This story takes place on an Earth where Supergirl is a part of the rest of the Arrowverse. Major events referred to in the story that have been shown on Supergirl, The Flash, or Arrow are assumed to have happened in some general shape or form on this Earth, but the main players and chronological order won't necessarily be the same, and some interpersonal relationships are also different. Legends of Tomorrow's canon won't be too relevant, but it's assumed the crew is on present-day Earth for the duration of the story. The rating for this is K+ for occasional mild language and suggestive scenes.

As always, all characters belong to DC Comics and the CW. This is written purely for fun. Thanks so much for reading. I appreciate it.

…

"Nope," Alex laughed, as Kara groaned again. She let go of her sister's arm and put her hands on her hips in frustration.

Despite revealing herself as Supergirl years ago and getting pushed to her limits in training by the DEO, and later the Justice League, Kara still came out on the losing end in the Kryptonite training room against Alex. Admittedly, Kara was a fast learner, and in the early days of her training, particularly on days when Kara's focus was razor-sharp, she seemed to hold her own or even beat Alex one-on-one. However, she eventually caught on that it was Alex who typically held back, despite her constant lectures to Kara about forgetting the fact they were family.

"You have to really jut your hips back, or you won't get the right leverage," Alex explained, the sisters lining up to try again. Kara was trying to counter Alex's punch with a throw, but she couldn't arrange her body the right way to execute it correctly. Squaring off, the sisters closed the distance between them again and resumed trading blows, their sequence of punches and counters flowing from one motion to the next.

It'd taken Kara learning enough to actually become a decent fighter to realize that, when Alex brought her A-game, when she viewed Kara as an adversary and not her little sister, Alex was in fact way, way above her level. She'd become sick of how wide the gap still was between them, so she'd recently bugged Alex to step up their sessions and help her learn all the tricks and techniques that Alex used effortlessly.

Finally, within the flow of their sparring session, Alex threw a long, telegraphed punch at Kara's face, and Kara spun around, blocking the punch first before grabbing her sister's arm and twisting her body so that her back was to Alex. She tried to use that grip to flip Alex over her shoulder, but she couldn't get her sister all the way over, leaving Alex draped over her back like a sack of potatoes.

"Nope," Alex laughed again. "You need to flip me, not give me a piggy-back ride."

"I'm trying!" Kara said, letting go of Alex so she could get back on her feet. "You make it look so easy."

"Hey, we've only just started practicing this throw," Alex soothed. "You'll get it eventually."

"I know," Kara sighed. "I just get embarrassed watching Oliver, Roy, and Thea training together, with all the crazy martial arts stuff that they do. All the sticks, and the flying kicks, and the counter moves. I'm standing to the side, like, 'Um, I can punch really hard…'"

"Hey, that's not fair. You can hold your own in a fight. The DEO wouldn't have let you out of our sights if you couldn't," Alex reasoned.

"Yeah, I know," Kara agreed again. "I guess I'd just like it known by any bad guys out there that my skills go beyond flying and zapping things with my eyes."

"Speaking of which," Alex said, glancing up at the ceiling as an alarm started to go off. "Sounds like a bad guy needs dealing with."

Kara tilted her head, listening to the specific rhythm and cadence of the alarm. "That's not a DEO alert. That's Justice League."

"Better get going, then," Alex prodded, pushing Kara along towards the door.

"Alright, alright," Kara said, waving her arms as she jogged along. "But we are definitely picking this up again later," she finished, before using her superspeed to rush out of the compound.

…

Seriously. Why the punching?

Kara had to admit her cousin had a point as she effortlessly mangled guns and socked gang members into unconsciousness. She could still remember those days in National City when she and Clark romped through downtown, taking down robbers and car thieves and every other manner of petty criminal, but even now, despite both of them having nicknames that included the words "of Steel," bad guys still insisted on trying to punch their way past the Kryptonians. Inevitably, the effort ended poorly for them.

Once Kara had flown out of the DEO, Overwatch linked up with her official JL communicator earpiece and briefed her on the situation. A crime syndicate in Keystone City had gotten a bit too big for its britches and was attempting a brutal takeover of an impoverished section of town using an impressive array of military-grade weapons they had acquired illegally. Strictly speaking, Kara wasn't the closest JL member available, but the magnitude of the event required what Felicity coined "a Super touch."

"You know, backup'll be arriving soon if you want to save some for the rest of the League…" Felicity began.

