‘Only Murders in the Building’ Season 2 Ending Explained: Who Was the Killer?

Hulu’s comedy hit Only Murders in the Building season two managed to up the stakes and ended with a shocking twist that kept viewers guessing the whole way through.

The series stars Steve Martin as Charles, Martin Short as Oliver, and Selena Gomez as Mabel; three residents of the Arconia hotel on the Upper West Side with a penchant for solving murders and sharing their stories on their popular podcast. The series has earned an impressive 17 Emmys and its premiere was the most-watched original comedy for the streamer.

New familiar suspects

In season two, the gang aren’t just solving a new murder, they’re implicated in the crime. Bunny Folger (Jayne Houdyshell), the Arconia board president, has been stabbed by a knitting needle and Mabel (nicknamed “Bloody Mabel”) is the first suspect, seen leaving the scene of the crime with the needle and blood all over her. This puts her and her compatriots in the crosshairs of the Williams (Da’Vine Joy Randolph) and Detective Kreps (Michael Rapaport) who’re looking to solve this case.

As the trio attempt to exonerate themselves throughout the season, Charles’ daughter Lucy (Zoe Margaret Colletti) comes to visit, Oliver worries if he and his son are biologically, and Mabel has a new love interest Alice (Cara Delevingne), a rebellious artist. The season is also filled with guest stars including Amy Schumer, Jane Lynch, and Shirley MacLaine who thicken the plot.

Cinda & Poppy

In episode nine, “Sparring Partners,” it’s revealed that Cinda Canning (Tina Fey), the rival true-crime podcast host of Only Murders in the Building, could be the killer. Her assistant Poppy (Adina Verson) has a conversation with Charles, Oliver, and Mabel where she reveals her real Becky Butler, the missing girl from Cinda’s popular podcast All is Not OK in Oklahoma. Poppy/Becky was once a mayor’s aide who grew tired of her life.

She changed her hair, put on glasses, and sought out Cinda to sell her the story. The podcast blew up and gave Cinda more notoriety, but none of that is shared with Poppy. Cinda and Poppy attempt to come up with other stories that don’t quite work and Cinda decides to set up the Only Murders in the Building podcasters to take care of the competition once and for all.
