I loved the new chapters! It's interesting to see the dynamics between the two groups. Personally I can't wait to see what happens in regards to the fake Moody and Snape.
I'm having fun throwing the headstrong Gryffindors in with the more reserved Slytherins and watching them play nice because Harry's decided to be a "grown up" about it. It seems like there'd be lots of misunderstandings, since they're so very different, but if they find a little common ground they get along all right (e.g. Ron's fascination with Crabbe and Goyle running betting pools)