"Nah, I think I've got it," Kara replied conversationally into her communicator, glancing idly at her chest as a grenade bounced off it. She caught the grenade before it hit the ground and cradled it tightly against her stomach, covering it up with both arms. An entirely underwhelming explosion followed a few seconds later, and she opened her arms to let the grenade fragments fall harmlessly to the ground. She then sped over to the gangster who had hurled it at her and knocked him unconscious, the man too flabbergasted by her powers to even try defending himself.

"Show off," a voice teased behind her.

Kara glanced back to see the familiar lightning-streaked red suit of the Flash leaning against a wall, arms crossed as he surveyed her handiwork. "You're just lazy," she retorted.

"How am I lazy? I just got here!"

"Exactly! How can you be the fastest man alive and still be late?"

"Hey, disaster relief supplies aren't going to deliver themselves."

"Excuses, excuses."

Barry laughed and walked over to her. "Fine. You're amazing, and I'm a slacker. Happy?"

Kara returned his laugh with a playful smile. "I don't know," she replied airily, tilting her head up as he stood in front of her. "I'm still annoyed at you."

Barry grinned as he leaned forward, cupping her face with both hands like she was the most precious thing in the world. "Really? Still?" he chuckled.

"Yup. You could say I'm 'super' annoyed," she teased, placing her hands softly on his upper arms.

Barry huffed in amusement at her corny joke. "Unbelievable," he muttered, the smile never leaving his face as Kara felt the gentle pull that brought her lips to his. They stayed in that embrace for a few seconds, happy to be with each other for the first time in weeks. When they finally pulled away, Barry told her, "I've missed you."

"I've missed you, too," she replied.

Barry's smile grew wider, but his eyes also carried a mischievous glint that she knew all too well. Before she had a chance to process this, he quipped, "By the way…," before disappearing in a blaze of light and wind. Kara briefly registered a distant smack followed by someone groaning, and then Barry was suddenly back in front of her.

"…you missed one," he finished cheekily.

Rolling her eyes and shaking her head, Kara wrapped her arms around Barry's neck to bring him close to her again.

"You know I can see you two, right?" Felicity chimed over the comms.

…

"Barry, don't you think Kara would prefer you two spend time alone in your own place?" Joe asked exasperatedly, over the sound of button mashing, as he walked through the door of his house.

"Actually, I'm having a great time kicking Barry's butt," Kara laughed, dropping her controller in satisfaction.

"What? You finished last!" Barry replied incredulously.

"Yeah, but I knocked you down to fourth," she shot back.

"Only because you threw a freaking blue shell at me."

"Hey, if I'm not getting first, neither are you." Barry responded with a glare, so she stuck her tongue out at him petulantly.

"You haven't seen each other in weeks, and you want to play video games?" Joe pressed on skeptically, hanging up his coat and putting away his shoes after having just finished his day at the police station.

"I don't have a TV at my place," Barry pointed out.

"You live in a huge loft. How can you not afford a TV?"

"Hey, that loft cleaned me out. Captain Singh hasn't given me a raise in years."

Joe turned his head to Kara, but she put her hands up defensively. "Don't look at me. I get a low-level reporter's salary."

Rolling his eyes, Joe shook his head, muttered "kids this days," and plopped heavily into his favorite armchair next to the couch. "What a day," he continued, emphasizing each word tiredly. "That gang's attempted coup was huge. No wonder Keystone called us for help in processing all the perps."

"At least Kara secured all the weaponry so you didn't have to put any officers in danger," Barry pointed out.

"Yeah, that's true," Joe conceded. "Still, I am too tired to make dinner. You kids want anything? I'm going to order out."

"Oh, no need," Kara replied brightly. "We took care of it. Dinner's almost ready," she finished, tilting her head towards the kitchen.

Bewildered, Joe glanced at his watch. "I literally saw you two barely an hour ago. How did you–"

"Superspeed."

"Heat vision."

A moment passed. Then Joe simply shook his head, got up, and headed to the kitchen. "I'll never get used to this stuff," he sighed. Kara glanced over at Barry, and he in turn glanced back at her. Without saying a word, they both dissolved into laughter at Joe's befuddlement.

…

Blearily, Kara cracked open one eye as her hearing caught the telltale chirp of two JL alerts coming from the nightstand.

