I saw Donna in Studio 60 as well. And I'm praying she makes a return to CSI as Annie. I would love to see her and Jim end up together. Paul and Donna have amazing chemistry on screen.
I also saw her in Studio 60 and mentioned she was Brass's girlfriend. I think that scared people in the room momre than if I shouted her name. That's weird, I've liked her ever since she was Picard's girly, too!
