During Monday's 311 conference, Hooten calls Dr. Stewart Delany (guest star Ioan Gruffund) to explain how a careless mistake killed Delany's young patient. But the outcome of the conference leaves the hospital's surgeons conflicted. Sydney and Villanueva operate on Keith Harriman (guest star Lukas Behnken), a young man with extensive injuries from an apparent suicide attempt. Sydney and Buck wonder about the resources wasted on those who cannot or do not want to be saved. And Mark Ridgeway (guest star Eyal Podell) returns, determined to make Ty and Tina pay for their adultery.
