Nygma really must've loved Isabella for him to go all bonkers about her death. If he's behaving this way now, what is he going to be like when he finds out Penguin was really the one behind it all?
Gordon and Bullock examine the evidence of the murder at Lee and Mario's engagement party on Gotham. "Mad City: The Executioner" is the ninth episode of the show's third season.
Penguin needs to start focusing on other things besides Nygma. He's got a city to run, and he needs to do something about Butch. Taking care of Tabitha would be nice too.
