gwaevalarin | Because things can always get worse

It's hiatus, the season is nearing its end, and Paley has showered us with spoilers. Now I want to know, whether you are aware of any spoilers or not, what you expect from the finale. Best case scenario? Worst case scenario?

Here is my, somewhat cracktastic, speculation on where it is all headed.

I'm mainly working with two thing here:
1. The feeling that Crowley is not gone for good, that his own death was part of Crowley's plan to find Purgatory, that he is too clever to let Castiel find his bones, and that it was just too stupid a move, storytelling-wise, to throw away a great storyline like that.
2. "Certain regrettable things are now required of me."

Now with a few spoilers in mind, that I won't mention, because it's not important what they are exactly, and I want everyone to be able to join the discussion, this is my theory:

Castiel and Crowley have a deal - yes, you may discuss if that means that they kissed. Not what I'm going for right now, though. ;) - Crowley did something for Cas to help him with his war against Raphael, and in return Cas helped Crowley find Purgatory, and possibly brought Samuel back. Part of the deal was to "kill" Crowley and send him to Purgatory, probably with a return guarantee.
With Mommy Dearest not home right now, because she's roaming the earth, Crowley can easily take over Purgatory. And then he'll be back, King of Hell and Purgatory. And he'll be a good demon and send a nice little "Thanks, Cas." in our angels direciton. One that everyone can hear, of course, so they all know just how good a friend and ally Castiel has been.

Which leaves us with a case of each against all for the finale:
Eve, who no one really cares about.
Crowley, with an armee of monsters at his disposal and a big grin on his face. And while we're at it, can we have a big revealing explanation on Crowley's finger snapping? We know who he was before he became a demon, so he's obviouisly not an angel. But I still want this to mean something.
Raphael, who only wants to crush Cas and everyone else who ever pissed him off, and get the Apocalypse back on track, without caring too much about the rest.
Cas, struggling with his powers and the decisions he has to make. At his side Balthazar, who'll either protect his brother at all costs, or try to get him off the path he's on - I-pretend-like-I-don't-care Balthazar style of course - and will probably get himself killed in the process (even though I still hope and pray I'm wrong about this).
And finally Sam and Dean (and Bobby), finding themselves in the middle of it all. Dean loses his trust in Cas because he worked with a demon - which I don't like, and which is terribly hypocritical of him, but I do see it coming. And Sam... well, Sam's wall probably decides that this is the perfect moment to break down.

Chaos, destruction, and the worst possible place for everyone to be in. Welcome to Supernatural.
