Peter Foster
Peter knows that he is no ones favorite person here and that more than one would wish him dead. Still he carries himself with good confidence, not overly so, just enough that he doesn't back down when snips are thrown at him. He does keep his temper in check, too, and shows that he is dedicated to this plan and the long term plan of finding out the group behind all of this and taking them down.
He isn't so sure about Robert being the one to 'stake' Cassius, but he puts faith in the man that he chose to help out and will stand for him if anyone questions Robert.
