This is another excellent chapter to this story.  Normally, internal narration, where the character catalogs his thoughts don’t work for me, but Harry is by nature introspective and often alone.  I believe that he would run through his thoughts this way.  You’ve given the reader a glimpse into his mind, without revealing everything. 

I was surprised at how well the conversation between Harry and Dumbledore went.   Would Harry really exercise his anger towards the headmaster so quickly?  That said, I feel the conversation showed Dumbledore as learning from his mistakes.  Allowing Harry the freedom to leave the Dursleys as soon as possible can’t help but speed the healing process. 

I’m glad that Harry focused on Sirius being cleared.  Padfoot deserves to be known as a hero, and now Harry won’t have to hide how much he meant to him.  Just that little smile was a good sign. 
Once again, I’m enjoying your work, and look forward to reading the next chapter.  I can’t wait to see him back with the Weasleys.  Thank you for sharing your creativity.
