It had all started back when the DEO was made aware of an illegal alien fight club. Kara had showed up to the warehouse to confront Roulette when she locked eyes with the brunette. Here was a woman who had captured aliens for the entertainment of the rich and affluent, and yet, on some level Kara couldn't help but want what the captured aliens had. While making them fight to the death was awful, they at least had a place where they could take out their aggression without causing massive damage to the city. If Kara so much as twitched the wrong way, she could destroy something that was probably expensive. The old broken down cars that she had stored at her warehouse weren't very useful to her to use for anger management and Kara could admit she was a little envious of the aliens here. After all, it wasn't like people at the DEO were lining up to spar with her. She needed someone that could and would fight back. Someone that could take one of her punches and live if she didn't hold back.
But she had a job to do and the DEO to answer to, so she fought and won that day. Roulette got away and Kara thought it was over, though Roulette's words from earlier played on repeat in her head, "Thing you'll learn about me, I only play safe bets. And you, little girl, are as safe as they come." She thought little of it, until Slaver's Moon happened. She again met Roulette and again was taken back by how ambitious the woman was. Her eyes glinted as she told her captives just how profitable the intergalactic slave trade was. Mon-El had hovered over Kara's shoulder, making a pitiful attempt to back Kara up, and honestly by that point, she just wanted to deliver a strong elbow to his face to get him out of her space. Alex had saved the day and her sister once more, saying she would always be there for Kara.
And then Jeremiah came back. While at first, Kara had been ecstatic to have her adoptive father back, Mon-El and Winn had convinced her just how coincidental his return really was. She had expressed her shock that Winn was talking to her again and he quickly let her know that he was only talking to her out of a favor for Mon-El. So he was still mad, and she could deal with that. She could deal with Winn and James not talking to her. They just needed a little time and space. She hated time and space. She was just trying to protect them. After all, they were only human and could be killed easily. But when she tried to tell Alex about Jeremiah, all she got was a sharp rebuke. Alex didn't want to believe that it was weird for her dad to come back like he did. But she was Kara Danvers and she didn't give up easily. So she went to Alex's lab to try and talk to her again. But Alex didn't want to calmly discuss the situation, she didn't want to see that Jeremiah's timing was weird. Things had quickly gone from bad to worse, with Alex stating that Kara had obviously chosen her side. Alex given Kara an ultimatum: she was either part of the family or she wasn't. Kara deflated, Alex didn't mean that, she couldn't. Her sister wouldn't make her choose. Alex cut her off, putting emphasis on the fact that Jeremiah was her father, with a not so subtle implication that he was not Kara's. And when Kara had tried insisting that he was her's also, Alex's face morphed into something mean and vicious, spitting out, "No, he isn't! Your father is dead!" Kara's face crumpled, her knees giving out slightly from under her. Alex had a shocked expression on her face. She couldn't believe she had really just said that. She reached out for Kara, but the blonde just shook her head, tears gathering quickly in her eyes. She stumbled away from the brunette, using her superspeed to get away before anything more could be said.
Alex decided to give Kara a few days to herself before she went over to her apartment to apologize for her harsh words. But then Cadmus had struck. Jeremiah turned out to be a spy for the shadowy organization. Luckily, they had caught him right as he was downloading the alien registry from the DEO mainframe, and foiled Cadmus's plans once again. Jeremiah had let them know that those plans had revolved around sending all aliens off planet, starting with National City and then expanding across the planet until finally all of the world was alien-free. The man who she had looked up to for so long was deluded. He had gone to work for the DEO to protect Kara, and yet he had seemed to forget all about her being an alien because he was "doing all of this for Alex." So, when the dust had settled and Jeremiah had been locked up, Alex went over to Kara's apartment. She got no response at the door, which was understandable since Kara was probably still mad at her, so she opened the door herself with her spare key. But the apartment was empty. Sure all of the furniture was there, but it looked as if no one had lived there for days at least. The couch was devoid of any and all blankets that had once rested there for Kara and Alex to snuggle under during their Sister Nights. A good amount of Kara's clothes were gone as well, leaving behind the many cardigans she had always worn to work at CatCo. She was about to call Winn to see if maybe she was using her Supergirl suit and he could track her when she saw it draped on a hanger at the back of Kara's closet. Maybe Kara was just out somewhere in the city? She grabbed a beer from the fridge when a note on the table caught her eye. She walked over to it, thinking it might be Kara letting her know where she was in the city, but as she read the document, tears formed at her eyes.
Alex-
I've never been great at writing letters, since I've never had anyone to write to, but this is for you. I've decided to leave National City and I'm not coming back. No one needs me here, either as Supergirl or Kara Zor-El. The DEO can handle any threats without me. Winn and James don't need or want me. They haven't talked to me in weeks, the one exception being when Winn told me about Jeremiah, and even then, he did it as a favor to Mon-El. I'm not speaking with him either, though that was my choice. He was getting a little too pushy when it came to a relationship, wasn't leaving me alone when I asked for space. I could barely ever get a minute to myself, so I told him not to come around anymore and not to talk to me or he would receive a fist to his face. Thankfully, he backed off.
I guess now would be the time to tell you that I was fired from CatCo. Snapper kept giving me assignments that were mostly fluff pieces, except when he needed a quote from Lena. Anyways, I decided to let people know what was really going on when no one else was. So I became a citizen journalist and told the public about Cadmus, asked them to be safe. Apparently that was a violation of my contract with CatCo, so Snapper fired me. So I lost the one thing that made me feel normal, like a regular person. You know how important that job was to me, Alex. Or at least...you used to. Do you know how long it's been since we had a Sister Night? Me neither. Over the past few months, we've drifted apart.
Once, you would've come to me if you needed to vent or just wanted to talk, and I would've gone to you. But you have a whole new part to your life now. You have a wonderful girlfriend, and I understand if you want to spend time with her. But...the distance between myself and everyone else has only increased and I just can't stand on the side and watch everyone's lives move forward but my own...not anymore. You were right, you know? I'm not a Danvers. I never have been and I never will be a Danvers. My family is dead, my planet is dead, and everyone I once knew is dead. I am one of the last of my kind and I need to put more focus on that. So from this day on, Kara Danvers is dead and Kara Zor-El? Well, all I can say is that Kara Zor-El is a free agent.
Sincerely,
Kara Zor-El
Heir to the Noble House of El
