Pyrrhic Victory Lucifer is gone, but Castiel is trapped inside the Fade, and no one knows if Lucifer is actually in the Cage that Gabriel built. Gabriel, Dean, and Sam are injured, and something's wrong with Asala's Mark that keeps her from just opening up the rift again. Probably some arguing about getting Asala to work at opening the rift just one more time so that Dean and Sam can try to get Cas and save him.
(Open to all, since people standing guard aren't in danger of being exploded.)
