One day at The Bing, Tracee expressed her thanks to Tony by giving him some homemade bread for advising her to take her sick son to the doctor, but Tony firmly reminded her that he was a superior like Silvio. This did not stop Tracee from seeking his advice on whether to have an abortion or to keep the baby. Tony gave his advice, although reluctantly, that taking her age and situation into account and with Ralph as the father, it would be best to get an abortion. Later, Tracee missed work, and Silvio hunted her down to find her waiting on Ralph hand and foot. As Silvio forced her into his car, he slapped her and threatened Tracee, telling her she is forced to be a dancer until the debt for her braces is repaid. Rather than confront Silvio about abusing Tracee, Ralph watched from the window laughing uncontrollably. The following night, Tracee met Ralph at the Bada Bing VIP lounge, where she insulted him in front of the other associates and capos. Ralph followed her out to the deserted parking lot, where he teased her into thinking he would actually marry and support her. He then abruptly changed his tone and gleefully made snide remarks that her daughter would end up as a "cocksucking slob" just like her. Outraged, Tracee slapped him and insulted his masculinity, which led to Ralph brutally beating her to death. When Tony found out about this, he assaulted Ralph, violating a well-established Mafia code according to which made men were never to strike one another. Tony attempted to justify his actions by stating that Ralph "disrespected the Bing". When asked about his opinion on the incident by Tony, Silvio said that Tony would only have been able to physically retaliate if it had involved a mistress or a blood relative, and since Tracee was neither Ralph had a legitimate complaint against Tony and was owed an apology. Although Tony is disappointed that he cannot retaliate against Ralph, Silvio is also angry at Tracee's murder and says some punishment is justified, and tells Tony that Ralph is now banned from the Bada Bing.
Tracee's murder would have some effect on Tony's psyche, as he reports on the depression to Dr. Melfi, but lies that a teenage boy employed with Barone Sanitation died in an accident as Carmela was in joint therapy with him. During Thanksgiving dinner, when Tony sees Meadow in the kitchen, he has a momentary vision of Tracee, arguably as Meadow and Tracee were not that far apart in age. Tony apologizes for the recent rifts between them, and Meadow is more receptive, considering her recent breakup with Noah.
Some time later when Tony kills Ralph in "Whoever Did This" he wakes up in the Bing the morning after the murder and sees a picture of a smiling Tracee on a mirror - the implication being he got some sort of revenge for her murder, albeit for different reasons at the time.