She knew what they were for: a reminder that a major conference would be taking place in a couple hours and that every member needed to be near a primary League hub so that he or she could participate. S.T.A.R. Labs was one such hub, so it was no problem for her to simply remain in Central City after handling the gang business in neighboring Keystone. True, she could have gone back home, where the DEO was another hub, but as she felt the rhythmic breathing underneath her head, she was glad she'd stayed.

After catching up the night before with Joe and later Iris and Wally, who joined them for dinner, Kara and Barry had gone back to Barry's loft together. After having been separated for too long, he on a humanitarian mission and she on a DEO-organized war games practice scenario, alone time was a must. Now, the following morning, Kara was content to simply lie in bed, her head on Barry's chest as she felt his solidness against hers.

Life had gotten so busy since the two of them, along with Clark, Oliver, and a few others headed up the formation of the Justice League. Becoming an actual organization meant they were no longer accountable only to themselves and that they couldn't just be vigilantes or good Samaritans anymore. The responsibilities weighed heavily upon them all, but for Kara and Barry, they positively wrecked havoc upon their life as a couple. They spent huge chunks of time apart, they always had to keep their larger obligations in mind whenever they worked together, and opportunities to actually build a life with one another were few and far between. Advanced technology or not, superpowers or not, they weren't robots, and anyone would acknowledge there were limits to what they could or would do to make things work.

In spite of that, Kara could feel deep down that she was happy with how things were going, and she could tell Barry felt the same. Leading dual lives was practically a habit to the both of them, and in a way, as hard as the periods of separation, distance, and responsibility could be sometimes, it led them both to cherish their time together all the more. They each understood on a fundamental level how important being a hero was to the other, an insight only a select few could ever truly comprehend, and a reason they connected so well.

Besides, if they were ever desperate for a break to just be together for a bit, they could literally speed towards each other, she flying and he running, no matter where they were.

Ah, the perks of being "super." Kara smiled to herself at the thought of her and Barry sprinting at each other from opposite sides of the world, pressing her cheek softly into his chest. He began to wake up under her light pressure, and his hand sleepily drifted over to stroke the rat's nest that was her bedhead.

"Morning."

"Morning," she mumbled back, too comfy and enjoying too much the sensation of his hand through her hair to move.

"Last night was fun."

"It was. Plus, no furniture was broken this time."

A groan. "Kara, that happened once."

"Yes, and I will never let you forget it," she giggled.

Barry laughed in defeat. After a pause, he asked, with a cheeky tone of voice, "Want to go again?"

She chuckled. Typical. "You conveniently slept through the JL notifications we both got on our comms. We're due in S.T.A.R. Labs in, like, an hour and a half," Kara said.

"You realize even if we took the scenic route, we could both be there in about thirty seconds," Barry countered.

"You know how long this meeting could go," she replied, finally shifting her head to face him directly. "Do you want to face J'onn and Oliver on an empty stomach?"

"Point taken," he conceded. After a pause, he asked her, "So which one you taking this time? Food or coffee?"

Considering for a moment, Kara finally said, "Food."

"Alright, I've got coffee," Barry agreed. "Meet you back here."

In a blink, both jumped into superspeed, pacing through their individual morning routines before vanishing from the loft to grab the first meal of the day.

…

"Security's not so bad."

"Malcolm Merlyn infiltrated your Bunker, Oliver. Repeatedly."

"You should talk. Exactly how many evil speedsters have gotten into S.T.A.R. Labs?"

"Didn't the Music Meister infiltrate the DEO and then leave via interdimensional breach?"

"Okay, okay," Clark interrupted, raising his voice slightly to calm the squabbling that was starting to develop. "We can all agree that, if we're going to use our bases as Justice League hubs, we should probably make an effort to secure them."

Kara tried not to get dizzy at the array of extra screens that had been brought into S.T.A.R. Labs to accommodate all the different locations from where Leaguers were transmitting. One screen showed a crowd of people, with Oliver in the forefront and the grim, underground environment of the Bunker in Star City making up the background. In another, she saw J'onn and Alex checking in from the DEO base in National City. Kendra and Carter from St. Roch. Wally from Blue Valley. Mari from Detroit. Roy from Hub City. And so many more, from many different locations and, indeed, different dimensions. The planning alone to get everyone in on call was a feat in and of itself.

And then, of course, there was her cousin in Metropolis, coordinating it all.

"We'll start with S.T.A.R. Labs, since it's the most centrally located of our bases," Clark continued.

