technique. "Room!" She said again, for perhaps the thirtieth time. Nothing happened, yet again.

"I'm telling you! Concentrate on bringing the energy to a focused point in your hand. You can't just say the command and expect anything to happen!" He chastised, arms crossed. The sensation of breasts above his forearms was new, and slightly heavy. It was strange to think of how much strain they could put on one's spine.

Lexi contorted his own face into something close to panic, clenching his tattooed fingers with worry. The expression was something very unlike him. "I'm trying. Your stupid powers are difficult to understand and control, ok?"

"Well, unless you figure it out, we're stuck like this." He snapped back, more angry at himself than at her. It was his own idea to use himself as one of the participants, wanting to experience his technique first hand so he could better understand it's limitations and applications. Of course, this turn of events had been unprecedented.

Lexi closed her eyes again, obviously trying to shut him out and concentrate. Law quieted down, hoping she was getting the concept and that they'd make progress soon. He wanted his body back already.

"Room." She said again, holding her fingers out like he always did. They waited several seconds, but nothing happened. Defeated, Lexi slumped her shoulders—well, more accurately his shoulders—and let out a pent up breath. "I don't know, I've tried it so many times but I don't feel anything."

Law reached up and rubbed at his forehead. In doing so, he brushed a bunch of stray hair out of his face. How did Lexi manage to do anything with all this hair getting in the way? Trying to keep his frustration in check, he stood and tapped his foot in thought.

"We just have to keep at it." He thought back to years previously, when he was still getting used to having his devil fruit to begin with. "It took me a few weeks to figure out how to really start using my devil fruit-"

"Weeks? Am I gonna be stuck in this body for that long?" She cried, gesturing down at the body she now occupied. Law frowned, bothered by her tone.

"What's wrong with my body?" He asked in irritation.

"Nothing, but think about it! If we get attacked anywhere, I'm going to be expected to fight. With powers I don't know how to use. Plus, you're the Captain. Everyone's gonna think I'm you!"

"We'll come to that when we get there. The crew will have to know immediately, in the event that such things occur." Gesturing for her to stand, Law took their hearts from her and placed them on his desk.

"Shouldn't we put them back in our bodies?" Lexi asked, twisting Law's face into an expression of uncertainty. The captain sighed, resigning himself to seeing his own reflection making faces he would normally never make. It was going to be a long few weeks if that's how long it took.

"I'd rather you have one less ability to learn before we can get ourselves back to normal. The one I used to switch us was difficult to begin with, but Mes is even more so. Not to mention, it requires a great deal of precision."

"Right…" She muttered, wrapping her arms around herself. Law lead them outside the room, towards the mess hall where the crew would be gathering soon for dinner.

Naturally, most of the crew found it rather hilarious that their captain and his lady were stuck in opposite bodies, but most had the tact not to openly laugh about it or otherwise make any comments. Lexi was thankful of that, and dinner proceeded much like normal. Except she noticed the silent glances her way now. It made her a bit uncomfortable, but she tried not to let it show.

"Just ignore it." Law instructed, looking entirely too serious in her body. She couldn't ever recall a time when her own face had looked so stoic and stern before. Jeez, frowning like he was doing now almost looked painful.

They ate their meals in silence, both too preoccupied with their own thoughts to speak. Lexi kept staring at the inked fingers and hands she possessed, running her fingers over the letting unconsciously. A part of her knew they had to have hurt getting them in the first place, but there was no phantom pain.

Law must have noticed her fascination, because he snapped his fingers a few times. "Oi, quit rubbing at my hands like that. It's weird."

Lexi felt a blush creep up her face, which no doubt looked foreign on Law's body. Trying to hold it back, she stuttered and pointed at him accusingly. "Well…well, then stop sitting like a man in my body!"

Law normally sat with his longer legs spread slightly, to make it easier on his knees under the tables. But now, in Lexi's own shorter body, there was no need for it. However he found himself doing it out of habit, making Lexi look much more impolite than she actually was.

"Tch." He scoffed, but did lessen the gap between his knees nonetheless. And Lexi placed her hands in her lap, hiding them from view. They looked away from each other, hoping beyond hope that Lexi learned how to control these powers soon so they wouldn't have to put up with the wrong bodies anymore.

