A particularly rough and nasty person, Dermot puts on the persona of a hardworking and honorable prospector that likes to just relax on his off days. But the reality of the situation is that Dermot and his partner in crime, Saint James, are slavers who have been kidnapping and enslaving refugees around the Aerotech Office Park area for little over a year and selling them to the Fiends for a profit. Dermot has a particular mind for keeping his business profits straight and always updates a ledger on the businesses he's done before with prospecting and now (unwisely) for slaving. Along with documenting profits, Dermot also writes notes to himself about how to improve his craft, how to keep Saint James from getting to the children, and any other situations of note.
↑The Courier: "I hear you and your partner are coyotes." Dermot: "Don't believe everything you hear. Me and Saint James earn our caps working salvage. It's hard work, so when I'm not working I like to relax. Which means it's time for you to fuck off." (Dermot's dialogue)
