I'm under the weather and not really up to doing the kind of review this episode deserves, so I'll do a quick drive-by. Hopefully I'll have something to say about Friday Night Lights later tonight.
I love the work Bob Singer did in this episode, laying down storylines that'll undoubtedly drive at least the rest of the first half of this season, if not the rest of the year. Sam's refusal to become the Yellow-Eyed Demon's right-hand man, not to mention killing the demon, has thrown the demon world into a chaos possibly worse for mankind that what might have played out if Sam had just stepped up to his demonic destiny. And now we know he was Azazel, not just any ordinary demon, and after the havoc that boy wreaked on Hex I'd keep an eye out for him, boys. Now the demons are all jockeying for power, as well as trying to set up shop in human bodies Earthside. What is Ruby's role in this? She helped Bobby set the Colt to rights, and has promised to help Sam save Dean from Hell. But what will she demand of Sam along the way? All signs point to bad.
