When it's with an NPC or a monster I wouldn't worry too much about that thread, but when it's between two or more PCs then that's when it tends to get cluttered and slow everyone else down.  I can understand your point Melisa but I just feel better having it lol.  Anyway, as I said, NPCs and monster attacks/rapes aren't needed to change into the other thread, but PC scenes are however, and that way you don't have to feel rushed in such things.  ;D
