Continuity mistake: In this episode, Dean says he was born in 1979. In the first two seasons, in the flashback to their mother dying, that's in 1983 which would make Dean 4 years old. He's definitely not 4 years old in the flashbacks.
Supernatural (2005)
1 mistake in In the Beginning
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.
