Zendaya | K.C. Undercover | Season 3

 

"Coopers on the Run"

K.C., Marisa and the rest of the Coopers flee to a safe house in Rio de Janeiro after Zane and his men target them. After two weeks in the safe house—a run-down apartment—K.C., Ernie and Marisa go into the city to contact the Organization. While in the city, Ernie meets Zoe, a young woman from Kansas who likes him. However, K.C. is suspicious of Zoe and ends their conversation as the Coopers are not to speak to anyone because of the possibility that Zane could be tracking them. K.C. contacts the Organization and learns that Zane is unaware of their whereabouts. K.C. then signs up the family for a mission to capture Passaro Grande, a local smuggler of exotic birds. After capturing Grande, Craig, Kira and Judy take him to the local authorities while K.C., Ernie and Marisa return to the safe house. A strong enemy agent named Sheena, who frequently talks to herself, breaks into the safe house and reveals that she was sent by Zane to kill them. After fighting K.C. and Ernie, Zoe breaks in and knocks out Sheena. Zoe reveals that she is an agent for the Organization who was assigned to protect the family. The group gets into a vehicle to head to a safe location, but K.C. must take a detour through the jungle after learning that Sheena is following them. The next day, Sheena locates the group and incapacitates Ernie, Marisa and Zoe with a small device that electrocutes them. K.C. and Sheena prepare to battle.

"Welcome to the Jungle"

During battle, K.C. tosses a Brazilian jumping spider on Sheena to paralyze her. Ernie, Marisa and Zoe regain consciousness and discover that K.C. has also been paralyzed by the spider. They leave Sheena behind and carry K.C. through the jungle. Zoe eventually makes an antidote for K.C. out of jungle vegetation and snake saliva. Meanwhile, Marisa is upset that today is school picture day and she is not there to have her picture taken. Marisa wanted a yearbook picture to remember the fact that she became a high school senior despite her poor grades. After wandering through the jungle, Craig, Kira and Judy find Sheena, who claims to be Zoe. They then find K.C. and the others. K.C. and Zoe apprehend Sheena, and Marisa and the Coopers later board a helicopter. During the flight, Zane reveals himself to be the pilot. Zane destroys the helicopter controls and parachutes out while the helicopter spirals out of control toward the ocean.

"Out of the Water and into the Fire"

K.C. manages to land the helicopter safely in the ocean, and Marisa and the Coopers are rescued by a nearby military ship. The captain apprehends them after discovering that Judy is a robot, as he does not believe that the Coopers are spies and he has never heard of the Organization. Marisa and the Coopers escape from their cell after using Judy's skeleton key. The Coopers return to Organization headquarters, where they discover a memorial service being held for them. The Coopers decide to keep their survival a secret to increase their chances of capturing Zane; they recruit Kira's parents, Othello and Gayle, so they can work together. Disguising her voice as Brett, Judy arranges to meet Zane at a laser tag facility, where K.C. and her family ambush him. After battling with real laser guns, Zane is apprehended, and K.C. declares that they no longer have to worry about The Other Side, unaware that a new enemy Organization known as The Alternate has been formed.

"Web of Lies"

K.C. is upset to learn that she has received the same SAT score as Marisa: 1060. K.C. later learns that Beverly had Craig change her SAT result because she received a perfect score. Less than one percent of the population receives a perfect score; leaving the original score intact would draw unnecessary attention to K.C., putting her spy career at risk. K.C. disagrees with Beverly's decision as it will prevent her from being accepted into certain colleges. Beverly tells K.C. that the Organization wants her to remain a spy rather than go to college. K.C. drives to New York to retake her SAT test, while Ernie and Zoe team up for a mission to stop smugglers who are working in a party supplies warehouse. After completing the mission, Ernie asks Zoe to be his girlfriend, but she tells him that she has been assigned to a four-year mission in Antarctica. Ernie agrees to wait for Zoe until she concludes her mission. Meanwhile, Marisa wants K.C. to talk to the Organization about letting her become a spy. Marisa is insulted when K.C. tells her that she is not intelligent enough to be a spy. K.C. later tells Marisa that it would be better if she attended college rather than become a spy. Marisa, who does not want to attend college, becomes further upset at K.C. and decides to temporarily end their friendship. Two months later, K.C. learns that she has received a perfect SAT score.

