Trivia

 * The episode was watched by 1.75 million viewers and got a 0.6 rating.
 * This episode features the first time an angel's wings have been seen burned into the ground following their death since Castiel killed Rachel in Season 6's Frontierland.
 * This episode features a plot twist where the supposed good guy, Ishim, turns out to be the bad guy while Lily Sunder is in fact the good girl.
 * Previously, it was stated that angels had not appeared on Earth for approximately 2,000 years. The sole exceptions were Gabriel, Metatron, Grigori, Reapers and Cherubim. The fact that Castiel had appeared on Earth 100 years ago on Heaven's orders implies that there has been another retcon to the story.
 * Showrunner Andrew Dabb did state that the writers intended to re-write Castiel's backstory. This maybe the first example.
 * This episode marks the first appearance of regular angels since We Happy Few.
 * It is revealed that before Jimmy Novak, Castiel had used a female vessel for an unknown period of time. He eventually stopped using this vessel for reasons unknown at some point in the past which led to him needing Jimmy to interact with Dean when he returned to Earth in 2008.
 * Chronologically, this makes Castiel the first known angel to use vessels of different sexes. The other angels were Raphael and Hannah.
 * Four actors/actress who took part in this episode, also portrayed other characters previously. Ian Tracey portrayed Lee Chambers, Nils Hognestad portayed Chris the hairdresser in Season 7, episode Shut Up, Dr. Phil, Tiara Sorensen portrayed Greed and Jessa Danielson portrayed the fake vampire victim in Season 6, episode Live Free or Twihard.
