This week: Julia questions herself after a tough patient consult, Sam and Gates finally kiss, Pratt can't commit, a man with a troubled past saves the life of a young boy who nearly drowned, Skye and Dubenko are rudely interrupted, and a hockey game between the surgeons and ortho docs ends in a good old fashioned 5v5 fist fight.
