Work Text:

You were a shadow. Well, honestly, you don’t know what you are. You were born human, yet was abandoned due to your anomalies. You were born pitch black, it was like the shadows swallowed you whole and instead of crying, you came out of your mother’s womb laughing. Your ‘parents’ immediately dumped you somewhere deserted and after hours of crying, you were sucked in a vortex like circle where you spent the first years of your childhood.

That was until a certain, bald headed Luthor ripped through your pocket dimension. You were a teenager, basically a child, he abducted you without a word and experimented on you. They kept you in an all white room accompanied with blinding lights, keeping you from the shadows at all times.

They experimented on you, frustrated because you failed all their exams, you had nothing in your DNA that separates you from humans, nothing was wrong with you at all. That went on and on, until a containment breach happened and all lights shut off. You managed to rip whatever wires they attached to you and immediately blended in with the shadows, incapacitating every scientist and guard you come across.

You stopped in your tracks when you spotted the youngest Luthor crying, you knew her, somehow. The shadows told you about her, and now they were urging you to save her.

And so you did, you made sure she was safe before creating another pocket universe, leaving her behind with only memories of your glowing crimson red eyes.

Creating your own dimension sapped almost all your energy, so much that you had to remain unconscious until you were capable of opening your eyes. Unbeknownst to you, a whole lot has happened since you were asleep. And the minute you opened your eyes, your thoughts immediately drifted to Lena.

Having mastered your powers prior to your imprisonment and it developed while you were in a coma like state, you started to branch out, looking for the dark-haired goddess that you were attached to. Only to find out she was… Well, married… To a blonde alien.

“The irony.” You laughed, making yourself breakfast in your pocket dimension.

The shadows told you that it has been 20 years since you escaped, since you slipped into a coma. And during that, the shadows took it upon themselves to protect you, creating a huge ass house inside the pocket dimension you made, using the TV they made, you were able to catch up and keep up with what’s going on outside your little world.

“Like I said, I’m not a reporter” The blonde alien says- ah, her name was Kara. You were just used to calling her blonde alien.

“Could’ve fooled me” Lena grins, which made you smile. She has grown into a fine young woman.

You shoved a fry into your mouth, re-watching the first time the married couple met, laughing at each time they go into this shy, awkward atmosphere. They’re just too adorable.

You were currently watching one of your favorite scenes when the screen flashed red before switching into a different scene. You immediately sat up, your shoulders tense. It was a live stream. This was currently happening now. You were watching Kara Danvers-Luthor get thrown around like some ragdoll while Lena Danvers-Luthor gets hold at…spear-point? Honestly, what is with aliens and their plasma powered pointy sticks.

“I’m gonna have to help them aren’t I?’ You sighed, asking the shadows, watching them slowly form into a humanoid form.

“I’m afraid so, Your Highness. It’s still completely up to you. However, I think you already know what to do.” The humanoid shadow : who called themselves Kage told you, their facial expression mimicking that of a “smug human” as they call them.

“Fine, Fine.” You huffed, dragging your finger down, allowing you to open a gateway from your small world to the gruesome scene. The shadows enveloped you, allowing you to move swiftly, as long as you avoid overly bright places such as fires and streetlights.

With Kage running beside you, the shadows liquified, allowing your body to have a sort of, liquid protection layer. You created a puddle of dark sludge, jumping in it, trusting the shadows to clean your mess.

“Kage, make me a gateway to that spaceship above, and stay here. Catch Lena when she falls.” You ordered, swimming up the shadow sludge.

“Yes, Your Highness.” Kage answered

“And don’t call me your highness!” You screamed, finally reaching the gateway Kage opened for you.

You poked your head out to observe the ship, this isn’t the mothership, it’s likely only the first wave and the rest of the ships are heading this way at a much slower pace. You manipulated the shadows in the ship, trapping the aliens inside silently. You watched carefully as the alien beside Lena is shouting something, probably an order, when he noticed no one was responding, he turned around, only for your fist to come in contact with his face. A loud crack resounding in the ship, which was followed by a faint splat. The commander alien fell to his death.

