I agree completely with all this. One of the things I like best about show is that whenever the characters are being dicks, it makes sense for them emotionally. I kinda revel in calling Sam and Dean out whenever they're being assholes, not cuz I'm mad at them, but because I enjoy watching their emotional journey...or whatever. You're also right about how Dean totally wasn't screwed up enough in season 4. I'm glad the 5th season is more realistic.

Heh, or maybe it's force of habit. Anyway, I'll forgive him :P
