Supernatural, brought to you by the Twilight Saga? Really? I realize Sam and Dean wouldn't kill the Cullens because they don't eat people, but still. Supernatural, sponsored by vampire movies? That's just a little odd.
Also, it's no surprise that Dean would freely bet years of his life away and not care. He a.) has no sense of self worth and would willingly sacrifice himself for others, b.) doesn't think he's going to live that long, and c.) knows the angels will just bring him back to life. Along those lines, old Dean was pretty awesome. I kept imagining Jensen saying the same lines the older guy did and was very very entertained. It was awesome. Can we still have show when Dean is that old?
I did rather like both of the MOTW in this one. Patrick had me at "It's barely linty" (and really won me over with the clap) and the girl helped the boys out. I'm glad they didn't have to slaughter them.
