Pretty shaken up after the finale. Just got finished rocking back and forth on floor in fetal position, in fact. Took me a whole day for the shock to wear off. I'm still having trouble wrapping my brain around this. Oddly enough, I think I like Cas even more now, even though he's completely lost it... Anyways, have fun with this little piece.
It's something you never get used to.
How do you get used to having your family betray you? Why should anyone have to get used to that?
Dean doesn't trust easy. He doesn't trust easy, but he loves pretty damn hard. Because Dean's got the heart of a wolf- nervous and aggressive with snapping teeth, but loyal to those he loves. Loyal to a fault.
So it's not fair, Dean will think, that the people he trusts most betray him.
It's not fair, he thinks, that just when he's got his brother back, he loses Cas. And Cas tried to take Sam down, too. So maybe Dean's not going to have anyone. Maybe Dean is going to be alone. Lisa and Ben don't know him. Sam is fighting Hell in his mind, and how long can he stay sane? Cas is... Cas isn't Cas anymore.
Dean used to pray to Cas. Like he used to pray to God. But so much for praying, because for all that, all he has now is Cas-Who-Thinks-He's-God.
Forgive him for refusing to pray to that.
