Just got done watching this episode.
I've been excited for this ep but it wasn't quite what I expected. Like some of you have said, I felt it was lacking something.
Jared and Jensen were both great. Sam saying he was supposed to wake up killed me. And of course seeing what Sam became w/o Dean........just going through the motions, etc. was heartbreaking.
The whole Trickster thing was kind of weird. I get him being ticked off at the guys and wanting to mess with them. But, the whole idea of it really being a lesson for Sam.......I don't know. I just don't see why he would be invested in that. Or even why ultimately he let the whole thing go. I don't know.
Maybe speculation about someone putting him to it is a possibility.
