Synopsis.
A.J. is expelled from high school for stealing answers to a test. Tony, enraged, decides to send him to military school. A.J. is interviewed by the administrator of the Hudson Military Institute, who lays out the rigorous schedule for students. Carmela believes they will train him to be a "professional killer"; Tony counters that he will be learning discipline and respect. As A.J. prepares to leave home, he puts on his dress uniform; both parents sincerely admire his appearance, but he looks at himself in the mirror and, in tears, asks not to be sent away. As his mother is adjusting his dress, he suffers a panic attack and collapses. Tony tells Dr. Melfi that his son has inherited his "putrid gene", and he cannot send him to military school.
Seeking intelligence about the DiMeo crime family, the FBI decide to go through a woman, and send Agent Deborah Ciccerone on an undercover mission to befriend Adriana. Danielle, as she calls herself, easily gets talking to Adriana in a dress shop. 
Paulie is in dispute with Ralphie about the division of proceeds from a robbery and insists on a sit-down. He claims $50,000; to his shock and dismay, Tony awards him only $12,000. Paulie later speaks quietly to Johnny about his dissatisfaction with Tony, and offers his services to Johnny's boss, Carmine Lupertazzi. 
Jackie Jr. is forced into hiding at a Boonton housing project after his failed robbery at Eugene's poker game. He calls Tony, pleading for help; Tony rebuffs him. Tony again expresses his confidence to Ralphie that, as captain, he knows what to do, but he must decide in a "timely fashion." Ralphie makes his decision: when Jackie leaves the apartment to get some air, he is shot in the back of the head by Vito. It is said that he was killed in a drug dealers' dispute.
At Jackie's visitation, Meadow cries uncontrollably when she sees him in his casket. Tony and Carmela are embarrassed when Rosalie notes the low attendance rate; the funeral has coincided with Super Bowl Sunday, a busy betting time. At the funeral, Silvio and Christopher are arrested for illegal gambling. During the reception at Rosalie's, Meadow and Kelli, Rosalie's daughter, argue bitterly about who killed Jackie; Meadow seems to believe it was a drug dealer, while Kelli insists it was an Italian. 
At the wake at Nuovo Vesuvio, Silvio and Chris enter, having quickly made bail. Ralphie has begun to distance himself from Rosalie; he and Janice ostentatiously embrace. Junior, no longer under house arrest, sings the Italian love song "Core 'ngrato", moving some of the men to tears. Meadow, drunk, throws pieces of bread at Junior while he is singing, then quickly leaves when she sees that her father has noticed. He confronts her in the street; she tearfully denounces the funeral proceedings as "bullshit" and runs away. Tony returns and puts his arms round A.J. and Carmela as they listen to Junior sing.
