The Penguin has spent its first three episodes teasing Sofia’s escapades as the infamous Hangman serial killer, an adaptation of the comics canon “codename” she earned in Jeph Loeb and Tim Sale’s Batman: Dark Victory by committing a string of calling-card murders.

But the majority of the episode actually takes place ten years prior to The Penguin's present-day events, instead focusing on a younger Sofia as she's framed for murder by her father, crime lord Carmine Falcone (played by John Turturro in The Batman and now played by Mark Strong in flashbacks).

It feels counterintuitive, but it’s quite a joy knowing that you don't have to hunt through The Batman spin-off looking for Easter eggs. Here's a great example: The Penguin episode 4 took viewers to Arkham Asylum and didn’t show us the Joker.
