Great start to the story mate, why the hell didn't McGonagall listen to Harry that he didn't know how Gabby got into his bed? It's not like he did anything, shame. :P So Harry as got her as a companion, I think there is more then the teachers are letting on.
What is going on with Dumbs, what has he got planned for Harry?
Oh I like that Harry is free from his family:D
PLEASE update soon.
