Davin

Davin is a joinable NPC in Fallout 2.

Davin is the son of Grisham, the slaughterhouse operator in Modoc. Either male or female characters can add him into the party by sleeping with him and then marrying him (in a shotgun ceremony). Once married, Davin will not leave the party unless killed or divorced. His character has low skills, and (unlike regular joinable NPCs) does not improve.

Davin's sister is Miria, who can also be married instead.
