Great acting from Jared (Sam) and Jensen (Dean), but I really did not like Corbin. When Sam got shot and was being patched up by Dean, Corbin kept pushing Dean to untie them first. I knew right then, that was a bad sign... The gunshot is more critical. Corbin could have waited 10 seconds. Then later on, he felt justified killing Sam in order to convince Dean to leave Sam behind in order save them... He's been dishonest from the beginning of the episode, and was lying throughout. And finally, Corbin then wants to change his girlfriend into a werewolf when she clearly did not want that. I know it's an impossible situation, but this Corbin guy really went too far and ruined the episode for me.
