Season 4 arc of Gotham: Fool for You. Episode 1-"You've Gotta be Joking Me."

An anti-villain's origin story long in the making finally reveals itself.

Rated M (Warning, this will contain some sexuality, some triggering content for abuse victims, and violence...because Gotham. Enough said.)

Note: I'm treating this like a probable Gotham episode, where we see what happens next in the plot.