"Guess Central City lives up to its name," Barry quipped, sitting in a chair across the room from Kara.

"We'll probably need some help," Caitlin pointed out, sitting in the center of the semi-circle console in the middle of the room. Since the formation of the League, Caitlin had taken a leading role as the primary S.T.A.R. Labs point of contact. "Cisco's got a lot going on already, patrolling the multiverse with Gypsy."

"Yeah, I'm stretched a bit thin," Cisco agreed from his own screen.

"I can come help," Felicity chimed in, her blond head popping up behind the heavily-muscled, leather-clad figures of Team Arrow.

"Having a military perspective might help as well in tightening up security," J'onn said. "Alex will join you." Beside him on the screen, Alex nodded her head.

"Should I head back to National City, J'onn?" Kara asked.

"I think we'll be better off with you staying in Central City for now," Cisco interjected. "Implementing the security upgrades we've drawn up could require heavy lifting. Like, literal heavy lifting," he clarified. Kara nodded her agreement, shooting a small smile in Barry's direction, which he immediately returned. Neither would begrudge the additional time together.

"Sounds good," Caitlin agreed. "I'm going to get Harry from Earth-2 here as well to consult on how we handle the particle accelerator with these new upgrades. The only one who knows that thing better than Harrison Wells is…well, Harry Wells."

"Okay," Clark said. "We'll use S.T.A.R. Labs as our test example and apply the lessons learned to secure our other bases. Keep us informed."

"Will do," Caitlin confirmed.

"Right. That concludes our meeting. Thank you all for conferencing in. We'll be in touch soon." With that, Clark cut his video feed, and one by one, the rest of the screens went dark as well.

"Well, guess we've got a lot of work to do," Barry said.

…

Over the next week, S.T.A.R. Labs went through a badly needed major security overhaul. The amount of work required would normally take a fully human crew months to complete, but the technical team of Caitlin, Felicity, Alex, and Harry found having the Girl of Steel and Scarlet Speedster around quite handy.

"Yeah, yeah, just hold that steady," Alex muttered to Kara on the roof of the lab, a screwdriver held between her teeth as she fiddled with wires on a large surveillance turret that Kara was holding in place with one hand.

"Right, we'll need cables run along here, here, and here," Harry pointed out, back hunched over a schematic of the room they were updating. A rush of air blew around the room, and when Harry straightened up, Barry was standing behind him, all the cables in the room already in place and a politely inquisitive look on his face, waiting for his next task.

"I cannot believe you've all set up literally nothing," Felicity said for the fifth time as she and Caitlin sat side by side at the semicircle console in the main lab, updating defensive protocols to be applied across the lab.

"We get it Felicity," Caitlin intoned.

"No security."

"We know."

"No alarms."

"We know."

"Nothing at all stopping someone from walking through your front door."

"Infiltrated by three evil speedsters. We already covered this, Felicity."

"I mean, sure, Merlyn's gotten into the Bunker, but he's League of Assassins. At least we have a secret elevator entrance! We're underground! No one else knows we're there. This place," she said, building up steam as she actually stopped coding to throw her arms up, indicating the entirety of S.T.A.R. Labs, "is out in the open! It's been out in the open for forever! I could infiltrate this place."

Caitlin sighed. "Felicity, are you here to help or are you here to be outraged?"

Felicity paused, glancing at her hands, which were still thrown up in the air. She lowered them slowly, a bit embarrassed. "Sorry," she said, clearing her throat. "I'll stop." She resumed her coding.

Caitlin laughed, sure that was not the first time someone had brought Felicity's own theatricality to her attention. "It's nice having you here to lend a hand," she soothed. Felicity thanked her with a smile, a smile that quickly disappeared as she jumped from a loud noise suddenly sounding off.

"I stand corrected," Felicity said, checked her console. "You do have alarms."

"Unfortunately, that usually only means one thing," Caitlin replied ruefully. She pressed a button on her own side of the console to tap into the audio system for the lab. "Everyone get down here. There's trouble in the city." Within moments, Kara, Barry, Alex, and Harry were at her side.

"What've you got?" Barry asked her. In response, Caitlin brought up live camera footage of downtown Central City, allowing them to witness scenes that were chaotic and, frankly, bizarre.