Lexi excused herself from dinner first, wanting to try to use his powers again. When he rose to join her, she stopped him with a hand. "I want to do it alone. You staring at me the whole time doesn't help." Reluctantly, he agreed, then watched her leave the mess deck.

With nothing else to do, Law wandered the halls to see the world from Lexi's perspective. Everything that should have been eye level for him was at least half a foot above his head. No wonder Lexi always got mad at him for calling her short. She certainly was, and he could imagine situations where being reminded of that fact wouldn't be helpful. However, it wouldn't deter him from continuing to do so.

He found himself having to take shorter, faster steps in order to keep pace with what his body's legs could accomplish in half the stride. Another drawback of being short.

Footsteps behind him made him stop, and Law looked back to see Shachi and Penguin approaching. They looked unusually excited about something, and he frowned.

"Lexi-ch- ah, I mean, Captain!" Penguin greeted. "How did you and Lexi-chan get mixed up in each other's bodies exactly?"

Law sighed and shook his head. "It was my own fault. I wanted to experiment with a new ability. When I switch bodies with someone, my powers stay with my body. Now Lexi-ya has to figure out how to use them to return us to normal."

"Ah jeez, that blows." Shachi agreed, unable to prevent the grin from his face however. "But hey, being in Lexi-chan's body has it's perks, yeah?"

Law raised a brow in confusion for a moment, unable to see what they were talking about, before he noticed their gazes were set a little further south than his face. Looking down, he remembered that he was now in the possession of breasts, which were the focus of both of his mechanics' attentions.

"Oi-" He started, about to berate them for acting inappropriately, but Penguin beat him to it.

"Captain, do you think we could just touch them? And…you won't tell Lexi-chan anything right?"

"As a favor to us, man to man. Just once?" Shachi begged, clasping his hands together. "We've dreamed of it ever since she joined the crew-"

Law let out a sigh. "Take your perverted minds somewhere else, bakas." He chastised, pointing back down the hall where they'd come. "Go, before I tell Lexi-ya what you just said."

Their faces were struck with horror, imagining what the brunette would do to them once she found out, and took off with terrified shouts down the hallway towards the mess deck. Satisfied they wouldn't ask that again, Law turned around and continued down the way he'd been going, feeling slightly dirtier than he had been a moment ago.

Lexi's eyes widened, seeing the beginnings of a spinning disc beneath her hands. It was small, almost unnoticeable unless you were looking for it, but it was there. She could feel a tiny rush of energy forming it beneath her palm, swirling in a circular pattern. The fascination with it is what caused her to break concentration, and it broke apart before her eyes.

"Dammit…" She bit, flenching her fists as the moment was gone. It was the first time she'd successfully felt something other than frustration this whole evening. After dozens of attempts at trying, she finally began to show progress.

Not having Law around to push her further was a little helpful too, but she knew he'd be returning from dinner soon. To which he'd probably end up sitting beside her trying to help. She knew he was doing it with good intentions, having insight into how the powers worked, but his constant frowning was making her a bit nervous. Plus, seeing her own body staring at her was…sort of creepy.

She took a deep breath and calmed herself, bringing her hands up like usual. Trying to emulate Law, and repeat what she just accomplished, she imagined some sort of energy pooling in her hand. "Room." She said hopefully.

The swirling sensation returned, and she saw the blue disc a bit clearer this time. However, she also remembered that Law said it sucked his stamina away if he used the ability too much. She found herself panting within a minute or two of trying to strengthen the disc to something closer to what Law could form.

Her hand began shaking with the strain, and she finally dropped it out of exhaustion. Her chest heaved and she leaned back against the bed. Lexi couldn't imagine the strain Law normally put himself through just to maintain one of his giant rooms, let alone actually form one. Of course, perhaps most of it was a mental strain rather than physical, to which Lexi was nowhere near as enduring as her Captain. He'd been practicing these things for years.

The bedroom door opened to reveal said Captain, quirking a brow when he noticed she were sitting on the ground in exhaustion.

"I was able to form that blue disc thing, but only for a second." She admitted, waving her hand excitedly. "I get why you try to use your ability only minimally though. I feel drained."

