Factual error: When Sam and Dean are showing Jo pictures of H. H. Holmes' victims, the last picture was a victim that was not his. The final black and white is Jack the Ripper's third victim, Elisabeth "Long Liz" Stride.

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.
