wow. After reading the entire presentation and thinking back on my own ideas/feelings of the HP series, a whole new outlook as to what will happen (and what has already happened) has been revealed! I'm a big fanfic reader, and it's amazing as to how the stories I've read that incorporated bits of your ideas seemed to ring more true than others (ie where Harry/Snape must not only work together towards defeating Voldie, but that forgiveness and understanding must develop to a certain degree between them to fulfill their quest/destiny etc)
I also had never realized the extent of Harry's alienation towards Ginny. I always thought that his cold to hot temperment towards her were a bit off. The glaring fact that Harry couldn't have given a second thought to Ginny for the first five books then all of a sudden she's everywhere and he can't stop thinking about her seems a bit iffy to me. But taking a step back from the romantic aspect of their relationship and realizing that they never *talked* about anything (important) and that Harry was most likely *never going to* puts a dark cloud over any change in their relationship, past the she's his best mates little sister.
There seems to be a much better basis for a Draco/Ginny ship (not just because I'm an obvious fan of this ship) but because Ginny has more of a history with the Malfoys than she does with Harry. That diary didn't pop up out of nowhere, and she definitely didn't forget about it after it was gone.
Anyways, that's my two cents. Love the presentation, wish I could have been there. Love your stories. Can't wait for your next post!