“…That was not my fault.” You grinned at Lena, your expression turned soft as you found yourself in front of the dark-haired beauty.

“Hi.” You said timidly, before hardening up.

“Do you know how to fly an alien ship? Nevermind, I know you do.” You say, walking fast to the cockpit. These ships are strangely like an airplane.

“Wait. Hold on! Have we met before?” Lena rushes after you

“Maybe. Now, maneuver this ship to that giant thing there and save your wife.” I push her slightly

“But that’ll cause destruction to the city as well!” She reasoned, and you smiled, knowing her wife was her priority but the city is what Kara swore to protect, and Lena took it upon herself to do so as well.

“Fine then. Down you go.” You say smirking, creating a sludge portal from beneath Lena’s feet, knowing Kage would take care of her, hearing her surprised scream made you giggle lightly.

“And now to save the other half.” You jumped from the ship, free falling down and silently thanking they chose to attack at night.

Still using the armor you made earlier, just making it slightly bulkier, you came from behind the giant metal thing. Is this seriously an alien inside a giant robot? Is this race this insecure? Geez.

You managed to flip your body, feet first and used your momentum to successfully kick this metal thing’s head clean off it’s body, small sparks of blue electricity escaping from the cut wires. You knew that you’ll get hurt once you land on the surface, half because that robot is so tall that the drop height is painful and you might end up with shattered legs and the other half was because there are DEO agents pointing their gun at you, including Alex Danvers herself.

So you decide to keep yourself safe by making the sludge portal right where you’re about to fall, successfully avoiding the gunshots of the Agents. After falling right in, the portal immediately closes. You sighed, how the hell would you get the other Luthor with her sister keeping watch of her? Get under her and make her fall into the sludge, and also putting yourself into the DEO wanted list.

Well, it’s worth it, if you see Lena smile while Kara limps to her, you’ll probably slip into another coma from heart palpitations.

So you did exactly what you planned, opening a sludge right under Kara, making her fall down easily. But what you didn’t expect is Alex rushing in and taking a hold of Kara’s hand.

“Seriously?” You asked, exasperated, to which Alex just grunted

“Fine. You’re coming with.” You say, feeling your power grow weaker by the second, too much light was being pointed at you.

And so you pulled Alex down as well, chuckling lightly when you see the sisters hold their breaths.

“It’s not water, if that’s what you’re thinking. It’s just shadows imitating water. You can breathe here, don’t worry about it.” You assured them with a gentle smile, to which they shot you a glare which says: “We don’t trust you.”

“Fine then. Hold your breath.” You sassed, taking a hold of their hands before teleporting to where Kage and Lena was, Your mansion.

Arriving at the mansion, the sisters stumbled, dizzy with the teleporting, you also raised your eyebrows at a calm Lena drinking wine with Kage.

“…I expected you to be a lot more panicked.” You say slowly, accepting the wine from Kage

“I was, until I remembered who you are.” She says, as she sips her wine.

Alex stared at Lena with a shocked look on her face before glancing to you and your…companion.

You were wearing a modern look that screamed intimidating, like you demanded respect as you gave them your respect as well. It irked Alex how normal you looked, besides the glowing red eyes, despite this situation being absolutely not normal. Your companion however, was dressed like a butler in the Victorian Era, their face void of facial features besides the bright white eyes and a sharp grin, showcasing a set of teeth that was bound to be nightmare material for kids and adults alike.

“Okay! What the hell is happening here?” Alex raises her voice, breathing heavily.

“Let’s tend to Kara’s wounds first.” You offered your hand to Kara, to which she hesitantly accepted, you hovered your hand to hers, watching silently as the shadows healed her, seemingly eating away her wounds. You looked up to her, and she had this adorable look of fascination.

“It’s not really as magical as you think. The shadows on your body just speed the time up. For example-” You pointed to a rather large gash of wound on her collarbone, watching as the shadows covered her wound and then return back to your hand when it’s time. “-they just speed up the time on the affected part, so that your recovery is instantaneous.”

“Cool.” Kara says giddily, turning back to Alex who still had a weary look on her face.