"Yes, it's a great strain after too many uses. Looks like you'll have to slowly build up an endurance for it as well. That'll take time and practice." He admitted, sighing and rubbing the back of his neck. It seemed her hair was irritating him, because he moved it away from his neck in frustration.

"Still getting used to my body's quirks?" Lexi inquired, watching from the floor with amusement. Law scowled and shook his head.

"How do you get anything done with all this hair? It's constantly getting in my face."

Lexi shrugged with a chuckle. "It's an art." Her joke fell a little flat, seeing as Law didn't laugh at it, but she didn't care. "You'll just have to get used to it, as you so kindly put it earlier. I have to deal with having a dick, and you've gotta deal with breasts. Simple as that."

Lexi heard him grumble a few incomprehensible curses under his breath, before disappearing into the bathroom nearby. She stood then, having regained some of her strength from before. "Where are you going?"

"Taking a shower."

Lexi was about to yell at him not to, but then realized that if they were going to be stuck in each other's bodies for a long period of time, they'd also have to wash them appropriately too. Which meant Lexi would also have to bathe Law's body too. The thought both unnerved her and excited her. With such short hair, she could be in and out in a matter of minutes.

Maybe being a guy had some perks.

Lexi was shaken from her thoughts as the shower turned on. Deciding that she was too drained to keep practicing for the night, Lexi stood and wandered over to the bed, flopping down onto it unceremoniously. Stretching out liberally, she closed her eyes and relaxed, keeping an ear out for if Law had any issues.

Law stood under the spray of the shower, suddenly all the more aware of how many shower products Lexi possessed. He'd always known she had quite a few products, but never really paid them any mind until now. The two bottles of shampoo and conditioner were self explanatory, but the other five tubes and bottles left him a little confused. Face cleanser. Facial scrub. Body lotion. Scented body soap. The list went on, and Law realized why it took her forever to take showers.

"Do you really use every single one of these products?" He called, inspecting a few of them incredulously. He wasn't even sure if he knew how to use some of these properly.

"You bet, though some I do every other time to give my skin a break." She responded casually.

"I've never seen you use them when I join you." He hinted, almost wanting to call a bluff so he wouldn't have to figure all of this out. He could hear Lexi laugh from the bedroom.

"You think I'd really want to go through that whole routine when there's a hot pirate in the shower with me? I don't think so."

Law smirked proudly but sighed nonetheless, opening the bottle of shampoo that smelled like strawberries and resigning himself to the fact that he'd be smelling like a female for the next little while. He squirted out about as much as he normally did for his shampoo and began to lather it in his—Lexi's—hair.

It took only a moment to realize that was nowhere near enough, and he opened the bottle for more. Curse Lexi's long hair. This was going to take a bit longer than he thought.

Almost 45 minutes later, Lexi watched as Law came out from the bathroom wrapped in a towel. She was at least thankful he wasn't taking every opportunity to simply be in her body naked. Nice to know he respected her at least that much. His wet hair lay in strands across his shoulders, and he held her comb in his hands.

"I'm half tempted to cut your hair while I''m stuck in your body." He mused, and she glared at him.

"Don't even joke about that."

Shrugging, Law went looking for some clothes to wear, all the while trying to detangle the mess that was Lexi's head of hair. She winced when he dragged the comb roughly through the tangles, no doubt causing more damage than good.

"Hey, be gentle! You're gonna rip all my hair out at that rate!" She chastised from the bed, and Law scoffed. Still, he at least tried combing through it a bit gentler, but it still made her anxious.

"Ok, please put down the comb. It's painful just watching you try." She stood and wandered over to him, stealing the comb from his hand. "Just put some clothes on and I'll untangle it myself."

Once Law had found a t-shirt and shorts to sleep in, he found himself sitting cross-legged in front of his own body, scowling as Lexi combed through her own hair in a much gentler fashion than Law had tried earlier. Occasionally, he could feel the comb tugging on his head but it was bearable. Barely even painful. Lexi apparently was very fond of her long hair, and treated it as well as she could.

Law had never had that problem, barely needing a comb to bring his all into order.

So he relented and let her take care of this little problem for herself. It was almost sort of…relaxing, the sensation of a comb gently passing across his scalp. He wondered if she thought it was too.

