Hurtful Remarks Blocking

Ok, here's the blocking for one character in a dialogue sequence I'm doing (personal project). It's a line from Black Books, a British television program from the mind of Dylan Moran. It's wonderful. I've only blocked in the one character so far, as I'm not entirely sure what I'm going to have the other character do until the end when his lines come up. I mean, I have some ideas, but I need to do some thumbnails to really nail down the my nebulous ideas.