“Relax. I’ve been existing since uhh… I actually don’t know. A long time. If I wanted to kill or harm even a single human, I would have done so by now.” You said to Alex, offering her a glass of whiskey

“No thanks.” She declined

“Right. You don’t trust me.” You pouted, which made Alex take a step back. You just defeated a creature that even Supergirl can’t defeat in one strike and now you’re in front of her pouting.

“…No, I’m still on duty.” She says in her best director voice.

“Right, Director Danvers.” you nodded, plopping the glass on the bar table, turning to the married couple who were fussing over each other.

“You guys can stay for dinner if you want to.” you hummed, wearing your apron and walking to the kitchen.

“Y/N.” Lena called out before you went in.

“Yeah?” You looked over your shoulder, surprise written all over your face. She remembers you?

“Thank you. For saving me. Twice.” She says, with a slight smile.

“No problemo.” You smiled sweetly before heading to the kitchen.

“Ms. Y/LN makes the best meals. Please do try to stay for dinner. She hasn’t had anyone over for at least 20 years.” Kage explains, leading the trio to the dining room.

“How so?” Lena asks, seemingly the only one interested, Kara was busy looking around the room and Alex was standing in the corner with her arms crossed.

“She has been on a coma since she saved you, Ms. Danvers-Luthor.”

“Enough with the sadness Kage, geez.” You say suddenly, emerging from the kitchen with four plates of steaming hot food

“That was quick.” Alex commented, thinking that you must’ve planned this, given how there’s already prepared meals for them while Kara just looks happy to be given potstickers.

“Time moves differently here. In fact, I can manipulate the time here. Only in this dimension though. In the surface, only a split second has passed, and here, it’s been 30 minutes.” You explained, sitting down to eat.

“I don’t own any poison by the way. I find it incredibly tiring to go up to the surface to buy groceries, so I just let my shadows do it for me.” You nonchalantly say, noticing how Alex stared at her food wearily, spooning food into your mouth after you said those words.

“Even then, We really can’t stay-” Alex’s words were stopped when she saw Kara started eating

“…We really have to go” Alex continued with a stern glare to Kara

“I’ll agree to containment if you eat.” You say easily, munching on your steak

“…Fine.” Alex grumbled, you always did find it cute when Alex tries to be tough. She has more similarities to her golden retriever of a sister than she’d like to admit.

After Alex sat down, you all continued eating silently, at first anyway. Lena initiated the conversation and soon Kara followed, her sister asking a few questions here and there. You were smiling happily, having gotten your life-long wish… Well, the life long wish being the 10 months you’ve been awake.

You hummed to yourself, talking with them a bit more, congratulating Lena on her recent achievements and she thanked you for that, chuckling at Kara’s antics that mostly consisted of her boasting about her wife’s “geniusness” while Lena raised her eyebrow at her, stifling a smile, to which you silently cooed at.

You seemed contented, beaming happily as you talked to her sister and her wife, Alex noted. She also watched your body movement, you had these small mannerisms that sometimes has her reaching down for her hand held gun, but always turning up to be a false alarm. She can’t help but become paranoid of you, she knew from experience that red eyes almost always meant danger. That’s what she told Lena when she told her of that child…

Alex’s eyes silently widened for a bit, could you possibly be that child that Lena asked DEO’s help on finding? Her eyes flitted to your left arm that was conveniently right in front of her, if you were who she thinks you are, you should have a long scar from your left shoulder to your forearm from one of Lex’s tantrum, however she mentally facepalmed herself when she remembered you were wearing a long sleeved shirt. It made perfect sense, how Lena knew you, how Kara seemed comfortable around you when she knew for a fact that her sister haven’t even met you yet. Alex is happy Lena found you, however, she still needed to bring you in, it’s protocol. Alex reasons with herself.

Meanwhile, Kage is silently standing on your right, they’re silently watching the scene in front of them. You looked happy. To the surface-dwellers, you looked happy. But to them? To your shadows? They know you’re not. They are a part of you, They are connected to your very soul, they probably know you better than you know yourself, (Which you think is neither an advantage or disadvantage, you just asked them to not be too nosy with your thoughts unless necessary).

