What's next on Gotham? Fox official website

Gotham Season 1, Episode 6 titled Spirit Of The Goat airs tonight (27 October) and will show James Gordon and Harvey Bullock dealing with a serial killer who wears a goat mask. The episode's official synopsis also suggests that things will get pretty intense for Gordon.

"When a killer begins targeting the first-born of Gotham's elite, Bullock is forced to confront traumatic memories from a nearly identical case he worked in the past. Later, Gordon is confronted by past decisions," reads the synopsis.

In a new trailer (below) for the upcoming episode, owing to this deadly crime wave in Gotham, Alfred Pennyworth urges young Bruce Wayne to leave the city. Wayne refuses to leave and tells his butler that he has to continue his Wayne Enterprises investigation, states a Design & Trend report.

Meanwhile, a quite interesting fan theory suggesting that the most iconic and popular Batman villain – The Joker - has already been revealed on the show, is circulating the web.

Warning: Potential Gotham Spoilers Ahead

Originally posted on Reddit, the theory suggests that the show's Penguin, Oswald Cobblepot, is actually the Joker. Here's how:

"Oswald Cobblepot is supposed to be dead. He knows that with such an unusual name it's bound to get back to Fish Mooney that someone named Oswald Cobblepot is still in Gotham. So he hires a short fat kid to go around telling people his name is Oswald Cobblepot. This kid idolizes the Joker so he does everything he can to be more like him. He dresses like him, he walks like him, he carries an umbrella just like him.

Meanwhile original Cobblepot realizes he has to hide his identity if he's going to continue to operate as a gangster in Gotham and develops the Red Hood identity (one of Joker's origin stories).

This short fat kid with the big long nose becomes the Penguin. The original Cobblepot has an industrial accident later on and becomes the Joker."
