The way they did the promo for this episode, it looked they might actually have Billie the Reaper try to take Sam away. That's clearly not what happened, though. She was just there basically as a reminder to Dean that once they die, that's it. And this ties into some worrying speculations I have regarding season's end. I'll get to that, though.
I had so many emotions all throughout this. Seeing Sam get shot by one of the werewolves, and then that bastard telling Dean to leave him behind, and then finally trying to choke Sam to death. I was so waiting for that ass to get his. Yeah, I know he was so devoted to saving his wife (as an aside is it just me or did that girl seem really young? Like 18 young?), and some could try to draw a parallel between that couple and the brothers, but still. But he did end up getting his in the end, thanks to Badass!Sam. Dang, he really was badass in this episode. First, he survives the bastard choking him, then he kills those two other werewolves (were they actually werewolves? The woman kind of reminded me of a poor imitation of Ellen when the boys were first asking her about the cabin earlier on), drives himself over to the Impala and then meets Dean at the urgent care facility. Loved seeing our boy so badass! Jared was awesome here.
And now this brings me to Dean. I loved how Sam was still his first priority after getting shot, even with that couple in such a bad way. I loved how he refused to leave Sam at first, how he was still Dean's top priority and how he said he'd come back for Sam, even though he thought he was dead. Dean was in tears at one point too. Jensen did a great job of portraying Dean's devotion to Sam. He thought he was dead, and decided he had to make himself dead in order to summon Billie and ask her to bring Sam back. He even wanted her to take him instead. But oops, he learns that Sam actually isn't dead. She looks all ready to reap him but then the doctor brings him back. He talks to the girl at the end and tells her she's going to be back to normal. She seems so lost without her crazed, were-husband, though, and says she won't go back to normal.
And of course at the end Dean kinda, well, fudges the truth when Sam questions him about this. He tells Sam he knew he wasn't dead. Yeah, not exactly the truth.
To sum it up, I loved seeing Sam so badass here, loved seeing the lengths Dean would go to get him back (ie his devotion to Sam) even if it's the same old cycle they get themselves into, and even though I hated that guy for trying to kill Sam, I'm glad he got his in the end. One thing I worry about is any attempt to draw a parallel between the boys and that couple, and say that this is what will happen to them in the finale? Especially the lingering camera on Dean, as if to say he'll be just like that in the finale if Sam bites it & is taken away for good. Also the fact that we had that reminder from Billie about how they're gone for good. I almost hope it's a red herring because I would hate to see a Swan Song redux with no way of either of them coming back. :( Really hoping they're not making it this predictable.
