Technically, Xur dies and is recreated all the time. No action required. Amanda at least has a decent back story, but Vuvuzala? -blam!- that guy right in the mouth. Anyone willing to stand by the still-warn corpse of a close friend and refuse to get upset over it, because they are paralyzed by fear of taking a chance....the carbon that became your mothers ovaries is wasted on you. Maybe we get lucky, and we'll get to pull an Uldren on Zavala.
