Plot

In an attempt to get his job back, Gordon seeks to capture Jack Gruber, a deranged electronics genius who has escaped from Arkham Asylum. Meanwhile, Falcone struggles to hold onto his empire after Fish Mooney makes her next move.

Gordon gambles Harvey's badge too, seeking to return on the police force, by daring commissioner Loeb, who needs results in the case of escaped 'electrocutioner' Jack Gruber. The detectives, brilliantly aided by forensic freak Nygma, trace the Arkham asylum patient brains frying creep, who turns out to be a serial killer's manufactured alter-ego, leaving another trail of electrocution victims, on his vindictive mission against disloyal former crime partners. The most prominent is Maroni, so Gordon convinces him to seek protective custody at the precinct, a dangerous trap. Meanwhile only Oswald sees trough Fish's plan to dethrone Falcone by faking his now beloved domestic companion Liza's kidnapping, but he can't warn the don as long as he's caught up in Maroni's terrorized party.—KGF Vissers

Arkham escapees Jack Gruber and his lobotomized pet giant Danzig make their way to a warehouse to retrieve Gruber's stuff.

In the station, they're searching for any history on Gruber. James Gordon interrupts the captain's briefing, but Captain Essen and Harvey Bullock try to hustle him out before the commissioner can arrive and blame Gordon for everything. The commissioner arrives and hauls Gordon and Bullock into his office.

Meanwhile, at the warehouse, after retrieving his machine, Gruber gets to work lobotomizing an employee.

In with the commissioner, Gordon rails against the Arkham experiment and promises he'll bring in Gruber and Danzig, after the commissioner reinstates him. They get 24 hours.

Carmine Falcone listens to a man beg for his life, and even though they're family, he's unmoved.

Later, he offers to set his housekeeper Liza up with a business so she can meet a nice man and get married. She tells him she prefers to stay with him, he makes her feel safe.

At the station, Ed brings Gordon and Bullock news that Jack Gruber is really Jack Bukinsky, and he wanted to be transferred to Arkham. Ed rushes off to follow up on the "riddle" he left for Miss Kringle -- a cupcake with a bullet in it. She found it "menacing and weird and inedible", she is un-charmed.

Bukinsky pulled four successful bank robberies, killing six people. He never named his accomplices.

They get called to the scene of the abandoned Arkham prisoner transport van. They notice Irwin's Electronics nearby. They find an electrocuted employee by the door. The lobotomized employee is mindlessly writing the same thing over and over on the wall like Bart Simpson: "I will not betray my friends."

Liza is grabbed off the street by masked men. She's relieved when she's brought to see Fish Mooney, who tells her she's ready to make her move against Falcone.

At home, Falcone gets a ransom call for Liza.

Back at the station, the newspaper has dubbed Gruber/Bukinsky "The Electrocutioner." Ed suggests Bullock and Gordon wear their department-issued rubber boots, just in case.

Dr. Leslie Thompkins drops by with a voodoo doll. The inmates make them and give them to a pagan sorceress on her wing. Gruber made "Mr. M." They both think it looks like Maroni.

Meanwhile, Oswald Cobblepot gets a call from Falcone's disappearance. He excuses himself from lunch with Maroni. The Irwin Electronics van sits outside. Oswald makes it to the door but is blown back off his feet by an electrified door handle. A light bomb is thrown into the restaurant.

Later, Maroni and most of the other men have survived. Gordon explains to Maroni who's after him and asks to take him into protective custody. Charred Oswald manages to sit up in the back of the ambulance and say he needs to leave for urgent business with Falcone.

Cut to Maroni and a goon carrying Oswald into the station.

Barbara Kean drops by her parents' mansion unannounced, hoping to stay a few days. She tells her prim mother that she's very happy with Gordon.

At the station, Maroni holds court while Gordon waits for Gruber to make his move. Oswald wakes up and tries to leave, but Maroni asks him about his business with Falcone.

Fish calls Falcone, saying she's acting as an intermediary. But he doesn't buy it for a minute, saying she was always the smart one. She tells him to leave town and she'll let him take Liza with him. Liza is prepared to go along with it, saying Falcone's always been good to her. Fish remind her she can never tell him the truth.

At home, Falcone seriously thinks about leaving town, over Victor's objections.

Ed tells Miss Kringle the answer to his riddle: "The cupcake is sweet, the bullet is deadly: a beautiful woman's a dangerous thing." She's touched for half a second, then goes back to being creeped out. Detective Arnold Flass interrupts, bullying Ed away.

Ed hears a power surge as he leaves, then hears Kringle tell Flass: "He is so weird."

Outside, Buckinsky drills into the station walls and hooks up his machine to its steel structure.

Inside, Oswald swears he has no business with Falcone and is about to leave when electricity starts flying through the air. The lights go out and everyone in the station drops.

Inside, Bukinsky is disappointed that everyone is only stunned, not dead. Gordon sneaks up on Bukinsky with a gun, saved by his rubber boots. But Bukinsky uses a weblike machine to latch onto Gordon's gun and super heat it. Danzig attacks Gordon, who somehow gets the upperhand against the giant. Bukinsky accuses Gordon of not caring about the law, just hating to lose.

Bukinsky charges his machine and prepares to lash out at Gordon. Gordon fights back in the simplest way possible: he tosses a cup of water on Bukinsky's circuits and fries them.

Later, Commissioner Loeb holds a splashy press conference and gives Gordon his badge back. Gordon whispers to him: "The next man who tries to take away my shield, one way or another, I'm going to make him eat it."

Gordon announces to Bullock that he's done being careful. Bullock scoffs at the idea that Gordon has been careful so far.

Oswald finally makes it to Falcone's house and relays what he knows: that Liza was planted by Fish from the beginning. Fish found a girl who looked just like Falcone's mother and taught her how to act. Falcone doesn't want to believe it.

Fish calls Falcone to meet in an hour. He arrives alone. Fish wants him to sign papers relinquishing control of the family, but he insists on seeing Liza first.

When Liza is brought out, he asks how long she's known Fish. Liza protests, but Falcone isn't convinced, noting a little bird told him what Fish put Liza up to. He reminds Fish how they used to talk about his mother. Falcone's armed muscle and Victor arrive, drawing on Fish.

Falcone sweetly strokes Liza's face and tells her he's sorry she got mixed up in everything. Then he chokes her to death with his bare hands.

He orders Fish kept alive for the moment. Above all, he's upset she used the memory of his dear mother against him. Falcone calls for Oswald, who relishes having the upper and against Fish.

At the station, Lee Thompkins drops in on Gordon. She feels dumb for coming when he doesn't immediately seem to understand why she's there. But he stops her from leaving and kisses her. They're interrupted by news of a shoot out at Fish's place.
