“Folie à Deux” does neither. Taking a cue from the last scene of “Joker” — a psych evaluation where Arthur hears Frank Sinatra’s “That’s Life” in his head and starts to sing along — the film is basically one long drawn-out courtroom drama, interrupted by musical numbers (old standards, most of them sung in Arthur’s head).

One TikToker has taken a deep dive into the film, and thinks that it was Joker rather than Arthur Fleck pulling the strings the whole time. User Society.made.the.joker posted a video, in which she argues that "the Joker is a real persona, and he’s a persona that comes out to protect Arthur."