You’re anxious. You just agreed to being caged once again. You knew that they weren’t as harsh and brutal as Lex, but you were scared nonetheless. This was your first time going up to the surface for long periods of time and you were going to spend it trapped in a extremely bright, white colored room. You’re terrified.

Once dinner was over, Kage and Alex looked at you with knowing eyes.

“Let me just get my stuff.” You mumbled, placing a hand on Kage’s shoulder to prevent them from glaring and possibly ripping Alex’s head from her body.

“You don’t have to do this. I could kick them out.” Kage pleaded, feeling your fear.

“I don’t break my promises Kage. Besides, I’m strong enough to go outside, you said it to yourself.” You say, staring at a journal you opted on giving to Lena, or Alex. You don’t really know.

“But-” They tried stopping you as you walked to the door, bag in hand

“You’ll be there for me when I need you right?” You peeked over your shoulder to look at Kage’s white eyes, the only color that’s not black on their whole body

“Of course.” they nodded

“Then that’s all I need. Take care of this place for me, make sure there’s no dust when I come back.” You grinned at them, the implied promise of coming back lingering in the air.

“Tsk. When have I ever missed even a single chore?” Kage scoffed

You just smirked, leading to Kage glaring at you.

“Asshole” They whispered, pushing past you and huffing as they moved to clean the table from your dirty plates.

“Kage will be staying here. I’ll be the only one accompanying you to the surface. Before I forget tho-” You took out the leather bound journal, “-This was all of Lex’s findings about me, also some things that I found out about myself, I wrote it there.” You gave the journal to Lena.

“It’s legally yours, I just stole it.” You grinned mischievously as Lena scanned through the pages, eyes glimmering with unmistaken nostalgia and delight at the new information, but also distaste at seeing her brother’s handwriting.

“Right. We should be going. Apparently 30 seconds of Supergirl and the Director of DEO missing is incredibly dangerous.” You chuckled, mocking Alex lightly before making a portal straight to the DEO headquarters, dead smack in the middle of it. Luckily Alex was quick on putting handcuffs on your wrists and leading you to one of the cells or else you would’ve been either in the bottom of a dogpile of sweaty and musty DEO agents or staring down on a barrel of a gun.

Alex seemed to loosen up a bit, telling you that they only need proof and confirmation that you are not a threat to humanity and they can let you go. You just shrugged her off and laughed, telling her that as long as you have at least 30 minutes of pitch black darkness in your cell once every week, you’re going to be comfortable as too much light was damaging to your body.

Thankfully, due to Lex’s journal, which you stole, the amount of tests that they performed on you were lessened. Lena did her best to visit you, telling you stories of both the past and present, exchanging opinions about certain things, and asking for your help on some of her “asshole business partners” problem. She also brought chess boards whenever she can, laughing at your annoyed expression since you never understood chess no matter how much she teaches you.

On times where Lena couldn’t go, Kara would drop by, chatting you up until Alex barges in and drags the Kryptonian off the best that she can, which was funny to look at. An older Earthling sister dragging a begging younger Kryptonian sister away from the chuckling Earthling who had the ability to control shadows.

A few weeks later, you were given a pass to spar with Kara, on a 40% kryptonite room, which was hilarious because you just kept trapping Kara in your powers while she did her best to fly out and whine at you whenever you did that.

“That’s not fair!”

“I don’t have super strength nor do I have fighting skills. I have fragile Earthling arms! See?” You swayed your arms around, emphasizing your point.

The next day, Kara had to tend to some minor alien threat and so you were faced with the ever intimidating Director Danvers, who defeated you in 6 minutes and 48 seconds despite you using your powers.

“I give! I give!” You whined, pouting

“You have to get a lot better than that if you want to fight alongside Supergirl” She stated, drinking her water

“Wait, What?” You beamed, rushing to put your face directly in front of hers, which led you to being flipped and landing on your ass.

“I’m gonna fight WITH Supergirl?” You happily said, rubbing your sore ass cheeks

“Not with your fragile Earthling arms.” Alex smirked as you gave her a playful glare, charging at her to continue your sparring.

