The more I think of it, maybe it'd make better sense to switch Cleric and Chamber. Katie would probably be more of a liability than a help in a massive battle like that, since she'd have no powers to rely on for self-defense if it came down to it, so maybe she'd be better off at the school. Jono, meanwhile, I'm thinking by that point will have acquired at least enough control over his powers that he'd be willing to go out and help blow stuff up, which he's very good at, so he should probably go along with one of the Sentinel hunting groups. Thoughts?
Sam, on the other hand, is just excited that he gets to whoop some metallic butt that isn't Colossus (Super Smash Brothers ftw!).