"Teen Drama"

Marisa, who is still upset at K.C. for not allowing her to join the Organization, befriends a student named Brady, who says that he is part of the Organization. Brady tells Marisa that the Organization has been impressed with her for a while as she helped to capture the leader of The Other Side. Brady recruits Marisa as a spy for the Organization. Meanwhile, K.C. misses spending time with Marisa. Ernie invites his fellow Model UN member, Monique, to the Cooper house to spend time with her, but he becomes upset at K.C. for befriending Monique and disrupting his plan to be with her. K.C. realizes that spending time with Monique is not the same as being with Marisa. Brady assigns Marisa to befriend K.C., who he says could be providing intelligence to The Other Side. Marisa befriends K.C. again so she can learn whether she is working with The Other Side.

"K.C. Under Construction"

K.C. is assigned to go undercover as a construction worker at a tall unfinished building, allowing her to spy on a nearby tower where a group of renegade spies are believed to be meeting so they can discuss weapons. K.C.'s male co-workers at the construction site mock her for being a female. K.C. meets a female construction worker, Crystal, who tells K.C. that the men will eventually ignore her. K.C. later learns that the renegade spy group is working on sonic brain imploders, capable of melting people's brains. When Brady has Marisa gain knowledge about K.C.'s current mission, he warns his group that K.C. is spying on them and that she must be killed. A man is sent to the construction site to plant a brain imploder device. After a fight, K.C. takes down the man, but he says he does not know how to diffuse the imploder. Crystal has K.C. put the imploder into cement mix, which prevents it from detonating. Meanwhile, Judy gets in trouble at school after using mature logic to question a student's belief in the tooth fairy. Ernie is tasked with teaching Judy to behave like a normal child, to help maintain her cover as a spy robot.

"The Storm Maker"

Ernie and Marisa mock K.C., believing that she does not have a date for their final high school homecoming. On the night of the homecoming, K.C. goes on a mission to retrieve a weather-altering device known as the Storm Maker, which the remaining members of The Other Side plan to use to create man-made weather disasters. K.C. retrieves the device and hides it in her school locker, where she plans to keep it while she attends the homecoming. K.C. has Howard, a gadget inventor for the Organization, pose as her date at homecoming, telling him that it is actually practice so he can become a field agent. Marisa attends homecoming with Brady, while Ernie goes with Monique. Brady learns about the Storm Maker through Marisa after having her casually question K.C. about her latest mission. Brady, who is working for The Alternate, steals the device and places it in his locker, then deletes security footage of his theft before K.C. and Ernie can learn who took the device. Meanwhile, Craig and Judy attend a father-daughter dance at her school.

"Keep on Truckin' "

K.C. and Craig discover that the Storm Maker device cannot be powered without a rare chemical known as Dilithium. They go undercover as workers at a truck stop restaurant so they can obtain the Dilithium from a truck that is delivering it. Meanwhile, Ernie gives Judy an emotion upgrade to increase her mental sensitivity, to help her maintain her cover as a real child. At school, Ernie overhears Brady during a phone conversation and discovers that he is an enemy agent. Brady uses memory spray to erase Ernie's recent memory. Marisa visits the house to ask Ernie questions regarding K.C.'s latest mission. Ernie then overhears Marisa talking to Brady on a cellular phone, and learns that she is a spy. Marisa erases his recent memories with memory spray. At the truck stop, the driver of the Dilithium truck walks inside for lunch, allowing K.C. to obtain the chemicals. Brady, wearing a ski mask, takes the Dilithium and hijacks the truck. K.C. attempts to take control of the truck, and scratches part of Brady's face through the mask opening, before falling off the truck. Later, K.C. meets Marisa and Brady at a restaurant, and notices the scratch marks on his face. Although he says the marks came from a cat, K.C. realizes that Brady was the truck hijacker.

