Sam's storyline sucks even more than Dean's.
Actually they both just suck out loud.
I'll probably get a lot of grief for this but the season finale with the shooting of the YED felt...off. It lacked the ooomph necessary to convince me he's dead which has led me to speculate that he's not totally gone. I just have a funny feeling in my stomach we haven't seen the last of Mr. YED just yet.
