Christopher Moltisanti

Season One

Christopher begins the series as Tony's driver and enforcer, and is eager to rise through the ranks in the Mafia. He "makes his bones" by killing Emil Kolar in order to settle a dispute with the Soprano family over the Triborough Towers garbage routes. He initially plans to place the body in a Kolar Bros. dumpster to send a warning, but "Big Pussy" Bonpensiero convinces him to put it elsewhere as it would bring less heat to the crew. The murder haunts Chris' dreams, and he twice has to dig up and move Kolar's corpse.

Chris aids his friend Brendan Filone in hijacking Comley trucks, which are under Junior Soprano's protection. The two are ordered to pay $15,000 in restitution to Junior and leave the trucks alone. Chris and Brendan plan another heist while high on methamphetamine, but Chris backs down at the last minute out of loyalty to Tony. Brendan and two others go through with the heist, which ends in the accidental death of the driver. Chris is reprimanded by Tony for not using his leadership to stop Brendan. Junior, angered that his authority was flouted, stages a mock execution for Chris in the New Jersey Meadowlands. Brendan is shot in the eye by Mikey Palmice.

Christopher later avenges Brendan's death when he and Paulie ambush and murder Mikey out in the woods.

Season Two

Chris is put in charge of the family's pump and dump scam, with Matthew Bevilaqua and Sean Gismonte serving as his subordinates. Eventually, Bevilaqua and Gismonte decide to murder him to gain favor with Richie Aprile. The pair ambushed Chris outside a diner and badly wound him, but Gismonte is killed and Bevilaqua flees the scene. Chris has his spleen removed and goes through a traumatic recovery process with Adriana by his side. Bevilaqua is eventually tracked down and shot to death by Tony and Big Pussy. Chris later tells the crew that during his coma, he had seen himself in either hell or purgatory and warned them that Brendan and Mikey told him that three o'clock would be a significant time in their future.

Following Aprile's death, Tony calls Chris and Furio Giunta to dispose of his body; they use Satriale's bandsaw and processing room to dismember the corpse. At Meadow Soprano's graduation, Tony proposes to let Chris be made.

Season Three

During Chris' initiation ceremony, he notices a crow on the windowsill and takes this as a bad omen. As the family's newest member, he inherits a betting shop from his capo, Paulie Gualtieri and is charged with paying minimum weekly dues to him. There is friction when Chris has difficulty making payments to Paulie, who subsequently humiliates him. However, after the Pine Barrens incident, they agreed to bury the hatchet. Elsewhere, Chris opens the Crazy Horse Nightclub in Long Branch with Furio Giunta as a partner and Adriana as front operator.

Chris is present when Jackie Aprile, Jr. and his friends try to rob a card game run by Eugene Pontecorvo. Chris and acting capo Albert Barese kill Aprile's friend Dino Zerrilli as he tries to escape. Chris, jealous and resentful of Jackie as a rival for Tony's favor, expresses his intent to put a hit on Jackie, which Tony denies. This caused Chris to question Tony's leadership. Eventually, Vito Spatafore carries out a contract killing on Jackie in the Boonton Projects. At Jackie's funeral, Chris is arrested on a gambling charge along with Patsy Parisi and Silvio Dante.

Season Four

To protect himself from prosecution, Tony makes Chris main contact in criminal dealings. He then bonds his nephew to him by having him murder Lt. Det. Barry Haydu, after telling Chris that Haydu had murdered his father. Chris surprises Haydu in his home, interrogates him, and ultimately kills him. He is later made acting capo when Paulie is imprisoned on a gun charge and is awarded a no-show job at the Esplanade construction site. His promotion irks Patsy, who has seniority. The two come to blows over Patsy's continued theft from the construction site, despite orders from Tony. Silvio was actually the guiding force behind Patsy's actions, as he was also jealous of Chris' promotion.

Chris' drug use spirals out of control following his temporary promotion. When Tony calls upon him to dispose of Ralph Cifaretto's body, he realizes that Chris is high. Although they successfully hide the body, Tony decides his nephew needs help. Later, Chris is carjacked by a Latino gang while trying to buy heroin. When Chris physically abuses Adriana, Tony organized an intervention. However, the meeting ends badly when it's revealed that Chris had accidentally killed Adriana's dog by sitting on it when high; Tony, whose beloved race horse being killed in a fire set by Ralph, becomes very angry. He insists Chris go into rehab and assigns Patsy to guard him.

Following Chris' successful rehabilitation, Tony entrusts him with the planned hit on Carmine Lupertazzi; Chris contracts the job out to Credenzo Curtis and Stanley Johnson, who he had known from his period of heroin abuse. When the job is called off and Tony urges him to make sure it can't be traced to them, Chris has Benny Fazio and Peter "Bissell" De La Rosa murder Curtis and Johnson while he waits in his car.

Season Five

Chris and Paulie are put in charge of a cigarette smuggling operation. While Chris is traveling to North Carolina to pick up cigarettes, Tony and Adriana are involved in a car accident. Rumors begin to spread that the crash was caused by Adriana performing oral sex on Tony. Chris finds out, gets drunk, starts a fight with Vito, and pulls a gun on Tony in the Bada Bing. Tony is prepared to kill Chris, but their cousin Tony Blundetto steps in and saves his life. Tony B arranges a meeting with a doctor who treated Tony and Adriana, who explains that both passengers were upright and in their seat belts when it occurred. Chris reconciles with Vito and Tony.