Up until now, you still haven’t been able to defeat Alex.

A year of training and learning how DEO works, you were finally allowed on a mission with both Alex and Kara. A broken nose, bruised knuckles and a black eye later, the mission ended with success, which led to Alex giving you freedom to go back to your own pocket dimension and an invitation to the much awaited superfriends game night. Which you agreed to, happily. And you will never forget that first game night you attended.

You were painfully awkward, you only had interacted with Alex, Kara and Lena before, only talking to Winn when needed. But with a welcoming atmosphere, you quickly became comfortable, ensuring your spot in the “Superfriends” as Winn called them. You drank, laughed and played games together, making sure that Lena never plays monopoly since she’s too good at it and also making sure that Lena and Kara are never team mates at charades since again, they’re too good at it. You only left when you were forcefully dragged by Kage who appeared out of nowhere, claiming that you need to recharge for tomorrow’s shenanigans, a small smile on their face when the superfriends were merely startled but not afraid of their appearance. (They also swatted James and Winn’s hands when they tried to touch them)

Since then, you never missed a single game night. Which was probably how you ended up like this.

It wasn’t a secret that you adored the couple more than you’re supposed to. I mean, how could you not? They would often invite you over to their place to watch movies, drink wine and cuddle, claiming that you were warm and comfortable to sleep on. They also shielded you from the media when you first showed up as Supergirl’s ally. You once had a nightmare on your first few weeks in DEO containment and Kara’s worried face was the first thing you saw, Lena following in shortly after Kara called her and together they comforted you in the best way possible, cuddling and just generally distracting you from your nightmares.

But you knew exactly when you started seeing them in a new light. It was the fifth game night you attended, Lena paid all of you 15 bucks just to let her play monopoly and Charades with Kara. You all agreed in a heartbeat, 15 bucks is a lot of money.

You all started with Monopoly, no surprise, Lena won with a smug look on her face, but while you were playing, Kara was subtly helping you win, while Lena laughed as she took all your properties, which made you pout each time, making Kara sling her arm around you as she squeezed your pouting face, only stopping when you swatted her hands away.

But, what sealed your fate as the “Lover of Supercorp” (You smacked Winn for calling you that but then everyone started teasing you with it and you couldn’t do anything but accept it) was probably the moment where Alex caught you blushing.

“Y/N? Can you help me with this please? I’m trying to figure out a way for us to access your pocket dimensions.” Lena asked you, her bottom lip jutted out, while Kara was beside her, puppy-eyed

“…Why?” You ask, suspicious with what they are planning.

“Are you planning on using my pocket dimensions to go to Paris? I tell you, when you get there, you’ll be vomiting all over the streets.” You crossed your arms, stopping yourself from cooing and giving in.

“No, but France does sound good.” Lena smiles

“Still, my answer is no.” You moved to put your hand to the door when you’re suddenly pulled into an embrace, then into another. You’re sandwiched between a blonde goddess and a dark-haired goddess. Your eyes went wide. Even if you’re in an empty conference room, you three were still in DEO and you were still on duty.

“Uhm” You stuttered, your brain momentarily shutting down

“Please?” Kara whispered, once again using her puppy eyes

“Oh fuck it. Sure.” You exasperatedly said, disliking the way your stomach was being trampled on by literal titans or the way your heart was pounding against your ribcage, begging to be let out so the couple could hold it in their hands

They cheered and the couple walked out of the room, smiling, animatedly talking about what possible dates they could go on with your portals, leaving you in the room, swooning, with Alex walking in to check on you.

“Are you blushing? I didn’t know shadows could blush.” Alex commented, seeing the black dusting your cheeks and ears, blocking out the light that’s shining brightly at your form

“I wasn’t!” You denied, finally getting rid of the shadows that were covering your face

“I’m telling Kara and Lena.” She says, turning around

“ALEX NO!” You stopped her, the shadows returning to your cheeks

“See! You’re doing it again!” She points out, touching your cheeks and shivering at how cold they feel.

“Tell them and I’ll tell the new girl.” You smirked when it was Alex’s turn to blush bright red, her cheeks warming up.

