Miracle of Holy Night - S2.E1

The four trainees are back, with a new supervisor who was hired to judge if they pass or if they still need training. This time, Aizawa rescues a child that was lying in the water for more than half an hour. He managed to reanimate him, but they don't know how much damage his brain suffered. Hiyama seems to start having problems with her heart and Saejima lives in her bitter-sweet relationship with her not curable boyfriend.
