Revealing mistake: When Dean cuts leviathan-Dean's head off, if you look closely you can see that a) the decapitated head disappears while it is still in the air, and b) when the body recoils, its hands disappear.

1 revealing mistake in Slash Fiction
Factual error: When Sam and Dean show up at the crime scene to investigate, they are stopped by a woman wearing digital Army ACU's. She introduces herself as Sergeant Miranda Bates, even though she has rank insignia on her cover and her chest that identifies her as a PFC (private first class). (00:14:05)
Dean Winchester: Driver picks the music. Shotgun shuts his cakehole.
Trivia: The inscription on John Winchester's gun is Latin, translating to "I will not fear evil."
Question: Why did Sam just stand there and watch Dean get turned into a vampire? And then smile about it?
Answer: Over the next few episodes, it is revealed that something is not quite right with Sam - that his soul is missing since he returned from Hell, and he does not feel any emotion or attachment to his brother.
