Paul comes out of the shower with no shirt on and, tada! he has no evidence of his shoulder surgery at all. Not even a little puncture mark. He goes from all bandaged up and in bed to no scar and he would have NEVER put on his shirt the way he did so soon after shoulder surgery.
Oh, and how come he got dressed without first toweling off? His chest was soaking wet. Hmmm, maybe that was part of the miracle. I guess we just have to have a good look at his chest. That seems to be de riguere for the men on Days.
