Thanks so much for your critique--particularly about the narrative structure--I did feel that I was giving a lot of exposition, and I need to think about other ways of getting background information out without being too pedantic.
Glad you liked the interactions--I actually really like Ron most of the time--he can often be the quiet support that Harry needs, but sometimes his knee-jerk reactions are too priceless. You just have to take advantage of them!
I do sooooo adore bottom!Snape--all of that self-control, passion, and intensity just begging to be taken!
I do have a sequel in mind--have to get further in a few other stories, but will probably start it early in the new year.
