“Gotham” Season 1 took a break from introducing new villains and made the Penguin (Robin Lord Taylor) a professional gangster. He is officially working his way up the ranks with Maroni (David Zayas), but he doesn’t seem to mind helping out Gordon (Ben McKenzie). Oswald Cobblepot proved that he has many faces in “Gotham” Season 1 episode 4, titled “Arkham.”

Episode 4 picked up right where episode 3 left off with Cobblepot on Gordon’s doorstep. Gordon took him into an alley outside to get away from his girlfriend Barbara (Erin Richards).

“I should’ve killed you,” Gordon said. “I should put a bullet in your head right now.”

The Penguin gave Gordon an option: kill him or trust him. Gordon couldn’t kill him and Cobblepot warned him that a war was starting over Arkham.

Mayor James (Richard Kind) wanted to use Thomas and Martha Wayne’s plans for Arkham. They wanted to build affordable housing and a new mental hospital. Falcone (John Doman) supported this plan. However, Maroni had other plans for the abandoned Gotham district. He wanted to start a waste management facility there and rebuild the old asylum himself.

Sure enough, Falcone and Maroni sent a killer after anyone on the Gotham city council who supported their opposing side—but they sent the same assassin. A man using the name Gladwell (Hakeem Kae-Kazim) stabbed a councilman Ron Jenkins and his aide using a tool that looked like a kaleidoscope because he supported Falcone’s plan. Then he killed councilman Zellers who supported Maroni’s plan. He worked for whoever paid him.

The Penguin seemed like he was trying to keep his head down, but a shooting happened at the restaurant. Cobblepot was hiding in the freezer with one bag of the money. Maroni took this gesture to heart and promoted him to restaurant manager since the old manager was killed in the robbery.

The Penguin tipped Gordon off to another Gotham city council murder. He promised that a politician would be killed, and Gordon realized that Mayor James had a lot of protection around him. He went to the mayor’s house and discovered empty police cars. He tried to get the mayor out but the killer came in while they were trying to run. He even got Gordon’s gun away from him. He chased them through the house and nearly stabbed Gordon in the eye, but Bullock (Donal Logue) saved him at the last minute. They both shot Gladwell dead.

Barbara worried about what Gordon was doing at work with the Gotham City Police Department. She knew he was hiding secrets because Montoya (Victoria Cartagena) tipped her off. She asked about Cobblepot, but Gordon didn’t understand how she knew that name. She revealed that she dated Montoya for a year. Gordon was angry that she hid such an important detail from him.

Barbara later apologized and said that she didn’t want any secrets between them. She asked again about Oswald Cobblepot, and Gordon refused to tell her anything. She decided that she couldn’t stay with him if he wasn’t going to be honest with her. It seems that Gordon and Barbara are breaking up...for now.

Cobblepot wasn’t being very honest either. The Penguin sent the robbers to Maroni's restaurant. They had the money waiting for him in an abandoned apartment, and they even offered to run more jobs for him if the money was this good. He apparently didn’t want to take them up on that offer. He fed them poisoned cannoli and took the money.

Mayor James announced that Arkham would be low income housing (Falcone’s project) and a waste disposal facility (Maroni’s project). The asylum will be remodeled by Maroni -- meaning that Maroni is officially a major player in Gotham.

It appeared that Fish Mooney (Jada Pinkett Smith) was prepared for a change in power. She was auditioning singers for the nightclub. Fish revealed that she wasn’t looking for a girl to work for her—she needed a weapon. Fish had her two singers fight for the spot as her nightclub singer. Liza (Makenzie Leigh) quickly knocked the other girl unconscious and said she was ready to start.

“Gotham” airs Mondays at 8 p.m. EDT on Fox. Why does Fish need a pretty girl to be a weapon? Share your theories in the comments section below!
