I caught minor typoes and punctuation problems throughout (not enough to jar my enjoyment, just to stand out). For instance:
Remus for Merlin’s sake man quit shivering when I say Voldemort your embarrassing yourself!
Should be punctuated:
Remus, for Merlin’s sake, man, quit shivering when I say Voldemort; you're embarrassing yourself!

Thanks for the comment I had it punctuated differently but didn't want to use commas excessively.
BTW: I've found that having Word speak the story has helped me catch word usage errors now I've just got to use it on the entire part not just where I'm concerned.
