What is the name of the episode where Tony Soprano kills Christopher Moltisanti?

Tony Soprano kills Christopher Moltisanti in “Kennedy and Heidi,” the 18th episode of The Sopranos’ sixth season. It first aired on May 13, 2007.

Tony and Christopher are driving home after a meeting when Christopher, impaired by his drug addiction, loses control of the vehicle. The car crashes down an embankment. Tony escapes with relatively minor injuries, while Christopher is badly hurt and struggling to breathe. After noticing the crushed child seat in the back, Tony decides not to call for help and suffocates Christopher by pinching his nose shut.

The death is especially significant because Christopher is Tony’s nephew, protégé, and longtime criminal associate. Tony had repeatedly defended him despite his heroin addiction, relapses, unreliability, and dangerous behavior. After the crash, however, Tony sees him as a liability rather than someone worth saving.

The episode’s title refers to two teenage girls who drive past the crash without stopping. Christopher’s death is sometimes described simply as a fatal car accident, but the episode makes clear that Tony deliberately finishes killing him. Tony later feels relief rather than genuine grief, reinforcing the moral collapse at the center of the scene.
