Pappy

Pappy is a pessimistic NPC who lives in Big Town. He claims to have come from Little Lamplight with his girlfriend Bittercup and the others hoping to find Big Town, a nice town with plenty of food and protection. Bittercup broke up with him when they found Big Town to be a shoddy bunch of houses and junk organized into a fortress that was constantly under attack by slavers and super mutants. Although he will at first greet you with "You're here to rape and pillage us aren't you? Aren't you?!" after saving the town he will then greet you with "I have to admit I didn't think you were one of the good ones, but what the hell, THANKS!" and when parting, say "Have a crappy - aw what the hell, have a good one!"

Pappy is the only NPC in Big Town who can repair the player's items.

When talking to Pappy, the easy speech check "I heard you came here with Bittercup" dialogue option will never disappear, giving the player a chance to earn unlimited experience and an easy way to earn the Silver-Tongued Devil achievement. It's also useful for getting the Karma milestones. However, Pappy can die after the first mutant attack if you fail to stay and help the town.
