i can't wait to see:

_Umbridge's face when Hermione & Harry have taken her to the forbidden forest to the centaurs...that whole scene.
_The DA scenes.
_The whole part at the Ministry, especially the brains with Ron, and the globe shrinking Avery's head to a baby. tee hee...
_Firenze teaching in his forbidden forest classroom.
_Occlumency lessons with Snape....

...and so much more.

This one might be the bloodiest of them all...
