Previously - Mary burned, John disappeared, the wicked curved blade made a solitary appearance (sigh), Dean needed Sam, Jessica burned, John left his journal, Sam wanted revenge, and there were more classic lines in 3 episodes than most shows have in 3 years.
This episode is classic Supernatural to me. The brothers work together to fight evil and save the day. Humor is mixed in well and I consider this episode one of the best for one-liners. Kuddos to the writers for a great, if unbelievable, script. It's also fun to see the brothers get an unquestionable, no strings attached victory against evil, something sadly lacking in recent seasons. All in all, it's a solid, fun monster of the week story I always enjoy rewatching even if it's not in my top 25 episodes.
