All hail her royal highness, Princess Platinum! IJUSTTHOUGHTOFTHEBESTEPISODESTORYLINEFORTHIS! OK, hear me out. Or, uh, I guess, Read, me out.... Anywho, So all of the mane six (or five anyway, since twily is an alicorn) who are present at a thing get bestowed alicornhood by princess celestia. Rarity was not there due to her making a super special order for a super fancy pony in Canterlot. Nopony noticed and so she did not get any wings. When she finally finishes the order, she goes to the thing. Nopony is there anymore. She feels neglected. And lonely. She notices all her friends are being all high and mighty around her, because she is not an alicorn. She retreats to her shop, where she sulks for a bit. She discovers her Princess Platinum outfit in a dusty old box. she styles her mane and gets so caught up in her loneliness, she believes she is Princess Platinum. And thats when Discord appears. he rejoices in the fact that his plan worked. He looks at the screen and says, yes bronies. He reveals that he was the one who made nopony notice her. He was the one who made her delusional. He was the fancy pony the order was for... I've got nothing after that. Good idea, no?
