"The Knight in White Satin Armor" is the 12th episode of the second season of the HBO television series The Sopranos. It was written by Robin Green and Mitchell Burgess, and directed by Allen Coulter, and originally aired on April 2, 2000.

Pussy turns against Tony, resenting the way he has been treated, and begins to behave like an FBI agent. When Christopher and an associate plan to hijack a shipment of Pokémon cards, Pussy spends the night trailing them. In the morning, a sleep-deprived Pussy crashes into another car, injuring his knee and knocking down a cyclist. Skip Lipari gets him out of trouble but angrily rebukes him: his duty is only to collect evidence against Tony.

Richie is penalized by Tony because he is still selling cocaine on his garbage routes, but for Uncle Junior the income from cocaine is his "lifeline". Richie suggests having Tony killed and says he can muster support from other dissatisfied crews. Junior permits him to raise the matter with capo Albert "Ally Boy" Barese, who is not persuaded. Alone, Junior thinks it over: he calculates that Richie, failing to "sell" the plan to Albert, is not respected; he, Junior, is better off with Tony. He tips Tony off, and Tony starts planning a hit on Richie with Silvio.

Richie and Janice spend a quarrelsome evening at home. She tells Richie that Tony does not want his children near him because of what he did to Beansie. Richie expresses disgust at the presumed homosexuality of his son, who is a dancer; Janice contradicts him, and he silences her with a punch to the mouth. She goes out of the room, comes back with a gun, and shoots Richie dead. In a panic, she phones Tony, who finds her crying over the body. He calls Christopher and Furio to dispose of the body. They dismember it with the meat-cutting equipment at Satriale's.

In the morning, Tony encounters Livia, in whose house Richie and Janice were staying, for the first time since her stroke. Tony explains that Richie has left; Livia smiles at a distraught Janice and says she knew it wouldn't last. She laughs when, on his way out, Tony stumbles down the stoop and falls on the front walk. Janice returns to Seattle.

Carmela contrives a meeting with Victor. She says that one day she might be free and, as she leaves, kisses him lightly on the cheek. Victor is greatly relieved when she has gone.

Loading the washing machine, Carmela smells Irina's perfume on Tony's clothes. However, he has had enough of Irina and breaks up with her. In response, Irina attempts suicide with vodka and pills. Tony goes to the hospital and comforts her. He then sends Silvio with a parting gift of $75,000. Irina's cousin, Svetlana Kirilenko, urges her to accept it.
