I was trying to think of a plausible explanation for why they brought a nurse with them. I haven't seen the video of the two of them walking into the Hard Rock. Did you? Did Anna look sick?
I don't think she looked ill, she was wearing sunglasses, had on a trench coat and slacks and was walking in under her own steam alongside HKS. You couldn't miss the rock on her finger. We know from Birkhead's testimony yesterday she had a thing about ten carat rings.