"Unmasking the Enemy"

K.C. suspects that Brady has been spying on her through a necklace that he gave Marisa, who is unaware of Brady's Storm Maker theft. K.C. believes the necklace is bugged, so she creates a plan to trick and catch Brady. K.C. tells Marisa, who is wearing the necklace, that the Organization has created a device called the Rain Coat, capable of stopping the Storm Maker. K.C. also says that she will be dropping off the plans for the device—which is actually fictitious— in an alley later that night, with the hope that Brady will arrive there to steal them. A masked man from The Alternate arrives to intercept the plans, but he is knocked out by K.C., who realizes that the man is not Brady. Three additional masked men arrive, including Brady, but they are forced away when Marisa arrives and threatens them with a laser gun. Meanwhile, Kira is about to enjoy a day off when Lori, an agent of the Organization, drops off her baby at the Coopers' house so she can go on a last-minute mission. Kira then puts Judy in charge of watching the baby, claiming that she has to go on a last-minute mission. Kira actually gets a massage and has her nails done, while Judy is unable to stop the baby from crying.

"The Truth Will Set You Free"

Agent Johnson puts the Coopers in charge of collecting information on Brady. K.C. arranges a job interview for Marisa to become a junior agent-in-training for the Organization, which leads Marisa to question Brady, who had already told her that she was a junior agent. After being questioned, Brady eventually reveals to Marisa that he is a member of The Alternate. Brady also reveals that he has hours of audio footage in which Marisa states that K.C. may have become a rogue agent and agrees to work with him to take her down. Brady blackmails Marisa to continue spying on K.C., or else he will release the audio footage and get her imprisoned for treason against the United States. Marisa confesses to K.C. that she has been spying for Brady, and K.C. discovers that Marisa's necklace was never bugged. When unusual weather begins occurring around the world, the Coopers realize that the Storm Maker has been activated, so they instruct Marisa to gain information from Brady about the device. When Marisa fails, K.C. goes in disguise as Marisa and confronts Brady, who kidnaps and takes her to The Alternate's headquarters, as she planned. Meanwhile, Ernie wants to drive by Monique's house in his father's 1969 classic muscle car, but he crashes it before getting out of the driveway, scraping away the paint on one of the doors. Judy makes the situation worse by repainting the door a different color and then removing the paint entirely. Ernie and Judy blame the damage on The Alternate, but Craig does not believe them.

"Stormy Weather"

At The Alternate's headquarters, K.C. comes out of disguise and escapes from a room where she had been locked up. K.C. frees an imprisoned scientist named Gwen, who leads her through the building in search of the Storm Maker, but Gwen later reveals she is part of The Alternate. Brady, Gwen, and Alternate member Reid plan to use the Storm Maker to have a massive storm hit the Capitol Building during the State of the Union address. Craig and Kira drive to the Capitol to warn people, but they encounter heavy rain and hail. Marisa enters The Alternate's headquarters to help K.C., and they rush to the rooftop to destroy the Storm Maker's transmitter. After a brawl with Brady, K.C. destroys the transmitter with a laser gun. Brady escapes by parachuting off the rooftop, and Marisa decides that she does not want to interview to become a spy because of the hard work required by the job.

"Deleted!"

Judy's memory is almost full, which requires her to visit the Organization to have her video footage downloaded. The Coopers realize that Judy has recorded everything they have done, including things that could get them excluded from the Organization again. The family decides to delete Judy's incriminating videos, including footage showing that Marisa knows about the family being spies. After reminiscing through old footage, Craig deletes several videos, including important footage from their recent circus mission. When the family discovers that the circus footage cannot be recovered, they worry about how Agent Johnson will react to them tampering with evidence. Ernie suggests reenacting the circus mission in their house and filming it to cover for the deletion of the real footage, which leads the family to reminisce through old videos about his previous bad ideas. The family also watches other old videos, until Agent Johnson arrives at the house to pick up Judy. The family hides Judy and convinces Johnson that she has already left to visit the Organization for the memory download. Afterwards, Judy expresses sorrow that her videos will need to be downloaded and removed, as they serve as her memories. Ernie devises a solution to back up Judy's video footage to a separate hard drive so they can be reinstalled onto Judy after she downloads them for the Organization.

