I like your explanation for Hallucifer being part of Sam's mind, and how Cas 'took' the damage. You have a lot of thinky stuff in this analysis...And I love how you describe Dean's expressions making a whole conversation, because Jensen does that all the time, and it's why he is such a rivieting actor.

I'd love to read the trenchcoat scene original dialog--is there a link to the pages that were revised?
