Gob

Gob is a ghoul bartender at Moriarty's Saloon in Megaton. Treating Gob kindly will open up generous discounts and reveal some more of his personal past. Talk to Gob and other occupants of bar and you will learn that Gob was sold by Slavers to Moriarty and occasion has mentioned his mother and hometown. Through dialogue with Nova, the local prostitute, it is said that he's been stuck working for Moriarty for 15 solid years until he pays off his debts (which he's struggling to, as he needs to pay rent and food as well). Some bar patrons say that Moriarty treats him bad and would even suggest at him being the town's punching bag. Despite his appearance and the towns disrespect, he is depicted to be a fairly nice guy.

When you talk to him he will mention that next time you go to The Underworld say "hi" to Carol. Though he doesn't tell you this she turns out to be his mother.
