Kara

Every single minute since she landed on this planet is imprinted on Kara's memory, from the moment Kal-El ripped out the door of her pod, until this very second, while she's watching the showdown between Alex and Winn from the comfort of her couch.

They've reached a tie at Pictionary and both teams are playing at the same time to decide the winner. Lucy couldn't make it to Game Night, so they had split into boys vs. girls teams, with one of the girls sitting out one round each time. Now it's Kara's turn to watch from outside and control the time, but she has been a bit distracted all night, and the final battle wasn't going to be an exception.

The whole time her attention has been focused on one thing only; her sister's smile.

Since Alex and Maggie stepped into her apartment tonight, Kara has been searching through her memories, trying to remember if she'd ever seen such expression of pure happiness in Alex's face before. She'd seen her smile, of course, she'd seen her happy, but Kara can't recall her sister beaming like that, not a single time since the day they met.

Kara has a lot of memories of her life with Alex, but there are three moments that she will never forget. Those three memories are what shaped their relationship and what made Kara who she is today. More than Krypton, more than the stars she left behind, more than Jeremiah, Eliza, Clark or any other person in her life, the fact that the Universe put Alex Danvers in her path is what made Kara the hero she is.

The most important memory that she has is the very first moment she saw Alex. Kal-El had explained to her that she was going to live with a family that would take care of her, that would give her the life that he couldn't, and she never questioned it. But she was terrified of this new world, where the sun was yellow and little winged creatures flew over her head, and neither Kal-El's hand holding hers, nor the Danvers' candid smiles, made her feel at ease. It wasn't until Kara raised her eyes from the ground and caught a glimpse of a young girl at one of the windows of the house, that she stopped trembling. Kara saw curious eyes staring back at her and, for the first time since she left her pod, she felt grounded.

"That's our daughter Alex," Jeremiah had seen her staring at the window and smiled, "I'm sure you two will love each other in no time."

Now, every time that Kara feels like she doesn't belong, like she lost herself the same day that Krypton died, she looks back to that moment and remembers Alex's eyes staring at her with wonder. It reminds Kara that a home isn't a planet, a city, or a house. Home is the feeling of Alex's arms around her, the silly songs that she used to sing to her the days that Kara couldn't stop crying, the nights under the stars, and the certainty in her sister's voice when she tells her that they will always be together.

The second memory is the sound of cracking bones when Alex punched Bobby Decker in the middle of the High school's hallway. She has it engraved in her mind as clear as the day she heard it. It wasn't that Alex had never gone to her rescue before, but it was the first time that her sister got hurt protecting her. Kara doesn't even remember what happened, just Alex storming into the scene, taking the boy by the collar of his shirt, and punching him square in the face with such rage that he ended up bleeding on the hallway's floor. Seconds passed in silence while no one knew what to do. Kara could only stare at her sister in awe, until she saw a few rebel tears gathering in Alex's eyes while she stood stoically over the winy boy on the floor. Kara knew then that Bobby Decker's nose wasn't the only thing broken that day.

Alex spent her two weeks of suspension at home with a cast on her hand, and a very angry Eliza reminding her that things like that would have consequences, but when she returned to school nobody dared to say a word about Kara or be mean to her for a while. Her sister always told her that it had been worth it and that she wouldn't hesitate to do it again, but from that moment, Kara tried harder to blend in. If she saw something that she didn't know, Kara would take a mental note to ask Eliza or Jeremiah later, instead of asking people on the street. If she didn't understand something in class because it was completely opposite to what she was taught on Krypton, she wouldn't raise her hand to ask the teacher, and would wait until she arrived home to ask Alex why it was different. In time, Kara learnt to mimic the other kid's behaviour, just adding a bit of herself; she was extra nice, always helpful, and never lost her smile.

What Kara never realized was that, while she was getting closer to people outside of the Danvers's household, Alex was drifting apart from everyone but her.

It wasn't until years later, when Alex revealed that she worked for the DEO, that Kara started wondering how much her sister had to give up to keep her safe. She'd had even preferred to die instead of letting Kara reveal herself to the world.

The sight of Alex's plane going down in flames is that third moment engraved in her mind forever. It's what her nightmares are made of.

It makes Kara furious to look back at all those times when Alex has put her first, when her sister's happiness, her safety, Alex's own life, had been put on the background because the alien child that dropped at her door had to be protected from the cruelty of the world.

That's why she's grateful for Maggie Sawyer coming into their lives.

It is true that since Supergirl joined the DEO, her sister had started to be more open, a bit friendlier, warmer, and that even her relationship with her mother had improved, but she was still too focused on her job and her personal mission to protect Kara to worry about having a personal life.

Luckily, all it took was a stubborn detective storming into her crime scene to make any sense of control that Alex could have go out the window.

It's not that Kara has completely forgiven Maggie, because getting out of her mind the memory of Alex crying in her arms for hours won't be easy, but she won't be able to stay mad at the detective for much longer when she's making her sister smile like it's Christmas every day.

"Yes! I win!" A victorious Alex raises her arms and grins at the others, taking Kara back to the present.

"You cheated!"

"I do not cheat, Schott. Ever."

"How do you even cheat at Pictionary?" Asks a bemused Lena.

"She and Maggie probably have a secret girlfriend language or something," Winn turns to Maggie and points at her, "Do not think that I haven't seen you making weird signals at Alex."

Maggie smirks and leans back on the couch, making enough room for Alex to snuggle into her side.

"That had little to do with the game," She clarified, "I just find my girlfriend's competitive strike extremely enticing and I was letting her know as much."

And that is Kara's cue to jump into the conversation. One thing is being glad that Alex is happy and in a healthy, strong relationship, and another completely different wanting to know the exact reason why her sister hasn't stopped grinning all night.

"Ookaaay! Who's in for some Monopoly?"