Seemingly everyone had emptied out of their cars and all the nearby buildings. Half of the people were punching the living daylights out of each other, yanking each other's hair, and generally pummeling anyone they could reach with shopping bags, cell phones, umbrellas, and keys. The rage and aggression in their faces were almost feral in nature. The other half was cowering on the ground, under idling cars, or against the walls of buildings, making no effort to escape even when the brawlers seemed to be blatantly ignoring them. It was as if they were paralyzed with terror as they lay prone on the ground, curled in the fetal position, or rocked back and forth, a reaction among too many people that simply didn't match the situation the S.T.A.R. Labs team was witnessing.

"What the…?" Harry couldn't finish his question, expressing the confusion on all of their faces.

"I've got a really bad feeling about this," Caitlin muttered.

"Felicity, can you get eyes on anyone suspicious? Anyone who might have caused this?" Kara asked.

A flurry of typing. "No," Felicity admitted, shaking her head. "There's just too much mayhem. It's impossible to know where to look or what to look for."

Now all business, Barry pulled his cowl over his face, adjusting the eyepieces so that it fit snugly. "We'll have to figure it out then. Stay alert on comms. Supergirl, I could use a hand."

"Whatever you need, Flash." A blink, and both superheroes had zoomed out of the lab.

…

"What…is going on?"

Kara and Barry stood flabbergasted at the edge of the scene in front of them, momentarily unable to process the absolute chaos. Some people indiscriminately beating each other into oblivion. Other people screaming their heads off, folded into a ball, or clutching desperately to a wall or the ground as if the world would disappear at any moment. There wasn't any single thing to which the people were reacting. It was simply anarchy.

"Would they…would they stop if we separated everyone?" Barry asked dubiously, indicating the brawlers. His answer came when one particularly nasty fight in front of them between two women got broken up as a man from a different fight was bodily tossed between them, forcing them apart. Instead of reengaging, the two women turned and started picking fights with new partners.

"I'm guessing 'no,'" Kara quipped, unnerved.

After a couple more seconds of observation, Barry said, "We might have to just knock everyone out and hope they come to their senses when they wake up."

"With what? Some sort of sleeping gas?"

"I was thinking a more direct approach. We're both fast enough that we might actually get through this crowd."

Kara sighed, catching Barry's drift. "I really hate the idea of having to whack all these people in the head."

A shrill scream turned both of their heads, and they caught a woman chasing a man down the sidewalk while swinging an antique lamp on a chain like a flail and screaming bloody murder.

"On the other hand…" Without finishing the thought, Kara and Barry burst into action. Kara sped up to the woman, caught the lamp in one hand, and lightly smacked the woman in the forehead with an open palm. The woman crumpled to the ground unconscious at Kara's slight application of superstrength. "Sorry," Kara muttered, wincing slightly. Turning around, she saw Barry similarly handle the man, who also collapsed to the ground.

"We might as well split up," Barry huffed, dragging the man's body to prop up against the side of a building, relatively out of harm's way. "You take care of this side of the city. I'll go to the north side."

"Got it. We'll meet up after everyone's down and try to figure something out."

"Copy that. See you soon." Kara's hair flipped momentarily in her face as Barry zoomed off. As she turned to deal with the riot in front of her, her hair flipped in the opposite direction as Barry reappeared in front of her.

"Almost forgot," he said, smiling, before giving her a quick peck on the lips. Then he rushed off again.

Dork, she thought to herself, a smile refusing to leave her face as she smacked humans into dreamland.

…

Soon, using her superstrength and superspeed, Kara had arranged rows of unconscious people on the street, bruises blooming on their foreheads and either a headache or mild concussion in their immediate futures. She felt bad inflicting these injuries on the mass of people, but as she had already had to stop one man from gouging out a woman's eyes with his keys, another from kneecapping another man with a lug wrench, and a woman from strangling her opponent with a belt, she figured this was the lesser of two evils.

The brawlers on her side of the city taken care of, Kara turned her attention to the rest of the people seemingly paralyzed, unwilling or unable to move. She moved from person to person, trying to encourage, reassure, cajole, and otherwise convince them that there was nothing threatening them, but to no avail.

"You don't have to be afraid," she tried again, moving to a man hugging his legs, his face buried in his knees. "There's no danger anymore," she said, placing a hand gently on his shoulder. She heard some loud, almost exaggerated sniffing, and then the man lifted his eyes, locking her in his gaze.

"Are you sure about that?" he asked, in a taunting voice. His eyes glowed red.

