No supplies, as of right now. So no need to throw that into your CS. And as for the going against each other, that is up to your character to decide whether or no he and/or she will help the others. At first we'll all appear together, so again, we're going to have to see what happens IC.

EDIT: It might sound or be worded odd in my writing, but what I'm trying to hint at is that it will be more thoroughly explained IC what is going on.
