Winn

For Winn Scotth, the concept of family had always been something abstract, until he met Kara Danvers.

Sometimes, more often than not, Winn forgets that his last name is not Danvers. It's weird if you stop to think about how long he's been in love with Kara, but now that the dust has settled and they reached the best friends forever stage, he feels a bit more comfortable thinking of her as family. That word with Kara also means that you acquire a whole package of a lovely mother, an alien dad, and an overprotective sister, who might take her role too seriously sometimes.

Winn doesn't know how it happened, but one day he realized that Alex had taken him under her wing, like she once did with Kara. It doesn't matter that he's a grown adult that doesn't need to be lectured every time he does something stupid, Alex will smack him and frown until Winn admits that he's wrong. He's not sure why but, for some reason, Winn loves that he's important enough for someone to scold him like that. He loves even more the way Alex looks at him every time he does something extraordinary, like she's really proud of him.

He loves Kara, a lot, but Alex is the one who makes Winn feel like he finally belongs in a family. And that feeling has only increased since he joined the DEO. Now he really enjoys his job and feels appreciated for everything he does, even if it terrifies him from time to time. Alex was the first one to trust him and ask for his help with DEO matters, and she's been there by his side at every step of the journey.

He understands now what family means. It means love and support, loyalty, and strength. It means standing in the line of fire to protect the ones you care about. It's all the things that Kara's family crest stands for. But it's also everything that Alex fights for, and that scares him, because, despite being Supergirl's sister, she's not impervious to bullets.

That thought has crossed his mind more than once, and prove of that is the hidden file on his computer called BD. Every time Alex comes back from a mission injured, that file is the first thing Winn opens when he arrives at home. He'll never tell James about it, but Guardian's suit was a child's game compared to what he's been working on. And that kryptonian thing? A joke. Alex deserves something beautiful, something that would allow her body to move without restrains, but that at the same time could protect her, maybe even give her own abilities on the field a little burst without the need to wear something that could potentially hurt her sister.

Speaking of Kara, he still needs to consult her about an addition to the suit, because Winn thinks it should be there, but he doesn't want to overstep. That is, of course, if he decides to tell anyone about his project. Winn isn't really confident about how Alex would react if he ever gives the suit to her.

"When you stop daydreaming about whatever you hackers daydream, I need a report on the status of our satellites," Alex is standing beside him, with her arms crossed and a questioning stare, "If you aren't too busy, of course?"

"No! No, of course not." He starts typing frantically on his computer, running the testing program as Alex requested. Testing the satellites was something they did often when the day was rolling slow, but Winn had already done that the day before and Alex's request now feels more like an excuse for starting a conversation, because she has leaned against the desk and is now waiting with an absent look on her face.

"So," He says while the little green numbers of each satellite start appearing on the screen, "Everything ready for the Danvers' New Year's Extravaganza?"

"Kara has that covered. We're only short of a contingency plan in case something goes wrong."

"And we all know that that is highly probable," He jokes.

"I'm going to bring Maggie," Alex crosses her arms and turns slightly to look at him.

"Okay. I like Maggie," Winn states, but then he watches as Alex's stances becomes a bit unsure and nervous before she utters the next words.

"As my girlfriend."

The numbers on the screen suddenly stop. The test is finished and Winn's eyes are fixed on the little green OK at the end of the instructions.

Okay, it's not like he didn't know. More than once Maggie has strutted into the DEO headquarters, wearing her usual confidence and dimples, and greeted Alex with a kiss. The first time had been unexpected and completely unintentional on their part, more like something done out of habit, and Alex couldn't look in the eyes of anyone at the building for the rest of the day. Winn decided that the best thing he could do was give her time and space. So, of course, he did the next best thing and asked Kara about it. After babbling a little about how she shouldn't talk about that because it's Alex life, and how much she respected her sister's privacy, Kara finally told him how difficult the last few months had been for her Alex, how she was slowly learning to navigate this new aspect of her life, and that the only thing she really needed at that moment was for them to act like nothing had changed.

Beyond Alex smiling more than usual, nothing has truly changed, so Kara's request wasn't hard to fulfil.

"Is that… okay?" Her voice trembles a little and makes Winn realize that he's been on his own world thinking for too long. He's never heard Alex sound so vulnerable before, and Winn knows without a doubt that this is important for her. Somehow, this is Alex's way of telling him that, even if she doesn't need him to validate her choices, she values him enough to care about his opinion.

Winn turns on his chair and smiles at her.

"As I said, I like Maggie," He shrugs, trying to lighten the conversation, but then his face turns a bit darker, because this is the part where he finally gets to be a brother, "But if she breaks your heart, I won't stop Kara from throwing her into deep space."

Alex looks shocked for a hot second, and the way time seems to stop makes him wonder if he's crossed a line. But then she starts laughing, and Winn swears that he can see how the heavy weight that she carried on her shoulders dissipates.

"Hey, don't laugh! Your sister might look like a puppy, but she would totally do it." He says trying to muffle his laugh, "Kara is fucking terrifying when she wants to be."

"Well, she kind of scared Maggie the first time they met," Alex points out.

"Oooh, Kara was definitely angry that day. She looked like she wanted to melt Maggie with her heat vision."

All laugh coming from Alex suddenly stops, and the happy grin that she was wearing until now is slowly replaced by a shocked, wide eyed expression on her face.

"Oh, shit."

"What? What's wrong?" He asks. Alex brings a hand to her hair, nervously, like she's just realized something.

"Maggie doesn't know about Kara."

New Year's party is definitely going to be eventful.
