Pretty good update, I especially liked the threatening conversation with Dumbledore. Hopefully Harry will continue to spend his holidays with the Eye rather than with Sirius or the Weasleys. Not only is his time with them more productive, they don't have nearly as much of an agenda. Sirius is probably a bit unbalanced at the moment, courtesy of Azkaban, and isn't the best of guardians, while I just plain don't like the Weasleys. From your treatment of Ron so far, and your feelings on DH, I know not to expect him to be stuck there.
Looking forward to more.
