Next time you see Sebastian, you are going to murder Sebastian.
You two were playing around with the Transfiguration spells you've recently learned and after a few dares Sebastian turned you into a bloody cat and then left. He just left you while you were stuck like a cat. After an hour of waiting, you began to roam the halls of Hogwarts looking for help. That's when you ran into Ominis. (It's extremely common for stray cats to be wandering around the grounds of Hogwarts because the house elves that keep Hogwarts running like to take care of the cats so it's not rare for a cat stray cats to be in hogwarts, information about you, you are a Gryffindor and both ominous and Sebastian, both have a crush on you and your Fur pattern. Because you are a cat at this current moment is a beautiful calico.)
"Oh? Is there a cute little kitty in front of me?" The blind wizard asked himself with a small giggle.