"Second Chances"

After a dangerous mission in which she thought she was going to die, K.C. realizes that she still has feelings for Darien, and Marisa encourages her to tell him how she feels. K.C. wants to hang out with Darien but he tells her that he has a new girlfriend named Bianca and K.C. lies and says that she has a boyfriend and the two agree to go on a double date with each other. K.C. has to find a guy to assist her on the date so she asks Howard to pose as Trey Appleton Jr. and the date becomes awkward. K.C. learns that Bianca is actually nice so K.C. and Marisa plan to set Bianca up with Ernie. K.C. gives Ernie a bottle of confidence serum. Meanwhile, Petey wants Judy to be his assistant in his magic act, which she reluctantly agrees to after being forced by Kira. However, Petey says that her bad attitude will ruin his chance of winning so he decides to get a new assistant, which makes Judy jealous. The next day, Judy wants to be Petey's assistant again and the new one is afraid of being sawed in half. At the Olive Pit, K.C. learns that Bianca is cheating on Darien with Howard and she goes to tell him, but Darien tells K.C. that Bianca is his cousin. Darien tells K.C. that he lied to her because he was afraid of being hurt by K.C. again. K.C. wants to fix things between the two of them, but Darien wants to be able to take things slow so him and K.C. agree to be just friends.

"Revenge of the Van People"

Agent Johnson sends K.C. to Switzerland so she can attend an international conference for young espionage agents. Meanwhile, Johnson puts Ernie in charge of training a trio of agents named Jin, Lecia, and Amelie, with assistance from Howard. Ernie is disappointed to learn that the trio are "van people," the term used for agents who operate from within a van. Ernie is jealous of K.C. and upset because he believes that the Organization does not have faith in him. Johnson informs the five agents of a website, Buzziebuzz, that is using clickbait quizzes to create psychological profiles on young people. Johnson instructs the agents to observe the website's headquarters from within a van and then report their findings. The agents discover that Brady is inside the headquarters, and that the website is a front for The Alternate, which is planning to brainwash the site's teenaged web visitors. Ernie decides that the team will go against Johnson's initial orders and apprehend Brady. Jin, Lecia, and Amelie are unsure of their ability to complete such a mission, but Ernie inspires confidence in them. In disguise, Ernie, Howard and Lecia infiltrate the headquarters, while Jin and Amelie monitor the mission from the van. Jin, an architectural engineer, guides them through the building with a schematic. Upon locating the mainframe room, Lecia hacks into the computer system, allowing Amelie to remotely install a virus to corrupt the website. The team then captures Brady. Johnson becomes upset at Ernie and tells him that Brady had been working undercover after being convinced by the Organization to work as a double agent.

"The Gammy Files"

Craig's father, Earl, visits the family and brings along his new girlfriend, Betty. Craig is pleasantly surprised to see how cheerful his father is towards him now that he has a girlfriend. K.C. becomes suspicious of Betty, believing that she may actually be Margaret Turner, a woman who stole important documents from the Organization in 1977, compromising agents around the world, before disappearing from a hotel. Craig is reluctant to believe K.C.'s theory because he does not want to disrupt his father's new relationship, fearing that such an action would result in Earl returning to his critical behavior. In a storage facility for information related to cold cases, K.C., Ernie and Judy retrieve Margaret's old hairbrush, which had been left behind at the hotel. After obtaining a sample of Betty's DNA and comparing it with the hair on Margaret's brush, K.C. learns that there is a 99-percent match between the two. However, she learns that Betty has a twin sister named Midge, an alternate name for Margaret. K.C. and Judy travel to Margaret's hideaway on a remote island off of Puget Sound, where they apprehend her.

To cheer K.C. up, Marisa eventually asks her out to the prom, which K.C. accepts.

"Take Me Out"

K.C. and Darien decide to go on a date to a baseball game, where they are featured on the stadium's kiss cam. However, they have an awkward kiss because Darien was unaware that K.C. had a nacho chip in her mouth. Afterwards, K.C. goes to the stadium bathroom, where Regina Honey captures her. Honey reveals that when she saw K.C. on the kiss cam, she decided to capture her as revenge after K.C. got her put in prison for two years. At Honey's apartment, while K.C. is handcuffed, Honey reveals that she did not plan ahead on what to do next with K.C. When K.C. mentions how she is upset about disrupting her relationship with Darien again, Honey becomes interested and asks K.C. what she means. K.C. tells her how she previously had to end her relationship with Darien because of spy work, which causes Honey to reminisce about a boyfriend named Joey Damico, who she dated while they were teenagers. The relationship ended after Honey became a criminal, which Joey disliked. Honey, upset about her old relationship, decides to let K.C. go so she can be with Darien, but she is too late as the baseball game is over. Later, Darien believes that he made K.C. uncomfortable by trying to kiss her at the game, and the two decide to just be friends. K.C. then gives Damico the address to Honey's apartment, where they reunite. Meanwhile, Ernie helps Judy improve her creative writing after she receives an "F" in school. To help her, they act out various improv scenes.

