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.
At Eulogy Jones' request, he is 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. Despite now being a permanent resident in Rivet City he rents a hotel room and can often be found sat in the hotel lobby.