Chris later travels to his uncle Pat Blundetto's farm alongside Tony and Tony B. They help Pat move bodies hidden on the farm as Pat is planning to move away. While there, Chris recalls being bullied by the two Tonys, and they exhibit such behavior by ribbing him over his addiction problems.

Throughout this time, Chris maintains a turbulent and sometimes violent relationship with Adriana. He indulged her aspirations for a career in music by allowing her to produce a demo and later giving her a club to run. They became engaged before he is sent to rehab. However, after he learns that Adriana has reluctantly provided information to the FBI, he turns to Tony rather than accept her plea to join her in witness protection. Tony sends Silvio Dante to meet with Adriana, purportedly to drive to the hospital to visit Chris, but in reality he executes her in the woods. Chris relapses into heroin use and weeps to Tony out of grief for Adriana.

Season Six, Part One

Chris is promoted to capo in the Soprano family, in keeping with Tony's long term plan to raise his nephew through the ranks until he eventually is appointed boss. He uses Chris to organize a sensitive hit on Rusty Millio. Chris initially questions Tony's decision to contract the job out to their friends in Naples, but later decides it was a smart move. He uses his Italian-speaking associate Corky Caporale to communicate with hitmen and provide them with weapons and instructions, while paying him off with heroin. Chris' readiness for the responsibility of leading his own crew is unclear as he is distracted by a potential career in Hollywood, has relapsed into drug use, and displays unresolved feelings over his murdered fiancee.

Chris' crew get involved in a credit card fraud scam; his AA sponsor James "Murmur" Zancone and Benny Fazio take numbers from local businesses and sell them on to associates Ahmed and Muhammad. He wonders about whether these men have links to terrorism. The use of numbers from Nuovo Vesuvio^{[upper-roman 1]} lead to a violent dispute between Benny and Tony's friend Artie Bucco. Tony blamed Chris' trip to Los Angeles for the dispute not being settled quickly.

Chris marries Kelli Lombardo after learning that she is pregnant with his child. He has a belated bachelor party with the Soprano crime family at Nuovo Vesuvio, where "Larry Boy" Barese makes a toast to his future. However, when he later delivers Corky's final payment, including more heroin, he cannot resist when he watches his friend inject the drug. He spends the night at the Feast of St. Elzear festival with a stray dog.

Chris takes a road trip to Pennsylvania with Tony just before the feast. On their way home, they spot some bikers robbing a strip mall and take part of the haul for themselves. This leads to a firefight in which Chris shoots one of the bikers as Tony drives away. Later, the two get drunk on the wine they had stolen, and Chris recalls telling Tony of Adriana's treachery. The two express their love for and loyalty to each other — though when the two later try to recreate their camaraderie sober, it falls flat and ends in an awkward silence. Months later, Chris is back in AA meetings.

Season Six, Part Two

Chris premieres his film Cleaver at a private screening with other Soprano associates, looking to having it distributed nationwide. He also tries to distances himself from the criminal lifestyle and stays away from the Bada Bing. When Tony begins grooming Bobby Bacala for the position Chris once held, it is clear that their relationship has cooled. Given Chris' resentment towards Tony about Adriana's death, and his continued desire to enter the film business, the two continue to drift apart. When he relapses to drinking after yet another confrontation with Paulie, he becomes very angry with the crew and leaves. He later ends up at his "friend" J.T. Dolan's home, looking for someone to talk to. When J.T. foolishly made explicit mention of Chris' membership in the Mafia, and refuses to let Chris talk out his problems that night, Chris shoots him in the head and leaves.

As Tony and Chris drive back from a meeting with Phil Leotardo and the New York crew, Chris – clearly impaired by drugs and alcohol – crashes his Cadillac Escalade. Tony is well enough to climb out of the SUV, but Chris is badly injured and coughing up blood. He pleads for Tony's help, mumbling that he wouldn't pass a drug test and could lose his license. After getting out, Tony sees a tree branch impaling a car seat where Christopher's daughter could have been sitting. He pinches Chris' nostrils shut, causing him to choke to death on his own blood.

Throughout the episode's remainder, Tony displays the proper decorum for the family in mourning yet can barely restrain his relief that he is finally free of the burden Chris has placed upon him for so long – his insubordination, his substance abuse, his reckless behavior, and his complaints. He describes Chris as a "drag" on his emotions, and "a weak, lying drug addict".^[3] In a dream, Tony admits to Dr. Melfi that he murdered Chris, as well as other friends and associates Tony B, Big Pussy, and Ralph. In the series' final episodes, Chris' picture is hung in the pork store in his honor; Paulie is disturbed that the resident cat spends its days staring at the picture.

Clandestine knowledge

Because of his close relationship with Tony Soprano, Christopher is the only one (besides Tony) who knows which bodies were buried at "Uncle Pat" Blundetto's farm and where they were moved after Pat sold the farm, where Tony Blundetto's body was buried after Tony Soprano shot him, and what really happened to Ralph Cifaretto. Chris is also one of the few (along with Furio Giunta) to know Richie Aprile was murdered by Janice Soprano, and (along with Silvio Dante) to know about Tony Soprano's murder of Fabian Petrulio, about the aborted plan to hit New York boss Carmine Lupertazzi, Sr. and about Silvio's murder of Christopher's fiancee, Adriana La Cerva.
