UPDATE!
Hey everyone! Thank you for all the lovely reviews, I really wasn't expecting it! I'm sorry, but this isn't an update, I just wanted to reply to the reviews. A few of you have said you would have preferred it to have ended slightly differently and I know what you mean, because I wasn't all together happy with the ending either. I mean, I wasn't going to have Sirius going all shouty and storming off to Hogwarts in a rampage, because I think Sirius is more sensible than that, but I think I might have made him drop it a bit too quickly. My problem was that I didn't want to do anything that would change the plot of the proper book, so I couldn't really have them take any proper action.
Also, I wanted to say that I may be going over this story to edit and improve it, and I might have been persuaded to add a few more chapters ;) Updates won't be regular what with mock exams coming up and my final exams in summer, so if you would like check out my other story go right ahead! It's scenes (and missing scenes) from the books, but from other characters points of view. Including Mrs Weasley meeting lost little Harry at Kings Cross for the first time, and Lupin's POV of part of the Prisoner of Askaban.
Thanks a bunch you lovely people!
