Only Murders in the Building Season 2: Who killed Bunny?

Fighting to clear their names, the trio spent Only Murders in the Building Season 2 going through various red herrings on who’d want Bunny dead. Suspicion soon fell on Cinda Canning (Tina Fey), a rival true-crime podcaster who’d bragged about solving the murder of Becky Butler. But Cinda’s assistant Poppy (Adina Verson) told Mabel she was really Becky, hinting Cinda was basing her career on a lie. 

The trio held a “killer reveal” party where Mabel accused her girlfriend Alice (Cara Delevingne) of killing Bunny in a rage. Alice seemed to prove it by stabbing Charles to death. Cinda praised Mabel for her work, with an outraged Poppy slipping up by revealing a detail only the killer would know.

Charles sat right up, revealing the whole thing was faked to trick Poppy into confessing she killed Bunny as she and a detective lover were planning their own podcast “solving” the crime. 

The season ended by jumping a year in the future as Charles was starring in Oliver’s new Broadway show, only for star Ben Glenroy (Paul Rudd) to drop dead on opening night.
