Chapter Text
There were a lot of human concepts that Kara didn't understand. Relying on the Danvers to explain them to her. Most of it was foreign but somewhat normal, until one day they spoke about soulmates in high school and she found out just how different Earth was.
The concept sounded slightly crazy and she thought it was a joke at first until she noticed that everyone in class seemed serious about it. So she took notes on it, getting ready to ask even more questions to Eliza once she got home. She didn't want to ask them in front of everyone else. Afraid they would find it weird that she didn't really know about it.
In class, her teacher had explained one day, after they turned eighteen, all of them would find themselves in a loop. Reliving the same day over and over all because they walked past their soulmate at any point during that day. Maybe even exchanging a few words. It sounded unrealistic and Kara would have argued such thing was impossible but she did have superpowers which should be impossible as well. So she sat quietly, taking in all the information.
Apparently, the only way to escape it is to introduce yourself to the other person. Which sounds relatively easy but it's not. Her teacher explained it's easy to go crazy when you're reliving the same thing over and over again while trying to find one person in the middle of what could be thousands that you walk pass at any given moment. Many people gave up and the teacher didn't have to tell them how they did that, it was implied that death was the way to escape that loop.
Kara didn't see what the issue was. It sounded like an adventure to her.
Her teacher continued on to tell them that everyone else wouldn't be aware of what was going on, for the, it would be another ordinary day and they would have no memories of the previous ones where both people failed to introduce themselves so time kept on moving and that if they do mention what is happening to anyone, or even hint at it, even their soulmate, then there would be terrible consequences. Again, she did not tell them what these consequences were but judging by her face, it would be bad.
That night when she got home and started asking questions, Eliza sat her down and explained what it had been like for her and Jeremiah. Telling her they hadn't told her about it because she was too young to worry about such thing and that they weren't certain such thing would happen to her considering she was not from Earth and such concept wasn't the norm in Krypton.
From then on Kara didn't think much about the entire thing, not really expecting it to happen to her. Of course, she wouldn't have a soulmate. She wasn't even supposed to be on this planet.
The only times the whole concept even crossed her mind, reminding her such thing existed, was when someone mentioned it had happened to them.
Like the time when James told the Superfriends about Lucy and him. Causing Kara to be slightly jealous. Not because she liked either one of them. Although she did have a crush on James at some point. But she knew he would have an Earth soulmate so she never acted on it. She was jealous because she was now in her twenties and it hadn't happened to her. Of course, there were several people who hadn't gone through it either. Like Alex. But in her mind, it only confirmed that she didn't have a soulmate.
One day Alex came to her apartment, clearly freaking out but not really speaking about it and Kara knew. She knew what had happened. She didn't need hints at all. She only had to look at Alex and how freaked out she seemed.
"Alex, do you know how to stop it?" She didn't want to say anything about a someone. Not wanting to know what the consequences would be for her sister if she did.
She nodded, "I think so."
"Then why are you here?"
Alex was pacing around, her hands shaking. "It's not what I expected, Kara."
"Okay." She spoke, placing a hand on her sister's trembling one. "Do what you have to do, Alex. Then we can talk about it, okay?"
Her sister nodded, hugging her and rushing out of the door.
The next day she knew that Alex had gone through with it as she remembered that happening and it was clearly a different day.
They hung out for a while in her apartment later at night and Alex told her about what had happened to her. Apparently, it all started at the crime scene she had gone to.
The first time she had spotted a detective but had sent someone else to deal with her. The second one she was already annoyed by having to relive the same day and slightly excited so she didn't feel like dealing with cops. Which caused her to speak to the detective herself. This cop had looked at her curiously as if this action had surprised her and Alex walked away, leaving the woman standing there in shock, apparently. Not even realizing that she had been surprised because Alex hadn't done the same thing as last time, which meant it was her. Considering Maggie had constructed a plan to act exactly like she had the time before. Which meant whoever acted differently was her soulmate.
Alex rolled her eyes, complaining about how smug Maggie had been afterward, about her plan working.
She also told Kara how it had taken her a few hours to notice how that woman had acted and consider the possibility. Which caused her to question everything she knew about herself. Including her own sexuality.
Her sister mentioned how scared she was and that's what made her go to her apartment. Looking for someone that would tell her that she should just go for it.
Alex knew that later that day she would see the woman on the crime scene and that time she finally introduced herself. Which caused the detective to smile and Kara chuckled when her sister told her that she nearly melted right there and then. But it wasn't until she woke up the next day that she knew for sure. And somehow, there she was, later on at yet another crime scene.
Once they could speak about it, they had talked for hours and exchanged numbers. Setting up a date right away.
Kara was happy for her sister who had waited for so long to meet her soulmate. And she was especially happy about her finally figuring out why she was never that into guys. Although Alex had always argued it was only because they weren't her soulmate.
But she was also envious. Wishing she too could have a soulmate despite the fact she wasn't human.

Kara woke up with a phone call. It was her day off from CatCo and she had planned to spend a relaxing day inside. All she wanted to do was order take out and watch movies. Nothing else. Certainly not work. Of course, realistically she knew the days in which Supergirl wasn't needed were rare at best.
She sighed, picking up the phone.
"What is it?"
"Hello to you too."
"Alex, it's too early."
"You barely need sleep and we both know it."
"Yes, but I do enjoy a comfortable bed and nice dreams."
"That's too bad. We have a job to do."
She grunted, finally sitting up.
"What's up?"
"Lena Luthor is holding a rebranding ceremony and we think she might be targeted. Apparently, there was an attack on her life yesterday but luckily nobody was harmed."
"Rao, the Luthors will be the death of me."
Alex was silent on the other side.
"Oh, come on. That was an excellent joke."
"Kara, no."
"Fine. I'll be at the DEO in five."
