"That storyline, I thought, was heartbreaking," said Taylor. "To have those characters come back this season would be extremely exciting."

Taylor and his co-stars Cory Michael Smith (Ed Nygma) and Sean Pertwee (Alfred Pennyworth) also spoke about the end-game for Gotham - including how the final ever episodes might play out.

Spoilers: It involves Batman.

Gotham: The Complete Second Season is out on DVD and Blu-ray from August 1.
