"No....but no option seems good at the moment." Vincent says, frowning a bit. "There's no point in lying really." He says imply. "I have nothing to gain from doing it." So he doesn't see the point in doing it. "You'd stay back? Say nothing and do nothing? They wouldn't know you were there?" He doesn't trust Alexander, but he knows they wouldn't trust any letter or anything just there and all, would they?

(And then, they attack Vincent, assuming he had betrayed them XD)
