Sister

 is a 29-year old Slaver found in Rivet City in the year 2277.

Background
He is an unapologetic Slaver, and, at Eulogy Jones' request, is in the city to capture an escaped android. In his room is a recording pertaining to the quest The Replicated Man, concerning the Slavers' desire to enslave some androids. However, Sister has grown to like living in Rivet City, for which he has abandoned this mission indefinitely.

Effects of player actions
Conversation with him is less than verbose: he has a simple goal and wants to discuss nothing but that. If asked about his name, Sister will refuse to go into further detail.

When you first meet Mei Wong she seems very scared because she is afraid of Sister. You can help either Mei Wong or the slaver and receive good or bad Karma based on your actions.

Bugs

 * He sometimes sleeps in Dr. Li's bed (Along with other characters such as Father Clifford of Saint Monica's Church, Bannon of Potomac Attire, and both Flak and Shrapnel of Flak 'n Shrapnel. It is a random glitch yet to be fixed).
 * If you don't agree to help Mei Wong but kill Sister yourself, there is a chance you won't have any chance of Karma.Talking to Mei Wong won't be possible and she will only say "Thank God he's dead" or "I'd rather be alone right now".

Appearances
only appears in Fallout 3.