"Twin It to Win It"

After visiting the Lincoln Memorial, K.C. and a boy named Byron agree to go on a date the following night. Afterwards, K.C. is briefed about a man named Henry Parker who donated $5 million to American University, which is renaming its library in his honor. Parker has been receiving threats, so K.C. is to go undercover as the solo drum player in the renaming ceremony honoring Parker, allowing her to be close enough to protect him. K.C. is given a special pair of drum sticks that allow her to play the drums like an expert. The next day at the university, K.C. competes with another drummer, Elliot, for the solo drummer position, which she wins by demonstrating her drumming skills. Before the renaming ceremony, K.C. meets Barney Feffer, a university security guard who is initially suspicious of her because there is no record of Cassandra Bailey, the alias that she is using for the mission. K.C. convinces Barney that she is an undercover police officer. K.C., unaware that Byron is attending the ceremony, tells him that she is cancelling their date to be with her sick grandmother, using the excuse to complete her mission. During the ceremony, K.C. apprehends Barney after realizing he is the culprit who wants to harm Parker. Barney explains that he and Parker were roommates at the university 35 years earlier, and he wants revenge on Parker for taking the top bunk bed in their dormitory. Byron then encounters K.C. at the university and questions why she is not with her grandmother. Meanwhile, Ernie helps Marisa write a college essay for the Fashion Institute of Technology. Afterwards, they share several unexpected kisses despite not having romantic feelings for each other. Marisa agrees with Ernie's theory that she was overly passionate about the school and that her passion led to the kisses.

"Cassandra Undercover"

At the university, K.C. tells Byron that she is actually K.C.'s identical cousin, Cassandra. Byron does not believe K.C. and decides to visit her house. K.C. runs home to change into a different outfit and pose as herself ahead of Byron's arrival. Byron still does not believe that K.C. has an identical cousin, so she agrees to have dinner with him and Cassandra on the following night to prove it. Marisa inadvertently helps K.C. remember that Bernice, who is currently a prisoner at the Organization's headquarters, has an identical appearance to K.C. Bernice, now temporarily released from prison, agrees to pose as Cassandra as long as K.C. promises her a new face through plastic surgery. At The Olive Pit restaurant, Bernice runs ahead of K.C. so she can meet Byron while posing as K.C., who is now forced to masquerade as Cassandra. Later in the meal, Bernice goes to the bathroom and, after a brawl with K.C., escapes through a window. K.C., still posing as Cassandra, tells Byron that K.C. had to leave, and he decides to end his relationship with her. K.C. has Marisa wear a disguise to pose as Bernice, to prevent the Organization from realizing that Bernice is gone. Meanwhile, Craig is tired of Ernie complaining about his lack of comfort on missions. Believing that Ernie is spoiled and needs to toughen up, Craig sends him to live in the backyard for a day.

The Organization learns that enemy agents are posing as ordinary people in the Washington, D.C. area, where a covert weapons distribution center is being operated and is distributing laser guns. The Organization hopes to locate the distribution center before The Alternate does. Meanwhile, Marisa is upset that she has not been nominated in the school yearbook for any senior superlatives, especially the most fashionable. Marisa begins wearing outlandish outfits to school to convince the students, including yearbook editor Amy Bishop, that she is the most fashionable student. The Coopers locate the weapons distribution center, operating from within a house in their neighborhood. They locate the man and woman who operate the distribution center and then knock them unconscious during a brawl that damages much of the living room. When Amy arrives at the house, the Coopers realize that the man and woman are her parents. Craig and Kira remain unsure if Amy is involved with her parents as an enemy spy, despite K.C.'s belief that she is not. Amy is memory sprayed so she will have no recollection of the Coopers being spies who knocked out her parents. The agents are unable to locate a distribution list, which would help the Organization eliminate enemy spy networks. The Coopers have the living room restored and the parents memory sprayed, then K.C. is sent to befriend Amy in hopes of locating the distribution list.