Kara tried to look away, but she lost herself in the man's gaze. Unblinking, she felt an indescribable, violent fury overcome her senses. Her body experienced a massive jolt, like every one of her muscles had been shot through with adrenaline, her primal instincts going into flight-or-fight mode, except that "flight" was the further thing from her mind.

She blinked. The man was gone, but she saw all these people cowering on the ground. These whining, sniveling weaklings, so incapable of fending for themselves that they crouched in fear. Didn't they know who she was? Did they think she had time to hold their hands and give them hugs? She was Supergirl, she was more important than all of them combined, and they should be punished for wasting her time like this.

Standing up, fists clenched, Kara stalked to the nearest human, curled up in a heap and not even registering the honor he should feel at having his existence snuffed out by a goddess. It was time for the humans to learn respect. Cocking back her fist, Kara prepared to turn him into a greasy stain in the pavement.

No!

Kara's fist stopped halfway to its target, and her eyes widened. "What's…what's happening?" she stammered to herself. Stumbling, Kara backpedaled away from the oblivious civilian she was just about to actually murder, shaking her head furiously. Her body trembled, still shot up with this ferocious anger that she couldn't explain, her pulse racing, but she forced herself to her knees, hands grinding up the pavement beneath her until her fists were filled with gravel. Her eyes burned, as though she could literally feel them glowing red in a sinister way that had nothing to do with heat vision.

Desperate, she raising a shaking hand to the JL communicator in her ear. "Flash? I…I need help."

Static.

"Flash? Overwatch? Is anyone there?" she repeated urgently. Still, all she heard was static.

"Aww, is the Girl of Steel all alone?"

Still on all fours, Kara turned her head to the sound of the voice, and her stomach churned at the sight of the leather-clad blonde stalking towards her. "Psi," she muttered.

"The one and only," Psi taunted. "I thought you can leap tall buildings in a single bound. To me, it looks like you've fallen and you can't get up."

Too much. Everything was too confusing to process, and Kara felt her desperate grip on herself slipping. The red burning sensation shot through her eyes again, and she got to her feet. "You picked the wrong time to test me," she growled.

Psi laughed lightly in response, which enraged Kara even more. "Actually, I'd say this is the exact right time."

Unable to hold back any longer, Kara's body left the ground, aiming to flatten the bothersome meta, but in that instant a pulse shot from Psi's forehead and sent her crashing back down to her hands and knees. Immediately, she felt another jolt through her body, but now her instincts swung painfully and drastically in reverse, now squarely in "flight" mode rather than "fight." Her vision clouded, her heart was threatening to burst out of her chest, and she felt as if pillows were clamping over her ears. Her brain, so full of aggression and rage just moments before, now screamed at her to get up and run, but at the same time her limbs felt glued to the concrete underneath her. She got the vague sense of laughter somewhere above her. Psi, maybe? Kara didn't react. She couldn't.

In her mind's eye, people were shouting, running away in fear. She tasted the acrid smoke of burning cars, listened to the chaos of panicked steps crunching broken glass underfoot.

"Look at that city. They worship me. And those who don't, will."

Cat Grant's screams echoed through the night air as she plummeted, seemingly to certain death from the rooftop of CatCo.

"True power, Cat, is deciding who will live and who will die."

She saw Alex thrown bodily through the air, her trajectory only stopped by the unyielding surface of a car door, and heard through her superhearing the unmistakable crack of a bone breaking.

"Deep down, you hate me."

Her potential for anarchy, for absolute power, for ruthlessness. For evil. What if no one could stop her? What if she couldn't stop herself? The panic swirled faster and faster inside her mind, completely paralyzing her limbs in terror. A disconnected part of her brain, though, registered that something else required her attention, and she raised her head, only to see a blurry figure through her tunneling vision.

"Well, it's been fun," Kara vaguely heard. A sudden wave of weakness and nausea overcame her, and a flash of green exploded in front of her eyes. A stab of pain, then darkness.

…

Author's notes: In my head, this story is a spiritual sequel to my other story, "World's Newest," but I won't be referring to anything here that's specific to World's Newest. I consider that one more as the history and context for Kara and Barry's relationship and the Justice League's formation, but it's completely unnecessary to follow this story.

Felicity's complaints about the S.T.A.R. Labs security are taken from The Flash 4x05, "Girls Night Out."

Some of Kara's thoughts are direct dialogue from Supergirl 1x16, "Falling," and Supergirl 2x02, "The Last Children of Krypton."
