Biff

Biff is the brother of the slaughterhouse owner Grisham in Modoc and the uncle of Miria and Davin, in 2241.

Background
Biff is presumably a farmer in Modoc, since the whole town's economy relies on farming. He does not appear unless his brother Grisham dies (see Interactions), at which point he moves in and takes over his brother's slaughterhouse and also becomes the guardian of his niece and nephew. He is very conservative, like Grisham, and will insist on honoring his brother's wishes by marrying off his children should he catch them in bed with a stranger.

Interactions with the player character
If Grisham has been killed and The Chosen One sleeps with either of his children, Miria or Davin, Uncle Biff appears to deliver the same shotgun wedding ultimatum offered by Grisham when he is alive.

Appearances
Biff appears in Fallout 2.
