Plot hole: When Sam and Dean realise they need to destroy the hook to stop the Hook Man, they find out that it has been reforged into something else. They state it needs to be set on fire to stop him, but if it was melted down and reforged then it has already been set on fire and the Hook Man shouldn't be latched on to it in the first place.

Supernatural (2005)
1 plot hole in Hook Man - chronological order
Hell House - S1-E17
Visible crew/equipment: When Dean, Sam, Ed and Harry have just shot Mordechai, the cameraman's arm is visible on the right-hand side of the screen. (00:33:30)
Dean Winchester: Driver picks the music. Shotgun shuts his cakehole.
Trivia: At the beginning, the cabin looks very similar to the cabin in The Evil Dead, even the swinging bench (although on the opposite side of the door). And the girl calls out the name Ashleu, Bruce Campbell's character in Evil Dead.
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.
