During the episode Hearth's warming eve Princess Platinum (Rarity), after being rude to by Commander Hurricane (Rainbow) , declares she"Won't be spoken to that way" and goes to leave, putting her crown on wrong as she does so. It's one of my favorite parts of the episode, but so many people overlook it because it's sort of hard to spot.
Ooooooh, it's been ages since I saw that episode. Thanks for explaining!
That's alright! I'm glad I helped!
