 * This is the first episode to feature multiple alternate universes.
 * This is the first midseason finale since Season 11 to not feature Castiel though Dean believes he has talked to him on the phone.

 * Jack says Derek Swan is a descendant of the Black Elk. The Black Elk was a famous medicine man of the Oglala Lakota (Sioux) who lived in the present-day United States, primarily South Dokota. The details of his life were recorded by amateur ethnologist John Neihardt and published numerous times, most recently in 2008. Black Elk converted to Roman Catholicism near the end of his life, and reared all of his children as Catholics as well.
