The Human Shield

S12 E7: Neela prepares for Gallant's (Sharif Atkins, not appearing in this episode) homecoming from the war, but her plans change when she receives a call from Iraq. Meanwhile, when Kovac and Clemente (recurring guest star John Leguizamo) disagree on how to save a patient's life, Abby gets caught in the middle. A police officer and a little girl are victims of a shootout, and Neela is conflicted about whether or not she should save the gunman's life. Recurring guest star John Stamos appears as paramedic Gates.
