Concerning an NPC killing another...When does the nun kill the whore? I don't want that to happen, but I saved the whore, accepted her blood, and consumed the item before saving the nun. I heard that is the trigger, but after saving the nun, zoning a few times, and accepting/consuming the nun's blood nothing has happened. Does that event happen after killing Rom or am all in the clear? I don't want to miss furthering the whore's quest line and wonder if I should kill the nun or if it is safe to progress.
You will have to kill him now, otherwise consider her a dead body.
