When Michael jumps into the freezing cold water to save a man from drowning, he is dressed in his jogging clothes. After the opening credits, Michael is seen still performing CPR on the man in a room at Holt Neuro, but in this shot, Michael is perfectly dry, dressed in surgical scrubs, and with no visible sign that he was in the water. Since CPR must be administered continuously, it is highly implausible that Michael would have stopped to let someone else take over while he went to dry off and change into clean clothes.
