Whilst restocking potions at Sugar Cube Corner, Potion Nova runs into Rarity. Rarity insists Potion Nova gazes upon upon her gems. She makes Potion Nova regret ever declining her offer..... ---- Potion Nova is written as an alicorn in this story as opposed to being a unicorn. She was originally shown as one in the show and I honestly think it's wasted potential that she wasn't one.
