Soo, that episode was boring until the ending totally made me cry. Dean was so vulnerable and almost crying and he looks so small and alone in his big room and HE MISSES CAS SO MUCH, AND, OUCH!! ♥
However I am very disappointed in what Sam said in the second to last scene. I don't want this to come off as bashing, because I do love Sam. But two episodes ago he was optimistic and wanted to bring that optimism to Dean. He said he would show Dean the light at the end of the tunnel. And now he's literally just like, "never mind, you were right. There's no light." He's back on the 'this life is a death sentence' train when like Dean said, HE PROMISED. I hope he comes back around, because that optimism was so refreshing and was really what I was hoping this season was going for.
Aaaand now to stay up all night writing the short story I have due in the morning. Fun.
