So, as I hope you are all aware, we are in the serious counting-down phase here. Two more months till... oh, come on, you know what I'm talking about... Harry Potter, Book The Seventh And Final.
For posterity's sake, this is what I think:
1. Snape is evil. Anyone who thinks otherwise is (not to be overly harsh here) delusional.
2. Dudley was born a wizard and Aunt Petunia had him Squibified. This is the terrible memory he relived in Book Six, at the beginning when you you-know-whats came to Little Whinging. (Being vague here in case you haven't read Book Six.)
3. MHH thinks that in the last chapter, in which we are told we will find out what eventually happens to the surviving character, we'll find out that Hermione will become headmistress.
