We Finally Know Who Is Behind Each of the Clown Masks on American Horror Story: Cult

In the episode one grocery store scene, Trifaccia clown seems like he's in charge, a feeling supported by the on-camera murder of Serena Belinda (Emma Roberts) in episode four, "11/9." In that attack, Trifaccia clown definitely seems to be running the show, just like Kai outside of the clown costumes. In the fifth episode, the Trifaccia clown takes off its mask, revealing that it is indeed Kai.
