- Content Leak: The Dutch version of this episode was released in mid-August accidentally by a Netherlands station (along with the remaining episodes of the season), which was quickly taken down. The English dub was eventually leaked on September 4.
- Jossed: A rather dark example, but for many years fans assumed that Celestia and Luna would die before Twilight becomes the new ruler of Equestria. By the end of this episode theyre still alive and well. Word of God even stated that they never intended to kill them off to begin with since it wasnt that kind of show.
- Meaningful Release Date: This episode broadcasted officially on October 12, 2019, a mere two days after the first episode's airing nine years ago.
- Short Run in Peru: The rest of this season, including this episode, aired early in Ukraine on September 24, 2019 on PLUSPLUS. The episode was also released on the same day to nc+ GO's on demand service in Poland.
- What Could Have Been: An early concept for this two-parter would have had Twilight being so disillusioned by the loss of friendship in Equestria that she would have become corrupted (taking on a form akin to Midnight Sparkle), and attempt to force the ponies to be friends again.
