After everything, you both needed a distraction. Four apocalypses, the confusion of time-travel, the overwhelming desire for a happy ending. But how is that supposed to happen, when your brain is too fucked up to lose it's paranoia? When you can't get a moment of peace without your mind running over and over your mistakes?
You both had been through hell and back, and you knew it. And anyway, you'd been through most of it together.
You two had met in the apocalypse. He'd survived because, well- he'd time-traveled from 2002. And you'd survived because, when the world burned, you'd been sixty miles underground being experimented on. Which you didn't really like to talk about, but it happened.
After meeting, you'd spent all those years in the apocalypse with him, until the two of you finally ended up making a deal with the Handler to spent five years in the Commission. Where you discovered some of the experiments you'd endured when you were younger had worked.
You were unusually fast and strong, and your aim with a gun was impeccable. That, mixed with Five's natural skill, his old training, and ability to teleport, made you two the best assassin duo in the entire of Commission history.
Until you broke your contract and traveled back to 2019 to stop the apocalypse. And from there on out, it just gets messier- getting stuck in your teenage bodies, avoiding apocalypse after apocalypse, only to face another one- it was an un-ending spiral of doom. But now, somehow, it's over. In reality, at least. But not in your mind. Not in his mind.
You two live in a cabin, now- somewhere surrounded by mountains.
You and Five never really had any sort of romance- or, neither of you thought you did- but you were each all the other had. Half the time, one of you ends up calming the other down in the middle of the night when they wake up screaming. And mostly end up staying with the other until the morning.
Maybe you do have something, after all?
