T.J. is grim, middle-aged, and not very talkative. He doesn't like Porter much, probably because he wants to be in charge instead. However, he knows no one would follow him, and he wants to leave Denver because he doesn't think there is anything to gain. T.J. likes to hang out with Hardin.
T.J. Reilley has not appeared nor is he mentioned in any published game. He was to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if he will appear in any future Fallout game.
