Five-O (Better Call Saul)

In a flashback, Mike arrives by train at Albuquerque's Alvarado Transportation Center. After re-bandaging a fresh bullet wound in his shoulder, he meets his daughter-in-law, Stacey (the woman he previously saw outside her house)[lower-alpha 1], and her daughter, Kaylee. Stacey and Mike briefly discuss the death of Matt, Mike's son and Stacey's husband. Stacey questions whether Matt might have been involved in something illegal, based on his behavior during their final encounter, but Mike brushes off her concerns. After the meeting, he questions a cabdriver as to "how well" he knows the neighborhood, and is later seen having his shoulder wound treated by a local veterinarian, Dr. Caldera, who inquires as to whether Mike might be interested in any "work", which Mike declines.

The police officers who met Mike at his house[lower-alpha 1] are from Philadelphia. Detectives Sanders (whom Mike knows) and Abbasi attempt to question Mike, who requests a lawyer and gives them Jimmy's card. Mike asks Jimmy to "accidentally" spill his coffee on Abbasi so he can steal Abbasi's notebook and investigate how much the police know about him, but Jimmy declines. In the interrogation, the detectives explain they're investigating the death of Mike's son Matt, a rookie police officer who was ambushed and killed in 2001 when responding to a shots-fired call. In addition, Matt's partners, Troy Hoffman and Jack Fenske, were shot and killed in a similar ambush six months later. The detectives know Hoffman and Fenske were dirty, and suspect Mike of killing them since he left Philadelphia shortly after their deaths. Jimmy moves to end the interrogation and spills his coffee on Abbasi. Mike pretends to help Abbasi clean his jacket and steals the notebook from his breast pocket.

At home, Mike discovers from the notebook that Stacey summoned the detectives to Albuquerque. She tells Mike that after she arrived in Albuquerque, she discovered several thousand dollars hidden in the lining of one of her suitcases. She decided to report it, hoping it would lead to the identification of Matt's killer. She suggests that she believes Matt might have been dirty, which angers Mike.

In a flashback to Philadelphia, Mike breaks into a police car parked outside a bar. He then enters the bar, and after a few drinks, confronts Fenske and Hoffman, telling them "I know it was you". A few hours later, Mike is the last customer at closing time, and announces to the bartender that he plans to move to Albuquerque. As he staggers home, Fenske and Hoffman drive up in their patrol car, offer him a ride, and help him into the back seat. They take his handgun and ask him what he meant when he talked to them earlier. Apparently still drunk, Mike tells them he knows they killed Matt. They drive to an abandoned factory. Fenske and Hoffman plan to kill Mike and make it look like suicide, but Mike reveals that he's not really drunk. Fenske attempts to shoot him, but the gun Fenske took from Mike is empty. Mike shoots Fenske three times using the pistol he hid in the backseat earlier and retrieved while pretending to be drunk. Hoffman tries to draw his pistol, but Mike's shot hits him in the head. Fenske then draws his service pistol and fires twice, with one round hitting Mike in the left shoulder. Mike returns fire and hits Fenske in the neck. Fenske tries to crawl away, but Mike steps on his leg to flip Fenske over. Fenske raises a hand as if to beg for his life, but Mike kills him with a shot to the head. Mike picks up his unloaded handgun and walks off, preparing to depart for Albuquerque.

In Albuquerque, Mike admits to Stacey that corruption was rampant in Matt's precinct, including Mike himself. When Hoffman started accepting bribes from a gang he offered to cut Matt in. Matt asked for Mike's advice, and Mike suggested that not taking the money would mark him as a whistleblower, which could endanger him and his family, so it would be better to accept it. Mike admitted to Matt that he participated in the corruption, leaving Matt upset that the father he looked up to is a criminal. Matt ultimately accepted the money, but didn't spend any, yet Hoffman and Fenske murdered him anyway because his hesitation before accepting made them fear he'd turn them in later. Mike is tormented over corrupting Matt for nothing, saying in tears of anguish "I broke my boy!" Stacey asks who killed Hoffman and Fenske, and Mike says "You know what happened. The question is: can you live with it?"
