There’s still plenty of season for another big name to pop into the game though, so perhaps fans shouldn’t assume someone like Penguin (who will apparently appear again in The Batman) or even a character like Mad Mod won’t be rearing their evil heads eventually across the pond.
That conclusion was drawn after having viewed the first four of Pennyworth Season 1, which will last for ten episodes, so it’s implied loose Batman connections (aside from the obvious Alfred Pennyworth and Thomas Wayne) won’t be springing up anytime soon.
