The Penguin charts the rise of Oz Cobb, AKA the Penguin, in Gotham's criminal underworld after the death of kingpin Carmine Falcone in The Batman – and he's up against Carmine's own flesh and blood in the form of his daughter Sofia (Cristin Milioti), fresh out of Arkham Asylum.

Some observant fans might have noticed some interesting comic parallels between The Penguin's newest flunky and one tenured Batman villain.

The Penguin Episode 2 properly introduces us to Sofia’s therapist, Dr Julian Rush – and there may be more to him than meets the eye.

The latest example of this is "The Penguin" showrunner Lauren LeFranc downplaying the series' Batman roots. No, this is a serious crime drama, hence why Oz (Colin Farrell) can't actually be called the "Penguin" even if he waddles like one onscreen.
