Very few things, because I'm actually rocking back and forth here:
1. Could they get any more blatantly Dean/Cas shippy? (I shall ignore the "you're like a brother to me" line, because, yeah, really, more like husband.) They couldn't be more clear if the drew hearts for each ... oh, wait. ;o)
2. Cas. I knew he wasn't going to turn evil. He's not, he's just horribly misguided, directionless. But that's what freedom mean, isn't it? It also means the freedom to make wrong choices and to learn from them. He's walking on the road paved with good intentions, and if he'd relayed the whole story to Dean, Dean would have understood, but Cas never once tells the whole story, now does he?
3. Dean's line about having to stop Cas. I said this to
4. Cas' hopeful face when the boys apologised and Dean's reaction to his slip with the Superman line. Oh, God. They break me.
The finale will break me. I fear Cas doing some tremendously stupid shit to reconcile with Dean. I foresee some stupidly self-sacrificing move on his end.
Also, let me go capslock for a moment here: WHY THE HELL ARE THEY PUTTING THE REALLY INTERESTING STUFF IN THE LAST FOUR EPISODES?!??!!
To sum it up: Cas, please don't die. Dean, please don't go against Cas in a fight. Please forgive him before there's an event after which you no longer have the chance to apologise.
AND CAN SOMEBODY PLEASE HUG THAT ANGEL AND GIVE HIM HOT CHOCOLATE; A BLANKET AND A BISCUIT? Damn, but he needs it.