"You're doing well." He blurted out unexpectedly, realizing he'd been pretty bitter towards her all day. The comb paused a moment before starting up again. He elaborated. "It's not you I'm angry at, but I've been taking it out on you. It wasn't my intention."

"It's alright. I'm used to your moods by now." She replied lightheartedly, appearing to ignore his growl of warning. "I'm sure I'll figure out how to use your powers right eventually. It's just a matter of when. I mean, if you could figure them out when you were a kid, I'm sure I could do it too as an adult."

Law nodded silently, thinking she couldn't have phrased it better.

"Did you have someone to help you figure everything at the beginning too?" She inquired, wondering if there were people who could teach those things, but Law shook his head.

"No, everything I know about my devil fruit is self-taught. It took years for me to get to this point, and I'm still learning new things about it."

"That's pretty impressive, you know. Learning something like that by yourself without any help…not something I'd be happy to do." She said quietly, finishing up combing through her body's hair. "Thanks for helping me figure it out."

Law hummed, pushing himself up so Lexi could stand. She put the comb back on the bathroom counter. Law glanced at the clock and noticed it was getting pretty late.

"We may as well get some sleep. It'll make sure you're refreshed in the morning to keep trying."

"Sure thing." She said, yawning openly. She clambered over to her side of the bed, getting herself comfortable underneath the covers. Law did the same over on the other side, and the only sound in the room was the shuffling of sheets and linens. Lexi turned off the lamp on her side of the bed, plunging the room in darkness.

Law went to lay on his side like he was accustomed to do, shirting his body to become more comfortable. What he hadn't anticipated, or thought of, was the addition of breasts into the equation. They were pressed painfully into the mattress, half trapped underneath his own body. Scowling to himself, he tried shifting onto his chest, another of his usual sleeping positions, but this only made things worse by resting his entire weight onto the fleshy mounds.

Finally, he was forced to sleep on his back. It wasn't one of his normal sleeping positions, as Law had always found it difficult to sleep this way, but it was the most convenient for the body he was stuck in now. Law tried not to let the sigh come out too loud, but it still did anyway.

"Breasts are very inconvenient." He muttered, causing Lexi to chuckle under her breath beside him.

Lexi stood frozen at the two bathroom doors, unsure of which one to go into. A few crew members passed her by, smirking when they noticed her internal dilemma. However, none of them offered up any sort of solution to her problem and kept walking. Feeling a blush creep up her cheeks, she turned and walked away towards the Captain quarters. She was not about to go into the wrong one and cause a scene. Looks like she was going to have to use their own until they got things back to normal.

It was a few days later that Law asked her to train a bit with his body to get more familiar with it combat-wise. She'd blanched, stuttering a quick disagreement, but Law was adamant. "Should we run into trouble, I don't want you completely helpless." Was all he'd said, before ushering her into the training room.

Thankfully, only Shachi and Penguin were in the room with them, making Lexi a bit more comfortable. It was weird to be walking around in Law's body, knowing full well her mannerisms weren't anything like his. Come to think of it, it must have been strange on the crew's part to be seeing their Captain acting so unlike himself.

"Shachi-ya, Penguin-ya, I'd like you two to help train her while she's in my body." He gestured to Lexi, who stood there uneasily.

The engineers nodded, and wandered over to join them. "Don't worry, Lexi-chan. We're not going to seriously hurt you or anything."

"We'll start off with basic techniques, but slowly get into more serious fighting as you become used to using my body for combat." Law explained, hanging back and watching from the sidelines.

Law quickly realized that although Lexi had never participated in straight hand-to-hand combat before, his body's muscle memory must have been retained when she took it over, because despite her inexperience she was doing rather well. Most of Penguin's and Shachi's punches were deflected or blocked, and the speed at which she retaliated was more than what he would have expected for her. They still landed quite a few hits, but less than he would have expected.

It seemed Lexi had come to the same conclusion, because after some time of practicing, she shook out her hands and stared at them. "It's weird, but I feel like I know what to do even when I've never done anything like this before."

"Perhaps the natural instinct for self preservation and some muscle memory stick with the body as well…" Law finally mused his hypothesis aloud, rubbing at his chin in thought. "Let's keep going, however. I want you to be exposed to all types of situations, in case you find yourself having to be in a fight in my body."

