I admit to getting a bit confused about werewolves between SPN and Teen Wolf, so whatever I felt didn't fit I just handwaved or blamed on crossing shows in my brain. :)

I'm surprised no one brought up Lenore and her vampire pack.

And I'm glad Garth didn't die at the end of the episode. I wonder if his pack is going to be involved or mentioned in the new series at all -- is it some sort of setup saying that there are 'good' packs around?
