Only Murders in the Buildingseason 4 is keeping viewers on the edge of their seats following a shocking reveal about the killer. The season focuses onthe murder surrounding Sazz Pataki, Charles Brazzos' stunt double. However, episode 6 had one of the biggest moments of the season, when the main trio, Charles (Steve Martin), Oliver (Martin Short), and Mabel (Selena Gomez),realized they were being stalked by the killer.
In a recent interview withTheWrap, showrunner John Hoffman explained the significance of this twist and how it will affect the characters moving forward. Healluded to some fan theories being answered in the upcoming episodes. Read his full response below:

We’ve known that there are connective tissues that extend from the beginning of our show for our three main characters up to now, that there are unanswered questions and plot holes. The reflection back on the trio themselves and what they they’ve started with this podcast and what potential dangers are still around in that building and who has been onto them from the beginning causes them to look back at the film of their own lives here in these last four seasons.
We have fans that have many, many theories, and I know there’s some questions that have not been answered that they want answers to. I think some of those questions may be answered this season in a really satisfying way. Not all of them, but I think the audience will be pleased in many ways by getting some solid answers to some difficult questions.
