Anson heads the brothel, and really, reallyIn-game spelling, punctuation and/or grammar despises women, but doesn't overtly show his hatred. He's usually very calm and emotionless, as is typical in this well-ordered town, and runs a tight ship with his combo tavern/brothel.
Anson 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.
