Sister

is a man found in Rivet City. He is an unapologetic Slaver, and is in the city to re-capture an escaped slave, Mei Wong. Conversation with him is less than verbose: he has a simple goal and wants to discuss nothing but that.

The player has two options (other than ignoring the situation entirely): Aid Sister in recapturing the slave or providing Mei Wong with caps, allowing her to purchase a pistol to defend herself. Obviously, the first provides Bad Karma while the second is worth Good Karma.

A few days after making your decision, Sister will disappear from Rivet City, ostensibly either to return the slave to Paradise Falls or because he has fled or was killed.

If asked about his name, Sister will refuse to go into further detail. In his room you can find a recording with a female voice, indicating that Sister is an android.