So they continued. Shachi and Penguin both took turns attacking from different angles and using different styles. Lexi was able to keep up with most, but there was a distinct lack of finesse or confidence to her movements. She was still panicking.

Law finally asked both of his mechanics to attack her at once, knowing that against an enemy pirate crew, or even the Navy for that matter, it was impossible to believe they'd stay true to one-on-one fights. Ganging up was a favorite tactic.

Shachi stood behind her, Penguin in front, and she glanced back and forth to watch the both of them. Penguin made the first move, and Lexi was barely able to catch his first punch before rounding to block the kick Shachi sent towards her knee.

They sparred like this for several seconds, with Lexi holding her own reasonably well, but it was apparent that two enemies was more than she could take. Her movements began to slow, her responding attacks easier to dodge or deflect. Law watched proudly as she kept going anyways.

Finally, it all came to a head when she turned to avoid Shachi's punch, only to walk straight into the kick that Penguin threw…

Straight into her crotch.

Law winced at the phantom sensation of just how much that hurt, and watched in shared agony as Lexi cried out in pain and collapsed to the floor. He thought, not for the first time, that women had no idea just how much that particular wound could hurt, but figured Lexi probably knew well enough now.

"Fucking hell…" She gasped out, tucking her legs up a bit protectively.

"Lexi-chan! Are you ok?" Penguin asked, dropping his attack stance and moving to help her up along with Shachi, but she waved the both of them away.

"Fine." She bit out, curled up on the floor. "Fuck, I…ugh…just need a sec."

Law took pity on her and approached the fighters. "I'd say that's enough for the time being. We'll start back up later and practice some more."

Lexi groaned from the floor, and Shachi and Penguin reluctantly let the both of them be, feeling bad for causing the brunette so much pain. They both winced too, imagining if it had been one of them to get kicked in the balls. They shuddered and moved quickly down the hallway.

"Captain! Navy ship inbound!" Bepo's cried, eyes still staring at the radar screen intently, and Law scowled in the brunette's body.

"Damn…" He muttered, gripping the back on Bepo's chair tighter. He was afraid this would happen eventually. "What's the ETA?"

"About 3 minutes, from the east."

Jean Bart, who was at the periscope, interrupted them. "They've already started prepping cannons for attack."

Law bit back the curse, wondering how on earth they'd surprised them like this out of nowhere. "Have the crew prepare for a fight."

"Aye, Captain!" The first mate called, pressing a few buttons and finally reaching for the speaker that projected to the entire sub for announcements such as this. Law left his navigators be and went to find Lexi. His shorter legs ran through the hallways as he passed some of his crew. They gave him only a glance but continued on towards the armory for their weapons, even as Bepo continued informing them of the threat approaching. Law kept running, navigating the sub easily.

He rounded a corner and saw her looking around uneasily. "Lexi-ya!" He called, garnering her attention. She met him halfway.

"What's going on?"

"A Navy ship is approaching." He explained, feeling a rumble and hearing a great splash of water outside the sub as what he presumed to be a cannonball landed in the water not far from them. The sub rocked a bit more violently from the force, but was otherwise undamaged. "Where is my sword?"

Lexi's eyes flitted about nervously, trying to remember. "Umm…uh…you…you left it in the training room I think!" She finally recalled, snapping her fingers. Nodding, he lead her through the halls.

The room was empty, most of the crew having gathered in the armory on the opposite side of the sub. Another violent rocking made them eerily aware that the threat was still approaching. Law's sword sat in the corner, where Lexi had last put it. He'd insisted she at least get herself familiar with it in case something happened.

Law went to grab the weapon but struggled to keep it hefted. He frowned, then turned towards Lexi. It was what he'd feared. Lexi had nowhere near enough strength in her body to properly use his sword, even if he had the instinct and mindset to actually wield it.

"I'm gonna have to go out there, aren't I?" She asked, eyes widening in a panic. He nodded silently, handing her the sword. She lifted it easily, possessing Law's muscles that had been honed to do exactly that. She unsheathed it and stared at the blade.

"Keep in mind what we learned in practice." He reminded, pushing her out towards the door. Then, he paused, whirling her to face him again. "And please, don't go swinging your sword in the direction of the crew."

