On this week’s iZombie, Liv becomes her old self after eating the brain of a murdered, ambitious student. Meanwhile, Major becomes the subject of an investigation.
Major wakes up on the couch. Ravi asks him if he’s the Chaos Killer. Major tells him he’s been freezing zombies in hopes that Ravi will find a cure. He fills him in on Vaughn’s threat. Ravi says they should tell Liv. Major says she’d do something to get herself killed.
Liv breaks into Mr. Boss’s office demanding to see Drake. His thug attacks her, but she wins.
Don E lies and tells Blaine that he’s the owner of the funeral parlor, not Blaine. He tells Blaine to just sell the product upstairs and not worry about downstairs business.
A couple of students find a dead body in the campus pool.
Liv tells Ravi that Drake is undercover Vice and she beat up one of Mr. Boss’ goons. He tells her that Major is a zombie again. He gave Major the brain of an optimist to keep him happy.
At the crime scene, Ravi tells Clive that the victim, Bailey, was strangled. Bailey’s friend tells Liv that frat house Brody did it. They were competing for student president. She found out Brody had someone take his SATs for him. If he didn’t drop out of the race, Bailey would get him expelled. She was hyper-competitive.
Ravi finds Adderall in Bailey’s system. Liv thinks Bailey’s brains will keep her focused on work and less worried about Drake.
Clive and Liv interview Brody. He says Bailey wouldn’t have gone through with her threat because he caught her selling Adderall. He and his frat brother were out for a walk when Bailey was killed.
Vaughn shows the Super Max commercial to Rita. She’s locked up as a zombie. He says he’ll find a cure after the Super Max launch.
Liv goes to Vice Detective Benedetto and tells him she saw Drake get in a car with Mr. Boss. Clive asks Benedetto about Bailey’s arrest. He says he gave her a scare and let her loose. Liv has a vision of Benedetto telling Bailey he’d ruin her life.
Clive found a charge on Bailey’s meal card the night she died. He and Liv go to the snack bar to investigate. The snack bar worker, Steve, says Brody used her card that night.
Clive tells Liv her efficiency is scaring him. She tells him about Drake. He says a couple times, when he went undercover, no one heard from him for weeks.
A student tells Clive that Detective Benedetto killed Bailey. He says Benedetto makes arrested teens work as confidential informants. They have to buy drugs six times while wearing a wire to wipe their records. He didn’t know six drug dealers, but he knew Bailey took Adderall. He offered her money for a couple of pills. She got arrested for it. Benedetto told this student not to talk unless he wanted to end up like Bailey.
Clive confronts Benedetto, but he says he’s not worried about Adderall. He wants to stop the flow of Lucky U. He tells them that they thought he had a lead, but the guy started babbling about working for zombies.
Peyton goes to Blaine and reams him out for using the DA’s office to make himself the city’s new drug kingpin. He doesn’t remember Mr. Boss.
Blaine finds workers in the basement bundling drugs. Don E yells at him for coming down.
Benedetto goes to Liv’s apartment and tells her that Bailey was working for him, but he needs the program kept quiet. She tells him what Steve said but says he was mistaken. Brody’s alibi checks out.
Bozzio gives Clive an FBI application. She says he’s underappreciated at the precinct and she won’t be there forever. After the Chaos Killer case is solved, she’s going back to Virginia. Blaine comes in looking for the morgue. He doesn’t remember Clive or Bozzio.
Clive asks Ravi why Blaine comes to him for examinations. Ravi says he thinks he’s the only doctor that Blaine remembers. Clive says he’s faking and dangerous.
Blaine asks Ravi what he’s done to inspire negativity. Ravi tells him his whole criminal history. Ravi then asks him who’s delivering brains to the city’s zombies. Blaine says his boss is handling that.
Ravi tells Major that the new cure gave Blaine amnesia, but the memory loss might be a fluke. Major says he’d rather die than forget everyone he loves. He suggests turning Vaughn into a zombie and giving him the cure. If Vaughn doesn’t lose his memory, they know Blaine is faking. If he does lose his memory, Vaughn becomes a harmless shell of himself.
Liv has a vision of a dealer telling Bailey that she can get massive amounts of Lucky U from Steve. She tells Clive about Benedetto’s visit to her apartment. Clive suggests Steve found the wire when he patted Bailey down and then used it to strangle her.
Chief is at Steve’s apartment. Steve sends him to the kitchen when there’s a knock on the door. Benedetto busts in and threatens to beat the information out of him. He tells Steve that the money he stole from Bailey was marked bills. Chief knocks Benedetto unconscious and kills Steve.
Benedetto tells Clive that Steve was a CI that helped him make so many Utopium busts that he realized he was trying to get rid of the competition for Lucky U. Clive tells Benedetto that he’s going to report his using unregistered CIs to Internal Affairs.
Bozzio finds Clive’s filled out FBI application. A woman asks to speak to the head of the Chaos Killer case. She’s from the pet groomers where Major brought Minor. She recognized the dog in the paper and gives Bozzio Major’s name.
Major is at Vaughn’s office with the cure in his bag. Vaughn’s assistant whispers something to him and Vaughn calls off their workout. As Major is leaving, the FBI arrests him and he goes into zombie mode.
