I have not read the books, so please do not post any spoilers for "Deathly Hallows." Thanks! 
Now, I just watched my DVD of "Half-Blood Prince," and I have a couple random questions for those who have ready the books, primarily: What happened to _____ between "Order of the Phoenix" and "Half-Blood Prince"?
-Cho
-Lucius Malfoy
-Dumbledore's Army: now I realize this one was a result of what's-her-face taking over Hogwarts in OotP, but I was still hoping the kids would be around. HBP was really lacking a lot of the minor characters that have been around since day 1.