She nodded several times, swallowing nervously, before following after him. Law grabbed a few pistols from the armory, knowing Lexi was rather proficient in using them, and joined the rest of his crew out on the outside deck of the sub.

In the back of his mind, he registered the thick fog that hung over the ocean here, figuring that was how they'd been surprised in the first place. The second was the immense navy ship about to come alongside them.

The Heart Pirates gave a battle cry, waving their weapons in the air, and the Navy responded in a similar fashion. Once they'd drifted close enough, men from the Navy began to jump over the side onto the yellow deck below, clashing with the pirates waiting.

Law remained by Lexi's side just in case, guns at the ready. The brunt of the battle between the crew began, and the sound of clashing swords and gunshots rang around them. More Marines spilled onto their deck.

"Hyaa!" Lexi heard, watching the polar bear fly across the deck in a spinning fashion. Left and right, soldiers went flying into the water. She grinned, finding it a little funny.

"Trafalgar Law!" A cry came from behind her. Startled, she spun just in time to see a Marine had somehow snuck their way behind them, and was sprinting towards her full pelt with his sword raised threateningly.

Law's blessed muscle memory kicked in at that moment, and she unsheathed the sword with a flourish, bringing it up just in time to block it. She expected the strength of the man before her to push her back, but Law's body stuck in place, meeting the angry soldier with just as much strength.

A gunshot rang out right beside her, and the Marine slowly dropped to his knees, a red stain growing across his chest. He collapsed to the deck, and Lexi looked over to see Law lower the gun he'd shot to his side again.

"Well done." He complimented, meeting her eye. "But we've only just started." He gestured with his head back towards the deck, where most of the space was occupied with individual fights. Law's crew were slowly but surely pushing back, if he could see correctly.

Lexi glanced over at the ship, noticing a man standing out at the edge. He wore one of the white-colored, grandiose coats that the higher ranked officers had. Their eyes met, and he chose that moment to jump down from the ship, slicing men left and right as he made his way closer to them.

"Shit…" She muttered, watching as he jumped several feet in the air and landed on the edge of the railing closest to her.

Beside her, Law was focused on several men that hoped to come up from behind her, and so did not see the much bigger threat approaching them.

Something caused her to look back up, and she brought the sword up as well, blocking the sword stroke that would have decapitated her had she not been paying attention. Standing her ground, the force behind the attack caused her to slide back several inches. Gritting her teeth, Lexi pushed back with all she could.

"I'll take pleasure in finally killing you, pirate." The officer spat venomously between them. Lexi shoved him back, disgusted by his threat. He immediately went back in on the offensive, forcing Lexi to black and deflect the sword strokes as she could.

At this rate, she'd only be pushed back and at risk of getting hurt, so Lexi turned the sword and tried a swing of her own, watching with disappointment as the man easily blocked it.

"What's this? I expected you to be a bit more dangerous than that. You'd best not be holding back on me, now. I'm insulted." He said again, pushing back and almost causing her to stumble. She recovered her balance and was just in time to block another attack aimed at her neck. The blades clashed, shaking against each other with the strength of both opponents.

"Hmm, and no smart mouth either? Today's just not your day is it?"

Lexi was getting fed up with the man's words, and she used her anger to fuel her next few attacks. Swinging and hacking away at him. She was pleased to see he gave a few feet in ground. It wouldn't last long, she knew, but it was better than nothing.

The Navy officer flicked his blade to the side, deflecting the bullets that Law shot at him, trying to help Lexi in some way. It seemed he'd taken care of the others that had been trying to attack her from behind, but the firepower hadn't done much in way of help. However, it had drawn his attention away for just a moment, giving Lexi the opportunity to take advantage of the idea that had been forming in her mind since the start of the fight.

She hadn't imagined actually using Law's abilities in combat. The concentration it required was high, but all the anger she had facing him, an unprecedented amount, seemed to help. Growling, she brought her hand up behind her back, feeling that swirling energy come to the forefront.

"Room." She muttered, too low for the Marine to hear. His attention now back on her, he aimed an overhead stroke down towards her, but she jumped back to avoid it, giving some space between the both of them.

