I had to pick the shapeshifter because it's truly creepy to me that this thing can become anyone you know. (And this was the ep that broke my SPN cherry, of course.) AND that Jensen's marvelous acting made me a little sorry for the 'shifter. AND 'In-A-Gadda-Da-Vida,', which, hands down, is for me the king of wtf rock songs ever written!

But I almost picked the Benders. I kept thinking about it while I watched "Countrycide" from Torchwood, which is almost my absolute favorite; God bless those Brits, because it is such a balls-out, scary, bloody story, like one of SPN's best.
