(A/N) Hi all! I know, I know - I said I'd be good just writing original fillers for my other Steve/Kono episode fic... but I couldn't stay away! :) Hehe. Ideas kept bouncing around my head until I got it onto paper. You know how that goes, guys. Haha. Well, anyway, this was one idea that I liked - featuring Mary (a character who has soo much potential, in my opinion). She's going to act as us Kono shippers, pushing Steve and Kono along, hehe. This fic will probably be a 2 or 3 parter. Hope you guys like it. :)

Onwards!


Mary Ann McGarrett sat up for what had to be the millionth time that night and growled in frustration.

She turned to the wall behind her and cupped her mouth to it, yelling, "Hey, can you keep it down in there? Some of us are trying to sleep?"

Then she sat back and paused, listening. The sounds from the other room continued.

Mary plopped back onto her pillow and groaned. It's going to be a long night.


When the morning finally, blissfully, arrived, Mary Ann climbed out of bed, one heavy leg at a time. Ugh.

She wrapped a sweater around her bare shoulders and tank top, then sleepily walked towards her childhood bathroom. She realized that since she felt like shit, she probably looked like it, too.

She swung open her door and stopped short.

"Oh!"

Standing in the doorway was none other than Catherine, her brother's Navy girlfriend and one-half the source of her sleepless night. Needless to say, Mary wasn't exactly thrilled to see her. She glanced down briefly at Catherine's attire – one of Steve's big t-shirts and nothing else – and pursed her lips.

"Hi," Catherine started, smiling hesitantly. "I'm Catherine. You must be Mary? Steve's sister?"

For a second, Mary was tempted to lie and say that no, she was Steve's other girlfriend – but decided that that would be low, even for her standards. Instead, she only raised an eyebrow and drawled, "Good night last night?"

"I'm sorry?"

"Old house. Thin walls."

Catherine immediately flushed in embarrassment. She put her face in her hands. "Oh God."

"Yeah, you were saying that a lot last night."

"Ugh. I'm so sorry," Catherine continued, voice muffled against her palms.

"Yeah." Mary narrowed her eyes and smirked. "That's okay, though. I just broke up with my boyfriend, so I'll be bringing a lot of guys around here soon."

Catherine didn't answer. Mary took the opportunity to shoot her a smirk, slide past her in the doorway into the restroom, and slam the door.


Steve McGarrett was driving to the ME's office when he realized that his phone was ringing. A remnant of a smile still on his face from his good night, he kept his eyes on the road and pressed Talk.

"McGarrett."

"Good morning, Steve." The female voice on the other line was flat, almost accusatory.

Steve exhaled sharply, his eyebrows knitting wearily. Crap. "Mary. Are you okay?"

"Oh, you remembered to ask! Because for a second there, I thought you forgot that your little sister was living in your house."

"What are you talking about?"

"There is no food in this house. And I have no money."

Oh, right.

"Too busy screwing your nasty girlfriend to remember to take care of your guest?"

Steve frowned. "You don't like Catherine?"

"Yeah, I don't even know why. It's not so much that I don't like her… it's more like she annoys the fuck out of me."

"Language."

Mary scoffed. "Thanks, Dad," she snapped sarcastically.

There was a long, awful silence.

"God. Sorry," Mary mumbled, voice softening.

Steve sighed, gripping the steering wheel tighter as he followed through a turn. His voice softened too. "Okay, Mary. The keys to the other car are in the desk in my room. And I'll ask Kono to drop by with some food and money for you, all right?"

"Kono?"

"You remember. My teammate."

"Oh, her!" Mary's voice brightened slightly. "Awesome. She's cool."

"Yeah," Steve smiled. "Yeah, she's pretty cool."

"Now that's the type of girl you should be dating, Steve. Hottie who surfs by day and kicks bad guy ass by night? How are you not trying to bang this chick? It's ridiculous."

Steve laughed. "Do you want me to date her, or do you?"

"Hah, very funny." Mary paused. Steve could practically hear the smirk in her voice as she continued, "Just know that I got this idea in. Now you can never again look at Kono without remembering this conversation. I'm in your head…" she teased in a sing-song voice.

"I'm hanging up now, Mary," Steve called towards his speaker. And he did, smirking.


Steve pressed '2' on his speed dial.

The girl picked up on the last ring before voicemail. "Hello?" Kono muttered groggily, obviously having just woken up.

Steve imagined Kono lying in her bed on this beautiful Hawaiian Saturday morning, in a tank top and rolled up pajama shorts, and he instantly felt guilty for dragging the girl up. He grimaced and said, "Kono, I'm sorry to wake you – but seeing as we'll all need to be at headquarters in a little bit, can I ask you to do something for me before work?"

There was the sound of rustling covers. "McGarrett?" she asked, after a pause. "You do know it's Saturday, right?"

