Vera Wylde and Jessie Gender take up residence on Babylon 5, taking in one episode at a time.

Season 3, Episode 4, Passing Through Gethsemane - A member of Brother Theo's order, Brother Edward, starts having strange visions while on board Babylon 5, which may tie into some nasty events from the past. Yeah... that's kind of it, this one doesn't really have a B-plot. Unless you count Jessie trying and failing to correctly pronounce Gethsemane.
