Holy crap those children were creepy *shudders* That's the closest we've been to a properly scary episode in ages!
Mini!Dean was a work of sheer genius! A total counterbalance to the creepy changeling children. Is it wrong that I would want someone to teach my kids to kick a bully in the balls?
And Buffy is a demon. Verrry interesting. She's kind of annoying with her vague smugness though. I hope Sam bitchslaps her very soon. After she's helped save Dean (assuming she's not lying about that, which she probably is)
All in all a good episode. I liked!
