Wait a second. I have some questions. He has no goals? How did he get through life to be almost an adult and not have any goals or dreams? Was he a log in Hogwarts all those years? he's going to be graduating in june. what the heck is he going to do with his life? if he has no motivation, and there's nobody in his life, why is he still in Hogwarts going through school? What motivates him to get up and go to classes, in that case? And why is he so depressed all the time? What's his deal? If this is the way he's always lived, he'd be used to it. He's "getting farther from reality'? What does that mean? Is he delusional? Does he hallucinate? When did that start and why?
What are the characteristics that make him a good Slytherin or a good Ravenclaw, b/c to me he looks like a Hufflepuff.
Second, if his family is dead and he doesn't remember them, how does he know he's a pureblood. How does he know what class he comes from? who the heck raised him? was he raised in an orphanage? how is it he is middle class? and where does he have any money for a broom at all? i'm really confused about his history.
he needs a third character weakness as well.
Please think him though more and develop him more.
