wanted to take a hard line on Bayliss's cousin who killed a Turkish exchange student, and also said that Bayliss lacked an understanding of "his dark side" so would do poorly in his job. Yet Pembleton also saved Bayliss from being charged in an incident that could have been interpreted as robbery, and once told him that he was the only person he trusted other than his wife, Mary. While Pembleton saw the world in strict black and white terms, Bayliss was far more open to accepting the shades of gray present in police work. That said, the two ended their partnership for a time in the fifth season, partly due to Pembleton suffering a stroke. Bayliss stated that Frank's rhythm was "off" after recovery, but there were also hints that he had come to prefer working without him. In addition, he felt uncomfortable with Pembleton after he told him how he (Bayliss) was sexually abused in childhood. The case in the episode featuring his admission ("Betrayal") involved a mother who allowed her boyfriend to beat her daughter from a previous marriage and was pregnant with the new boyfriend's child; Pembleton showed some sympathy to the woman's story, while Bayliss repeatedly and forcefully berated the woman for her reluctance to stop the ultimately-fatal abuse. Later, he returned to partnering with Pembleton due to Mary leaving Pembleton for a time. While working on a case in which a teenage girl murdered the stepfather who beat her mother, the two had very different views: while Pembleton is far more sympathetic to her, Bayliss is determined to see her charged with murder. Pembleton sees Tim's personal involvement and assures him that it is not his fault that he was abused. Following his stroke, Bayliss treats Pembleton in the same cold manner, often refusing to listen to his theories and indifferent to any attempts Pembleton made towards repairing their relationship, although this animosity had all but disappeared by the end of the fifth and start of the sixth season. Pembleton left the force shortly after Bayliss was shot by a member of Georgia Rae Mahoney's gang in a gun battle. Pembleton met Bayliss's mother, Virginia, while Tim recovered from surgery. She told Frank what Tim thought of their friendship: "He thinks the world of you. He says you're his friend. He says you're not a person who has friends, but he's your friend." Shortly