Thanking the hours and hours of practice Law had her do over the past several days, she was pleased to see the blue film expand around them over the battlefield. It reached past the ship, surprising even her. But she was too angry to think much more on it, before she gripped her sword and swung violently towards the man with a grunt of exertion.

It appeared he hadn't yet recovered from his overhead attack, as he staggered back a few paces but otherwise was unable to escape the radius of Lexi's attack. Her cut carried much farther than the reach of the sword, slicing the man in half at the waist. He cried out, but it was deafened by the rumbling of the ship behind him.

Combatants turned and saw the top half of the ship floating upwards from where she'd cleaved through it. The Marines fighting cried out in panic, giving the pirates the edge they needed to turn the tide of victory.

Another gunshot rang, and the man's upper half was sent spinning through the air of Lexi's room. The sword he'd carried was released, and it spun away in a different direction from his torso. Flecks of blood were stuck in stasis around him. Lexi looked over and saw Law staring up at the man with a pleased smirk.

Feeling the adrenaline beginning to wear off as the battle slowly died down, she lowered the tip of the sword and the room disappeared again. The surviving Marines, seeing their leader defeated, had turned tail and jumped into the ocean below in an attempt to return to their ship. However, as soon as the blue film was released, the top half of the ship came crashing down on top of the lower portion, causing the whole structure to snap and creak with the unexpected weight. Wood beams splintered, metal railings were flung this way and that, and the men cried out in fear again, this time dodging wreckage and ruin from their own ship.

"Bepo! Set as course away from here!" Law took charge again, pointing towards the entrance of the sub again. "Everyone inside! Help any wounded to the med bay!"

Law's orders carried over the fading sounds of victory from his men, and everyone rushed to do as he'd instructed. Lexi stood there swaying a moment, but eventually found the sheath for Law's sword and joined the rest of the crew.

Lexi returned to their room and sighed, running a hand through her short hair. She was still getting used to the sensation of not having her longer locks, but as long as Law didn't make good on his threat to actually go cutting it, she'd patiently wait to have it back. It was just after dinner, and she'd been practicing Law's abilities all day. It was exhausting work, but her skills were slowly getting better. As she'd shown in the battle against the Navy, she could successfully form a Room. All that was left to learn was the personality transplant surgery which, according to Law, was one of the more difficult ones to perform. Just great.

She rubbed at her head, thinking about taking a shower to rid herself of the sweat that had formed from all of her practice. She walked to the closet attached to the bathroom, searching for a clean towel. Her eyes travelled the wardrobe and dresser, narrowing when she saw several pieces of paper stuffed away at the very top. Her usual height prevented her from seeing that high up, but Law's extra height made it possible.

Reaching for them, she was mortified to find they were porn magazines. Feeling her cheeks heat up, she went to put them back. Then, a little miffed, she wondered why on earth Law had these. Wasn't she enough? Pouting through her slight anger, she flipped through some of them just to see what all the fuss was about. And to gauge if any of the women were more attractive than her.

Even after the first couple pages, with scantily-dressed or completely nude women adorning them, Lexi's pride took a hit as she came to the conclusion that yes, they were all leagues more attractive than her. And what was worse, only a couple out of the girls shown were brunette. Was brown hair not his type? Damn, she never should have picked this up to begin with.

Tensing, Lexi felt a tight sensation in the crotch of the jeans she was wearing, and looked down to see an obvious bulge. Horrified, she quickly tossed the magazine back where it belonged and began to undress. It was a good thing she had intended to take a shower to begin with, because a cold one was now very much in order.

She'd pretend that she never saw those magazines to begin with.

Rubbing at the headache that was beginning to form, Lexi brought up her hand and muttered 'Room' with little enthusiasm. The blue film expanded around the both of them as they sat on the floor. Law looked to be just as tired, but they were eager to get back to normal, so they kept at it anyway.

"Now, don't concentrate on the physical cubes, but both of our minds. It's not the hearts you're switching, it's the personalities." He reminded, holding both of the beating organs in his hands.

Nodding mutely, and holding back the expletive words she really wanted to say, she held up her hand and stared intensely at the cubes.

"Shambles." She said, twisting her hand as he instructed to do. Just like the last time, the hearts switched places, coming to rest again on opposite hands. Law sighed quietly but said nothing. Frustrated with herself, she shook her head and tried again. "Shambles."