“Oh fine.” She grumbled, stomping lightly to the command center as she monitored some potential threats, mumbling about you being a stupid oblivious idiot.

The next few weeks consisted of you training and getting into missions while squeezing in Lena’s little interdimensional project, teasing Alex with her crush on one K. Olsen and game nights. It was then you realized that, you haven’t been home to Kage for a while. Deciding to stop by and recharge, you opened a portal to your mansion and immediately felt like something was wrong.

With your hands forming small bullet-like shadows, you entered your mansion, dropping the shadow bullets when you were bombarded with color. Whoever broke into your house, they definitely painted the living room walls from their dark violet to a dark red with royal blue accents. The colors reminded you of-

“Oh! You’re home early!” Kara exclaims, rushing to you in superhuman speed from the kitchen?

“Kara? What- How? When-” You sputtered out questions, so utterly confused with what’s happening.

“Turns out, the project I was working on finished earlier than expected, and we decided to give you a little reward for all your hard work.” Lena’s words was accompanied by the clacking of her heels.

“Lena?” You muttered, drowning in her intense green eyes. You just stand there for a while, holding Kara’s hand affectionately while staring at Lena’s eyes, watching her as she visibly struggled getting something out of her system. She turned to Kara with pleading eyes, which made you turn to Kara with a confused look.

“Ahm. Well, You know. We uh, We’re married.” Kara started, you chuckling at her words

“Yes, I am aware.” You tried to stop, and when you didn’t, you felt Lena pinch your side, which made you yelp.

“Well, we uh-” Kara turns to Lena for help, while you just smiled warmly at both of them

“We like you.” Your eyes widened as you took a step back from them.

Are you dreaming again? Are you hallucinating? You secretly pinched yourself, and flinched when you felt pain. Yep, this is reality.

“Are you- You’re not joking are you?” You pleaded with them

“No! Why would we?” Lena steps closer, claiming your right hand as Kara claims the other.

“I don’t know, you’re both amazing. Hell, Kara is literally Supergirl and Lena you’re-” Your insecurities was silenced when Lena placed her lips onto yours, effectively shutting you up.

You stood there for a second, once again unsure if this was reality. You felt Kara’s hand tightens her hold on yours as you responded to Lena’s kiss.

You knew Lena was never good with being vulnerable, much less voicing out her emotions. But you felt your heart clench at the emotions being poured into your kiss. You moved the hand holding Lena’s to her waist, as you held Kara’s hand tighter, if that was possible, pulling them both closer to your body.

Kissing Lena was ethereal, passionate and breath-taking. Everything she couldn’t say, she says with her kisses. You feel her adoration, her love but also her insecurities, her fears, something that you want to love and kiss until they vanish. Kissing Lena felt like winning. Kissing Lena felt like you could take all of the world’s problems and punch them into oblivion. Kissing Lena felt like drinking a cool drink in the hot summer. You loved it. You love her.

Lena slowly pulled away from you, catching her breath as both your chest heave, large smiles plastered on your faces.

“Hi.” You say, making her giggle

“My turn!” Kara says, pulling you to her, slowly leaning in to kiss you.

Kara’s kiss was slow, passionate and gentle. You felt her love, her adoration, her comfort but also her fears, something you want to disappear for a long time. Kissing her felt like travelling into multiple universes at once. Kissing her felt like sunshine and rainbows, but also of storms and hurricanes all at once. Kissing Kara felt like drinking hot chocolate while in the middle of a freezing winter. You loved it. You love her.

You’ve imagined kissing them on multiple occasions, In conference rooms, In stakeouts, In boring meetings. But those imaginary scenes never held a candle to actually kissing them.

Kissing them felt like home.

You’re finally home.

“So, I say, You’re officially the Lover of SuperCorp huh?” Kara teased after she pulled away

“I’m pretty sure she already was ever since she first met us.” Lena shot back, gripping Kara’s hand and grinning happily

“Ugh.” You groaned, throwing your head back, letting them lead you to the kitchen where Kage was setting the dinner table, winking at you.

Who knew that being a friendly shadow led you home into their arms?

Certainly not you.
