A guy who's really good with knives. He fell while climbing, broke his leg, and had to drag himself back to town. He's done something to offend the shaman Merrin, and she won't help him. He's worried that this will leave him crippled and he won't be able to be a warrior/raider any more; he's not ready to become useless.
Fast-Hands 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.