The same result.

"Dammit…" She muttered, shifting her position on the floor to something more comfortable. Maybe that would help.

"Try to focus." He reminded, and she glared at him angrily.

"You telling me to focus does not make me more inclined to focus, funnily enough."

He frowned in return. "I'm only trying to help."

"Well, being quiet would be much more helpful, thanks." She bit, holding up her hand again. "Shambles!"

Still, the hearts switched places but she was still stuck in his body. It appeared Law couldn't help but point out her mistakes, because he shook his head again. "You're focused too much on the hearts."

"What do you want from me?" She cried, throwing her hands up in frustration. The room released around them as she lost concentration on keeping it active. Snarling, Law set the hearts down on the ground and stood.

"I want you to do as I instruct. If you did, we would be back to normal by now."

Lexi stood as well, stepping past him and pacing in a few directions. "It's not that simple."

"I know exactly how simple it is. I'm the one who created the technique!" He said angrily, meeting her face to face again. She whirled to face him again.

"Look, I'm sorry I'm not some goddamn genius, ok? Sorry I can't figure out something in a week what it took you years to do! Lay off me, I'm trying my best!"

Lexi watched as Law smirked, then went to retrieve the two hearts from the floor. "Well, obviously your best isn't good enough."

"Tch." She scoffed, gritting her teeth and clenching her fists. Where in the hell was this coming from? Law had been patient thus far in her attempts to learn his abilities. Why was he being an asshole about it now? Her anger bubbled over, and she dismissively waved him off. "Fuck you, Law."

"If you have time to curse at me, then you have time to try again." He stated bluntly, holding up the hearts again. "Create a Room."

"…" She bit her lip but did as instructed, her hands shaking with fury. The blue film expanded, much quicker than her previous ones had. She brought her fingers up and twisted. "Shambles."

Once again, the hearts simply switched places, and Law narrowed his eyes at her. "Again."

"Shambles!" She tried again, pissed at the same result. This was getting to be ridiculous. All this practice was tiring her out and she was hungry. Lexi was almost tempted to give it up, but Law was having none of it.

"Again."

"Shambles."

"Again!"

"Shambles!"

"Again!" He barked, the command cutting at her like a whip.

Him yelling at her was the last straw. Closing her eyes to shut him out, she jerkily twisted her wrist. The fury she held towards him came out clearly in the single word she shouted. "Shambles!"

Startled, Lexi felt that deep throb in the center of her chest again, followed by a mild wave of discomfort, before she blinked and saw Law standing in front of her. She looked down and saw the hearts still beating in her hands, and she let out a pent up breath.

"…it worked." She said quietly, feeling some of her anger start to fade. Law dropped the room around them and grabbed one of the hearts, squeezing minutely. He winced, satisfied it was indeed his, before returning it to his chest. A sigh of relief left his lips and he stretched his arms above him.

"Finally." He stated, smiling with contentment.

Lexi set her own heart back in her chest, then frowned, thinking back to the past several minutes. "You know, you didn't have to be an ass about all of that." Crossing her arms, she turned and walked towards the bathroom, intent on brushing her tangles hair since it was clear Law hadn't taken the time to take care of it like she did.

A hand on her shoulder made her stop, and Law faced her. "When emotions are high like that, I find it easier to use some of my abilities. So, I thought it may be the same case for you."

"You could have told me you know!" She griped, trying to leave again but he stopped her.

"Had I told you straight off the bat, they would have been forced, and it may not have worked as well." Law reasoned, finally releasing her from his grip. She glared at him a few seconds, before giving a soft 'hmph' and turning towards the bathroom again.

He didn't follow after her, and she set to getting her hair back into place. Despite still carrying some of the traces of anger from before, her smile was wide and genuine. She was finally able to see her own face in the mirror again, and everything felt normal. Even her shortness didn't bother her for once.

Yes, it was good to be Lexi again.

A/N- Well, unfortunate for the both of them, but I'm sure they learned something from this little adventure! Quite fun to write, this chapter was. There's one other prompt that I may do in the immediate future, but I'm not sure yet. We shall see!

Anyways, as always, don't forget to leave a review if you enjoyed! I love reading your comments. :)
