I think that if Cas bites it, Heaven will have no more interest in the boys? There's no more vessel nonsense they have to deal with.
It's been stated that Raphael wants to restart Armageddon. For that, she needs vessels for both Michael and Lucifer to occupy once they're freed. Of course, before that her motivation seemed to be a nihilistic certainty that God was dead, and before that she was obeying orders and watching over Chuck. Who knows what her intentions will be next season?
If the vessel issue were to arise again, then that just ensures that Dean and Sam live (even if it involves them being brutally murdered and reanimated repeatedly).
Unrelated to everything that preceded it, can someone write a letter to Sera and ask her for
one
more bitch/jerk exchange before the series ends? I would send her flowers.
Also unrelated, but I'm sad there won't be cowboy hats tonight.
dying here with the fanservice!
Whoa! Now we've lost another one.

Whoa, they've completely, one hundred percent given up on any kind of subtlety, haven't they? The next angel actually will be named PhanServus.
