This penultimate episode is a masterclass in storytelling, weaving together a complex tapestry of clues, red herrings, and jaw-dropping revelations that will leave fans eager for the final reveal.

The episode kicks off with our trio, Charles, Oliver, and Mabel, hot on the trail of Sazz's mysterious protege, a key to unlocking the truth behind her untimely death. Their initial lead, Glen Stubbins, remains in a coma, leaving them with more questions than answers. A chance encounter with the bartender at Concussions sheds new light on the situation, revealing that Glen was not Sazz's protege but was brought in to replace him after a disastrous performance. The only ones who know the true identity of the protege are Sazz, Glen, and the film's director, the legendary Ron Howard.
Determined to get to the bottom of things, the trio hatches a plan to infiltrate a film set where Ron Howard is working. Disguised as background actors, they manage to sneak onto the set, only to be thwarted by security. Meanwhile, Mabel receives a call that Glen has regained consciousness, prompting her to rush to the hospital. Tragically, before she can arrive, Glen is murdered in his hospital bed, his emergency contact—Sazz—having been called by a mysterious man.
As Mabel grapples with the news of Glen's death, Charles and Oliver find themselves off the set and at Oliver's favorite Chinese restaurant. Their argument about Oliver's bachelor party leads to a heartfelt moment where Oliver asks Charles to be his best man. The tension is cut short by the surprise arrival of Ron Howard, who not only recognizes Oliver but also provides the missing pieces of the puzzle regarding Sazz's protege.
Ron recounts the story of how Sazz's protege, Rex Bailey, was involved in a stunt gone wrong on the set of Project Ronkonkoma. Rex's impatience and recklessness led to an incident that cost him his job and earned him a place on the blacklist. In a twist, it's revealed that Rex Bailey is none other than Marshall, the writer behind the "Only Murders in the Building" movie. The discovery of Ron's burnt boots, matching the footprint at the crime scene, connects Marshall to the murder.
The episode culminates with Mabel's return to her apartment, where Marshall awaits to discuss the script. While fetching a beer, Mabel stumbles upon a script for the "Only Murders" movie, shockingly credited to Sazz. Just as she questions Marshall about this, she receives a text from Charles revealing Marshall as Sazz's protege. The episode ends on this cliffhanger, leaving us with a plethora of questions about Marshall's true intentions and his potential role in Sazz's murder.
