Winthrop

Winthrop is the maintenance man/chief engineer of Underworld. He maintains all things electrical or mechanical in the city, as well as the Mister Gutsy class sentinel robot named Cerberus. His name might be a reference to an innkeeper in Baldur's Gate. According to the Fallout 3 Official Game Guide, Greta is his "girlfriend", but this is contradicted in-game, where Greta is Carol's "partner".

Repeatable quest: This Old House
Due to a steadily declining supply of resources Winthrop requires Scrap Metal in groups of 5, in exchange for medical supplies (Stimpaks, RadAways or Rad-Xs.)

Appearances
only appears in Fallout 3.
