And Then There Were None - S6-E16
Revealing mistake: Samuel is very much dead, laid out on the table in the canning factory employee lounge, but as Sam stands over him, talking about whether or not it was right to gank him, you can see Samuel's chest rising and falling as he breathes. (00:26:30)
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: 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.
