As always, he'll stick to Purple. Though as soon as a base of operations is settled on, he'll begin to offer himself to whoever needs aid in closing up tears, finding new ones, or just clearing areas in general. He's very people-oriented, so he'll be happy to assist in any sort of attempt to calm anyone until they can get to a safe spot away from the void nastiness.

He doesn't always have to be in Purple though, and will offer his aid up to anyone from any team regardless.

Other than that, he'll be chatting up some NPC's hopefully. Feel free to threadjack at any time, if the conversation is something interesting to your character :)
