That's actually a really cool idea. I've done it in another roleplay where the characters had already met and the story started a week after their meeting. I can look it up to see how we did it.

But how would that work for our gang? Since we haven't actually met yet. Like what they would think after they first met?
That depends on how they meet I think. I mean if Sarah for example helped Malena escape with her enhanced strength, Malena would have a different impression of her than say maybe Tori being stand offish.
