Looking for an old Slytherin!Harry fic.
Think he befriended the little ponce, and called muggle-borns mud-bloods. Was really short-tempered at Halloween, didn't save Granger from the troll, she died. Harry went after the stone for some reason, but gave it to Quirrell for the promise of being left alone in the future. Quirrell stunned him afterwards, so Dumbledore wouldn't find out.
Think Harry was going to join in on the fun during CoS the last chapter I read.
Thought the writing really rough back then, so this fic probably isn't any good, But it has been bothering me for a few years now.
I know I found it on a c2 on FFN originally, was a newbie to the genre back then.
