Fan CastingJoker: The Arthur Fleck Story

Description of Rose Wilson (Timejump/Guest Appearance):

At another point in the series, Arthur, who has made a bit of a name for himself in Wayne Enterprises, is attending the wedding of Bruce Wayne and his girlfriend, Rose. He smiles gently, but then presses a button on a device in his hand, which causes several pipe bombs under the floor boards to detonate. Once the bombs go off, Arthur immediately gets up from his seat, fires a gunshot in the direction of the bride and the groom with a deagle, then runs out of the courtyard in the Wayne Enterprises building. Bruce survived, while Rose did not, leaving this as the final element that transforms Bruce into the Batman at last.
