OMITB Season 4 Ending Explained: Who Killed Lester? What is season 5 about?

The fourth season Only murders in the building solved the mystery of Sazz’s murder and revealed whose death is the main topic of season 5.

The Hulu series premiered in August 2021 and follows Mabel (Selena Gomez), Oliwier (Marcin Krótki) and Charles (Steve Martin) How solve mysterious deaths which take place in their apartment building in New York. Season 1 dealt with the death of Tim Kono (Julian Cihi), the second season saw the unveiling of Bunny Folger (Jayne Houdyshell) murderer, and in season 3 the main mystery was the death of Ben Glenroy (Paul Rudd).

Season 4 began with Charles, Oliver and Mabel initially unaware that Charles’ body double, Sazz (Jane Lynch), was shot in his apartment. Although the trio eventually realized what had happened, they spent most of the season trying to determine whether Sazz was the target… or whether the bullet was intended for Charles.

In the penultimate episode, it is revealed that Marshall P. Pope (Jin Ha) wasn’t just the person writing the script for the film based on the lives of Charles, Oliver and Mabel. Marshall was Sazz’s prodigy until a stunt gone wrong forced Sazz to replace Marshall with Glen Stubbins (Rudd). As an act of revenge, Marshall killed Glen after shooting Sazz — and credit for the script.

On Tuesday, October 29, during the season finale, Marshall confirmed that he acted alone and killed Sazz because she was going to tell Charles that she wrote the script. Marshall held Mabel – and therefore Oliver and Charles – hostage once they found out, but Jan (AmyRyan) saved the day by shooting him from Charles’ apartment.

The trio thought they were lucky when Oliver’s wedding went off without a hitch. But the next morning they found Lester (Teddy Coluca) bleeding to death in the fountain in Arconia.

When Bev got him a movie deal, Marshall confessed to Sazz, but she wouldn’t let him take the credit. This caused him to kill Sazz to keep the secret and later Glen because he recognized him.
