Jaime 🏳️🌈✨’s review published on Letterboxd:
at the end of this film we get a cameo from amber, richard and the baby from a christmas prince at margaret's coronation, meaning that this film enters the canon of the acpcu (a christmas prince cinematic universe) along with the knight before christmas. HOWEVER in the first film we see that they're watching a christmas prince on netflix, which only adds more evidence to my theory that within the acpcu a christmas prince is a documentary trilogy about the royal family. AND with this being set in the same universe as the knight before christmas, we can assume that brooke is yet another doppleganger. this will obviously all be confirmed when we get the avengers: endgame of the acpcu set in aldovia with all the vanessa hudgens dopplegangers uniting to take down whoever wants the throne this time.
