I saw that same look when he asked her if she was jealous. She flew HOT. I think that is a really, really soft spot with her. SHE will define the relationship, SHE will decide when the relationship is over and SHE is never, ever the one rejected. She might as well have a big, red, shiny button on her back that say 'PRESS HARD HERE.'
I was also thinking about her playing the sick card. FWIW, I really don't think she will. Most "normal" people would do anything in the dang world to avoid going back into that cross with JM. But this is JA. And this is all about HER. She's not gonna miss a minute of it! Why, all she needs to do is just get back up there and set him straight! Surely all the world fall in loooove with her! They'll probably name the courthouse after her!
