I'd like to attempt at throwing a wrench in the "Olmos a Dark Passenger Theory." If it were the case that Olmos was a Dark Passenger, in the scene where he burns himself, it would actually be Travis taking the poker to his own wrist (if it wasn't, then that scene was totally useless). It'd be pretty cheesy of the writers to omit the burn/scar on his wrist for the rest of the season until we find out Olmos was indeed a DP.
