The Arconia’s West Side Is A Whole New World

Even thoughOnly Murders in the Buildinghas taken place in the Arconia from the beginning, season 4 emphasizes that the story has only really focused on the east side of the building, which is where Charles, Oliver, and Mabel have lived. It is only now thatthe west side is being truly explored, with its residents being colloquially referred to as Westies. They are revealed to be an eclectic bunch, who have developed their own unique culture and community on their side of the building.

One disadvantage that the Westies have is they are unable to open their windows because they have been painted shut.

This includes a card game called Oh Hell, which they teach Oliver and Mabel how to play, along with going into the bathroom to carve off a piece of the ham hanging in the shower.

The Plot Thickens Around Sazz’s Death

The Westies have already brought some quality humor to the series and further expanded the Arconia, but their true importance is linked to the death of Charles' longtime friend and stuntperson, Sazz Pataki (Jane Lynch).
