Great reaction, guys. Aboyt the last name Cobb, I think the most likely reason it got shortened because Cobblepot is an aristocratic last name in the comics. I think Cobb more accurately reflects his working class upbringing and Street-savvy
It could still be Cobblepot, idk if we got confirmed it ISN'T. Either way I don't mind it either, Riddler isn't Edward Nygma. In fact he was using like 3 aliases I think.
