Wounded and a little deaf right now, he seems pretty angry about something. He and Garcia found The Box, incurring injuries (minor concussion, some hearing loss) from Bombay Jack's explosives when they tried to crack it open.He wanted to go back and kill BJ, and get his claim back. A real jerk-ass asshole. No matter how bad things get, he refuses to leave his claim, looking out for it and ignoring what happens to the others.
Davis 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.
