Freddie Delgado is shot dead while driving his car through a parking structure. Tommy finds photos of young girl in the victim’s automobile. The pictures are of a six-year-old he accidentally shot during a robbery years ago. The little girl’s dad, Paul Winters, vowed to kill Freddie. He planted the photos so the guy wouldn’t forget what he did. He’s not sorry Delgado is dead, but claims he didn’t kill him. Winters lets the press know that his daughter was taken by a monster. The guy got what he deserved. People need to pay for their actions one way or another.
The statement made by Paul Winters goes viral. It sparks a wave of vigilante justice throughout the city. Megan and Tommy visit the victim’s wife, who says he gave up his gang life once he had a baby of his own. She also says Paul Winters was harassing her hubby, but the distraught dad alibis out. Tommy is happy to say that karma killed their victim. In other news, Kate is preparing to announce her run for public office. Megan promises she’ll handle the vigilante case while she preps.
Megan is upset to learn that her mother, Joan, is selling her house. She finds an old photo of her dad along with some of his belongings. Megan and her mom get into an argument about the box of items she found. The fight is cut short when duty calls. A woman at a halfway house is found dead after having had acid thrown in her face. She’d been locked up in the past for doing the same thing to someone else. The cops pay a visit to Susan Hart, the wife of the man she killed, while Megan has a chat with her therapist, Trent Marsh (guest star Henry Ian Cusick). The guy asks her if she lost someone to suicide when he sees her perusing one of his books. Megan avoids answering the question.
Marsh tells Megan that he specializes in grief counseling. He gives her a copy of the book she was skimming. Later, Joan shows up with the box from the attic. She used to tell others that her husband died of a heart attack. She hid his suicide note in that box. Joan gets frustrated when Megan again voices her belief that her dad may not have killed himself. She’ll never stop believe in that possibility. Lacey lets her mom know that perhaps she could see therapist to talk about things. That’s why she calls Dr. Marsh.
