Yes, they kept the lines about the sister who died for love, and the actress playing Kate delivered it in a very straightforward way. After she'd finished, everyone paused for a second, and then went back to being clever and witty. It was a very odd moment. Only Rosaline seemed to react at all, with her question about Kate's meaning, but there wasn't much more than that.

I'm very happy to have seen it -- I was just incredibly lucky, since I knew someone with an extra ticket. I got there and they were completely sold out.
