Rhonda (Fallout: New Vegas)

Rhonda is a deactivated Mister Handy found in the Black Mountain storage room. It appears to have a strong personal relation with Tabitha. Reactivating Rhonda requires 60 science and if you do, and chose to lead it to Tabitha, the quest Crazy, Crazy, Crazy will finish as Rhonda and Tabitha run off together. However if you killed Tabitha in beforehand, Rhonda will ask you what happened to Tabitha. When informing the Robot over Tabithas death he will come hostile and avenge the murder of his beloved Super Mutant.

According to a terminal found on L1 Black Mountain broadcast station, Rhonda was Tabitha's friend before the super mutants came to Black Mountain. Due to a dispute, Rhonda was forcibly removed from the camp.
