I agree with so much of this. But gosh that Purgatory conversation though, I guess I saw it so differently, Sam didn't say that he didn't try to find out what happened to Dean. He said that he shouldn't have stopped looking. Which to me, means that he did look. Just like we fans always thought he did, because Of Course he would have. He just never was clear about it to Dean because Dean was so grumpy in the first half of season 8. So I'm super happy about them being honest about Purgatory freaking finally. The way Dean actually listened, actually made sure Sam knew he heard him made me so happy. Because that's where the true grace of forgiveness is between two people like this who love each other beyond reason.
