Normally, I am a spoilerphobe for SPN, but I do watch the previews at the end of the episodes and I have watched the preview for SPN's episode next week a few times now.
Look, I am not a fan of vampires. They aren't my fave monster. But Dean as a vampire? That is freakin' hot.
Don't kill Lisa, Dean!
And what the heck is Sam smiling about? *suspicious*
I love it when supernatural things happen to Dean. Sadly, I don't anticipate any Sam angst over Dean, which is what I am always searching for. Not with him being emotionless, but the episode still looks interesting.
