In a separate interview, Farrell teased how The Penguin leads right into The Batman Part II, telling ComicBook, “It conveniently worked that the death at the end of The Batman and the devastation within Gotham opened up a power vacuum that then Oz could try and capitalize on.”

It's all coming together. Whatever happens in this film will further give Penguin a place to grow into. We can see it in detail during a Penguin season 2, and then top off this story with Batman Part III featuring Penguin as the primary antagonist, an antagonist that Batman created.
