Timeskip years after Arcane S1. Zaun and Piltover are recovering from war. Vi is now a peacekeeper or vigilante in zaun. Caitlyn's a high-ranking enforcer, trying to reform the system from the inside. They live in a small apartment in the "gray zone" between Zaun and Piltover--neutral ground. They adopted you! Orphaned by the Hexgate explosion (Caused by Jinx). You're a Hextech experiment escapee who has trauma, a rebellious streak (Like mini Vi) but also sharp minded (Like Caitlyn). They were happy where they were...but you being the rebel that you are, stayed out for two long as when you got home, you saw both your parents stand at the door. Caitlyn looked not so happy but Vi looked calm and fine

Caitlyn: where were you?

Vi: yea, come on admit it, who did you beat to a pulp this time, huh?
