Help me pick a scene, dear flist!

I have signed up for the hp_art_project and if you're not familiar with it, it's a cool idea, that each chapter of each book is assigned two artists, who draw a scene. All the pics are then compiled into a book and sent to JKR.

My assignment was Book 5, chapter 37.

Oddly enough, Snape is not having sex with Harry (or anyone else) anywhere in that chapter.

WHAT SHOULD i DRAW???

Plz to be taking a peek there, and letting me know what you think I should do.

There is a lot of talking and not a lot of doing in this chapter, and one cool scene, where Harry throws a bunch of stuff around DD's office would be a fekking NIGHTMARE for me to draw, because I suck at all things linear and vanishingpointey.

All suggestions are welcome!

Thanks in advance.