Don't remind me. "Special orders from the Governor. She called Danny and I over to the ME's office. I'm on my way now. You and Chin were supposed to meet us at HQ in an hour."

Another pause. When Kono spoke again, it was with a playful tone. "And you couldn't let me sleep the extra hour?"

"I know. I'm sorry. I wouldn't have asked, but it's Mary."

"What's wrong?"

"Apparently, a matter of life and death – omelets gone missing from the McGarrett home."

Without missing a beat, Kono deadpanned, "Roger that. So would we classify as a MISPER or a MISEGG?"

"She'll make sure I'm the MISPER if I don't get some food over to her by noon."

They laughed.

"Okay," Kono replied, trace of a smile in her sleek voice. "So I'll pick up some groceries and drop it off, then head over to HQ. No problem."

"Thanks, Kono." Steve exhaled and smiled. "Mary really likes you, you know."

"She does?"

"Yeah." He didn't mention the reason why. His mind drifted to Mary's words – I'm in your head, followed by a brief image of Kono's smiling face, her dimples deepening against her tan skin –and he cleared his throat to recompose himself. "I'll text you my address. Thanks again. See you at headquarters."

He hung up before she could answer. Damn it, Mary, he silently cursed, concentrating back on the narrow roads.


"Hello?" Kono called into the McGarrett house, pushing the door ajar. She didn't know why, but she felt a sense of foreboding; perhaps a vestigial instinct from entering unfamiliar houses on missions. After all, this was the first time in a long while that Kono was entering a house without having a loaded gun in her hands.

Suddenly, Mary popped out into the hallway. "Hey," she greeted with a one-sided smile that matched her brother's. "Kono, right?"

"Right." Kono grinned and held out a bag in response. "And I brought sustenance."

"Oh my God, thank you." Mary practically jumped at it, then backtracked. She frowned and sighed. "Also, I'm really sorry I made you come all the way here. I was kind of a jerk to Steve earlier…. but it was only because I was hungry, I promise. Like, I get cranky when I'm hungry or tired. And I was both; seeing as Catherine stayed over last night." Her eyes rolled to the ceiling.

"Who's Catherine?" Kono asked.

"I am."

Kono and Mary turned around at the sound of the voice. The former was taken aback, the latter looked annoyed. Catherine only looked uncomfortable – even though she was fully clothed now.

"Oh. Hi," Kono greeted her with a smile. "It's nice to meet you."

"Likewise," Catherine responded, looking wary. "Who did you say you were?"

Kono chuckled. "I didn't. I'm Kono. I work with Steve. His teammate." Her voice went up at the end as if it was a question.

"Oh, you're Kono." Catherine smiled. "Yeah, he talks about you a lot."

"He does, does he?" Mary cut in, grinning. She was going to have to ask Steve about that later.

"Yeah, but he never mentioned you were a girl. You must be really good at what you do to be able to hang with them."

Kono grinned modestly. "Thanks. I'm okay, I guess. I'm just really thankful to be part of the 5-0 team."

"Of course."

Mary's gaze flitted from Kono to Catherine and back. She smirked mischievously. "Yeah, but all those long hours together with your team? Must get tiring to be around them all the time, doesn't it?" She emphasized the words purposefully.

Kono didn't seem to catch on. "Oh, yeah, no, it's all right. We have a good time."

Mary smirked triumphantly.

"Okay." Judging by the look on Catherine's face, she had realized what Mary Ann was trying to do. "Well, I should really be getting back. It was nice to meet you, though, Kono." She gave Kono a smile and then turned to Mary. "Mary, tell Steve I said thanks for the hospitality and I'll see him tonight?"

"Will do."

With a final smile and tiny wave, Catherine slid past the two other women and out the front door.

"Will not do," Mary muttered, once Catherine was out of earshot.

Kono laughed and leaned against the couch. "I'm guessing you don't like her."

"That obvious?"

"Why not? She seems nice enough."

"I know, right? But I just don't think she's right for Steve."

"Oh, really?" Kono smiled. "That's nice of you, being protective of your older brother."

Mary Ann scoffed. "Yeah, it's funny, isn't it? I don't see the guy for ten years, but I still want him to be happy."

"He's not happy with Catherine?"

"Let's just put it this way." Mary folded her arms and smirked. "I think he'd be much happier with someone a little more on his level. You know. Someone like you."

Instantly, Kono's cheeks flushed. "What?" she laughed and scoffed, taken aback.

Mary shrugged, as if saying It's true.

"Steve's my teammate," Kono demurred appropriately.

"Yeah. Well." Mary smirked mischievously. "Just know that I got this idea in. Now you can never again look at my brother without remembering this conversation. I'm in your head…" she teased, in a sing-song voice.

"Okay, okay, I'm leaving now, Mary," Kono called purposefully and loudly, laughing as she headed out the door and smirked in goodbye.
