Third Watch: Ep 18 - Purgatory
Monroe is temporarily suspended after her gun is used in the course of a crime. Wracked with guilt and preoccupied, she accidentally rear-ends a car, causing an explosion that kills a child in the car's backseat.
Meanwhile, a combative Cruz confronts new firefighter and former cop J.D. Hart about their shared history, all of which intrigues Yokas.
As Davis comforts the grief-stricken Monroe, he must also make time to take the LSAT (Law School Admission Test) exam with Sullivan.
