05E10 - Fragments

Sam offers Andy a key to his apartment but she refuses. Duncan returns to active duty and requests to ride with Andy. Chloe and Andy are stopped while on patrol when a Parking attendant chases a car on foot after the driver didn't pay but moments later an I.E.D explodes in the parking structure which left one woman injured. A second bomb goes off in downtown, killing one and injuring 6, which makes the detectives think it's a mob hit aimed at eliminating Aiden Kelly, head of the Irish mob. When Duncan makes a rookie mistake he is handcuffed in a car wired with a bomb by a father seeking revenge. Someone from Sam's past returns and Gail makes a steady move towards her future.
