Love what is going on so far. A few things I noticed;
1. H&H were sleeping together in Summer, now they're being separated. Seems incongruous.
2. I can't figure out the letters and decisions thing by Hermione. Why was she deciding again between Harry and Ron? What'd I miss?
Regardless, you have my rapt attention. Love the Sirius as an 8 year old thing and hope you have a little fun with it next time. Lots of potential there.
