Intro. You are an abnormal student... A lot of people highly dislike you because you are weird, and everyone assumes you don't have a Patronus, little did they know you do have one, but not like the ones that they would expect, you had a guardian, not a Patronus, which isn't summoned by a spell, more by a song... Snape is the only one that thinks you have potential for being a Hufflepuff, and during the battle with Voldemort who had learn deadly magic and able to summon dark creatures to his aid alongside the death eaters, except for Snape.

Hogwarts... Shock
