To this point, it felt like The Penguin was just about a sleazy underboss attempting to make his way to the top, but perhaps with a heart of gold. That's changed.

The following review contains spoilers for the fourth episode of The Penguin, “Cent’anni.”

The Penguin Episode 4 “Cent’anni” takes us back ten years in the past, when Sofia was less an unhinged mob boss and more the Audrey Hepburn of Gotham. As the society front of the Falcone family, it’s young Sofia’s job to host charity luncheons and attend major galas. It’s Oz Cobb’s ( Colin Farrell) job to drive her to these events.

When Sofia Falcone (Cristin Milioti, in the role of a lifetime) told her therapist, Dr Rush, that she was off for a fresh start, this wasn’t quite what he had in mind. But after being framed by her family for the murder of seven women – and sent to Arkham State Hospital where she was tortured and abused for 10 years – it’s no wonder Sofia wanted revenge on those who set her up.

Sofia Falcone has been dealing with being known as "The Hangman" in The Penguin Season 1. But who is the real killer?

The Penguin breaks its rhythm in episode 4 with an outing that’s almost entirely a flashback. With Sofia Falcone at its center, we finally find out her links to the Hangman, how she ended up in Arkham,
