I don't think I've ever laughed so hard during a Supernatural ep. LOVED IT. Funny because they referenced the X-Files and I never did like that b&w monster ep that everyone raved about. Now, this ep? Nothing but love, love, love. And more love! It was nice to smile all the way through an SPN ep.
And of course we all knew it was Lucy the whole time -- but what was up with all the thirsty, thirsty witnesses? I thought they were going to explain that somehow -- is that a known shapeshifter exposure thing?
