So,
the latest rumor is that Misha Collins might not just have a reduced role next season. He might be exiting entirely, once the cliffhanger is resolved.
If this is true, if this whole heaven civil war story line has merely been an elaborate plan to get rid of Castiel entirely, I hereby take back every nasty thing I've thought or expressed about the writers... since midseason.
All of the other angels are dead. Uriel, Anna, Gabriel, Raphael, Balthazar... Lucifer and Michael are as good as dead. All of the angels we've met, aside from Castiel. If Cas goes, so go all of the angels.
Hallelujah.
Here's to hoping.
