Gotham Fall Finale Preview: Barbara Reveals To Nygma Who Killed Isabella

The bromance between The Riddler and The Penguin is about to come crashing down.

In last week’s episode of Gotham, Edward Nygma wrongly suspected Butch of being responsible for Isbella’s deadly car crash, so he abducted and tortured Butch and Tabitha. In effort to prevent Tabitha’s hand from getting lopped off, Butch admitted to killing Isabella, but since he couldn’t recall the manner of her death correctly, it finally dawned on Riddler that Butch wasn’t really to blame.

Meanwhile, while that was all going on, Barbara searched high and low for Butch and Tabitha, and along the way, she discovered that The Peguin has romantic feelings for Nygma. By the end of the episode, she puts two and two together and realizes that Penguin was jealous of Isabella and had her killed.

In this clip from Monday’s fall finale, Barbara confronts Nygma, telling him with a fake cough that Penguin is the true killer and uses a riddle to explain the mayor’s motive.

As the virus begins to spread in Gotham, the laboratory that is developing a cure is compromised. Mario and Gordon face off before the wedding, Selina meets an unexpected face and Barbara comes to Nygma with information about Isabella.
