Sister

Sister is an slaver found in Rivet City in Fallout 3..

Background
Why do they call this large hulking man "Sister"? No one knows because whenever anyone asks, Sister beats them to within an inch of their life. Sister, 29, is a bully with a bad temper. He is one step away from being given the boot by Harkness or Danvers. So far he hasn't caused enough trouble to warrant exile or worse. Most of the citizens of Rivet City stay clear of him if they can.

He is actually a slaver, operating at Eulogy Jones' request in Rivet City to capture an escaped android. However, Sister has grown to like living in Rivet City, for which he has abandoned this mission indefinitely.

Other interactions

 * 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.
 * It is possible to anger Sister so intensely that he refuses to talk to the Lone Wanderer ever again, making it impossible to complete the "Slave Hunt" quest in his favor.
 * Killing Sister, lockpicking his door and taking the belongings in his room do not result in a loss of karma. However, the other residents of the ship will become hostile to you.
 * If you pickpocket a grenade into Sister's pocket while undetected, the residents won't become hostile.

Quests

 * The Replicated Man: In his room is a recording pertaining to the quest, concerning the Slavers' desire to enslave some androids.
 * Slave Hunt: When the Lone Wanderer first meets Mei Wong, she seems very afraid of Sister. The Lone Wanderer can help either Mei Wong or the slaver and receive good or bad karma based on your actions.

Appearances
Sister appears only in Fallout 3.

Bugs

 * If you don't agree to help Mei Wong but kill Sister yourself, there is a chance you won't have any change 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 just now".
