My plan for fallout is to kill Arc (preplanned) I just needed a good scenario that shows his heroism. I'll need your help though, after he dies Spark will become enraged and start killing everything (she'll be pretty much superpowered) . You can't kill her, simply take the vial around her neck and force her to drink it. (Write about fighting her, I'll write about her insanity and have her remember something and she'll pretty much give up, but that is what I'm writing.)