"Domino 2: Barbecued"

K.C. attends rigorous dance classes with Amy, and is surprised at how physically fit Amy is, leading her to suspect that she may be a spy. Later, K.C. becomes close friends with Amy, and Marisa becomes upset that K.C. has not been able to spend time with her lately. When Amy invites K.C. to her house, K.C. discovers a laptop that is protected by a password. The Coopers invite Amy and her parents, Mitch and Danielle, to their house for a barbecue, during which Ernie infiltrates the Bishops' house and attempts to learn what is on the laptop. At the barbecue, Amy tells K.C. how nervous she is about going to college soon, leading K.C. to believe that she is simply a regular teenager and not a spy. Kira starts a game between the two families to learn more about each other, with the Bishops unaware that Ernie is listening for possible clues that might unlock the laptop. Marisa, still upset at K.C., arrives at the barbecue uninvited and disrupts the game, which makes Amy's parents uncomfortable. They and Amy suddenly leave the barbecue and return home. Because of difficulty in contacting Ernie, he is unable to escape the house before the Bishops arrive.

"Domino 3: Buggin' Out"

K.C. creates a diversion that allows Ernie to escape the Bishops' house, while Kira learns through hidden cameras that Danielle put audio bugs in the Cooper house. Danielle and Mitch are also heard discussing their boss, an individual known as The Mask. The Coopers keep the audio bugs in place to avoid raising suspicion, and they have Judy use her vocal impersonation ability to pose as the family. Brady devises an idea for K.C. to enter the Bishops' house and switch their laptop with a duplicate that was developed by the Organization. Upon entering their password into the duplicate, the Bishops' files will become visible to the Organization, while the duplicate will mirror the original laptop and its contents to avoid suspicion. Ernie gains access to the Bishops' laptop, but is unable to locate the distribution list. Agent Johnson plans to have Amy's parents apprehended on the following morning and force them to reveal the list. K.C. wants to take Amy somewhere so she does not witness her parents being arrested, but Johnson rejects the idea because it could appear suspicious. Mitch and Danielle, concerned about the Coopers possibly being spies, want to leave the city, but their idea is rejected by Amy, who is revealed to be an enemy spy working with them.

Amy escapes after a brawl, which leaves Marisa covered in food. Brady drives Marisa to New York City for her college interview, while K.C. and Ernie track down Amy. Despite her dirty outfit, Marisa is accepted into the Fashion Institute of Technology, and after sharing the news with Brady, they realize they have romantic feelings for each other. Meanwhile, K.C. and Ernie have tracked down Amy to a lighthouse.

After a brawl, Amy is left dangling atop the lighthouse. She claims she is not The Mask and that it is someone closely associated with K.C. Before Amy can reveal The Mask's identity, she falls into the ocean and escapes, leaving behind a flash drive containing the weapons distribution list. At home, K.C. cannot decide whether she should remain a spy or attend Stanford University. When K.C. learns that Marisa and Brady are a couple, she declines to continue talking with Marisa about her missions, as K.C. does not trust Brady. Agent Johnson is informed of the list, and because of its sensitivity, he instructs that it not be shared with anyone, including Agent Beverly, who is the new head of the Organization. Marisa breaks up with Brady, believing he may not be trustworthy. With the weapons distribution list, the Coopers invite the specified crime bosses to a VIP party ahead of a basketball game. The criminals are then knocked out with gas and apprehended. Beverly declares an end to the spy war, but The Mask sends an anonymous message to the Organization, thanking K.C. for apprehending his competition, allowing him to take over their operations. Brady tells Marisa he will quit being a spy to be with her, but when he overhears that Johnson is The Mask and has reprogrammed Judy to eliminate the Coopers, he is injured by Johnson and sent to a hospital unconscious. Johnson frames Brady by telling the Coopers that he was The Mask. Ernie restores Judy after she tries to kill K.C., but she cannot recall who reprogrammed her.
