The Fox Batman prequel returned this week, and with it came a new location and new characters.

The second half of Season 1 of "Gotham" takes place in Arkham Asylum, where main character James Gordon, who is portrayed by Ben McKenzie, has been reassigned.

In Episode 11, which is titled "Rogue's Gallery," Gordon is investigating attacks on Arkham Asylum prisoners, and he finds out that Nurse Dorothy Duncan is really an inmate. But he is still tied to the police station and his partner, Harvey Bullock. Gordon asks Harvey for help with an investigation.

Harvey tries to hatch a scheme so that Gordon can get his job on the police force back.

According to Spoilers Guide, Episode 12 is called "What the Little Bird Told Him."

The official synopsis reads: "In an attempt to get his job back, Gordon seeks to capture Jack Gruber (guest star Christopher Heyerdahl), a deranged electrical genius who escapes Arkham Asylum. Meanwhile, Falcone struggles to hold onto his empire after Fish Mooney makes her next move in the all new 'What The Little Bird Told Him' episode of GOTHAM airing Monday, Jan. 19 (8:00-9:00 PM ET/PT) on FOX."

In the promo, Gordon is seen talking to the other officers. He explains that he knows how Jack thinks and that he knows what he will do next, which means that the rest of the force needs him.

At the end of the 30-second clip, Gordon is seen pointing his gun at Jack, who turns around with a smile on his face. The two are in the police station.

Fish also makes an appearance in the video, and she says that she is going to make her move on Falcone.

The Penguin makes an even briefer appearance in the video.

"Fish, you sly devil," he said before laughing.
