Davin

Davin is a joinable NPC in Fallout 2.

Davin is the son of Grisham, the slaughterhouse operator in Modoc. He can be added into your party by marrying him. He is a useless tit, so don't bother wasting an NPC slot on him. Unless you're that much of a badass, of course.

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