Brin: I saw this cool post on tumblr
where this chick was saying that she didn't mind so much that only the seventh book was split into two movies.
Isla: What was so cool about it?
Brin: She made a connection between how most people thought there would be seven movies when there turned out to be eight, just like with the fragments of Voldemort's soul. Everyone thought there would be seven pieces but there turned out to be an eighth piece in Harry.
Isla: Oh. My. God.
Brin: I know right? I had the exact same potterpiphany!
