She was having troubles with her hands when she was playing the piano. And then she was showing how her hands were shaking but not all the time. Jack is the only one she has told. He noticed her hands shaking. She also mentioned things like remission, flares, etc. She also told Jack that there were things happening for awhile but she put it off to getting older, etc. I believe. I bet they will find a way as they always do. What do you think?
