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.

Sam Winchester: Why'd you let me fall asleep?
Dean Winchester: Because I am an awesome brother. What did you dream about?
Sam Winchester: Lollipops and candycanes.
Trivia: The inscription on John Winchester's gun is Latin, translating to "I will not fear evil."
Question: Not long after first meeting angels, it is established that they do not have genitals, or "junk" as Dean puts it. But in S06E10 Castiel gets an erection while watching porn and in S08E22, Castiel is required to kill a nephilim, the offspring of an angel and a human. If angels do not have genitals how are these two things possible?
Answer: Angels themselves may not have genitalia, but their vessels do. Nephilim occur when an angel in a vessel reproduces.
