Season 4

Jen's mother, Emma, will be soon going into labor at the hospital while Jonesy and Jude start wheelchair races in the hospital corridors. Caitlin is forced to use a pay phone, which she has a fear of using, rather than her cell phone which she is forbidden to use in the hospital. Meanwhile, Nikki is too afraid of babies to help Jen's mother with the breathing exercises. Jen tries to be excused from work to go see her mother at the hospital, but she ends up getting stuck in many places, from having her shoelace stuck in the escalator to getting put in the slammer at Ron the Rent-a-cop's office, and when Nathan, a new boy Jen likes, helps to free her, they both end up stuck inside one of the mall's elevators.

Jen and Nathan are still in the elevator trying to find a way to get to the hospital in time so Jen can help her mom give birth. Jude unknowingly chats up with a dead body, and Jonesy becomes a clown to entertain the kids at the hospital, while Nikki is in love with newborn babies in the hospital's nursery, but she accidentally puts two babies in the wrong cribs when she put them back. She then goes to Jonesy for advice on how to switch the babies back, eventually leading into Nikki telling Jonesy that she loves him. She then disguises herself as a nurse in an attempt to switch the babies back and prevent a couple from mistakenly taking the wrong baby home. In the end Jude takes a picture of everyone gathered around the new baby, Emma.

Jen's mom asks Jen if she can take care of baby Emma, until Coach Halder calls Jen to report to work at the Penalty Box. Jen then assigns Jonesy to take care of baby Emma on her behalf while she works. Jonesy gets bored at home, so he takes Emma to the mall, but baby Emma kept crying so he gives her to Nikki to look after. Nikki, meanwhile, experiences weird dreams about being in a relationship with Darth, so she passes the baby to Caitlin. Baby Emma then vomits all over Caitlin, who then gives her to Wyatt at Burger McFlipster's. Needing to get away from his new co-worker Wayne, Wyatt leaves with the baby and heads to the ice rink to give her to Jonesy, but Jude puts her on the Zamboni, which then drives off into the mall after Jude accidentally disengages the parking brake. Ron the Rent-a-cop gets baby Emma and gives her back to Jen, who then finds out her parents are getting home

Olympic athlete Travis Gibson visits the mall to meet Jen, but Jen won't spend time with him because of the time Travis threw a rock right at her forehead back in grade 2 and gave her a nasty scar. Caitlin decides to give up boys for good and go into art after her new flame Spencer dumps her. Jonesy can't seem to remember where he got hired for a new job. Jude, who is now unemployed after getting fired from the ice rink, looks to find ways to make some money, including fishing coins out of the mall fountain and making a bet with an elderly man at a classic game shop. A picture of Camp Wawanakawa from Total Drama Island can be seen at the art show. In the end, Jen ends up dating Travis.

Nikki quits her job at the Khaki Barn and gets a new job at a cooking store. But she soon finds out that cooking isn't in her blood, due to the fact that she made pumpkin muffins and accidentally put laxatives in them causing her to get fired and get her old job back. Meanwhile, Wyatt starts dating Lacey, a girl who has way too much in common with him and it starts to creep Wyatt out. Also, Jude gets a copy of the game "Rock Maniac" (a direct parody of the real-life Rock Band and Guitar Hero game series) in his store and the gang start their own "Battle of the Rock Maniac Bands" contest.

Teen singer Kylie Smylie visits the mall to sign some autographs for her fans and perform a concert as well. Caitlin, who wrote a contest essay to get a chance to meet Kylie, is declared the winner. Serena broke up with Chad and wants to have another shot at a relationship with Wyatt, but he refuses and instead accepts Kylie (leaving Serena saddened in the process), as she has interest in him. Unfortunately, Kylie's father/manager, an ex-pro wrestler called Sgt. Beef, won't let Kylie date until she's at least 21. Jonesy scores a job as Kylie's bodyguard and Jen tries everything she can just to see her. Nikki and Jude have problems with the Escalator Girls and need to find a way to get back at them.

Jude finds out that he has a lucky zit, while Wyatt becomes depressed because he can't manage to get a girlfriend after his last date disaster. Jonesy gives him "The List," which is a list of girls he had previously dated and short details about them, which leads to Nikki and him having a fight about how long have they dated and Nikki declaring that they are going to have a break from each other until Jonesy can figure out why and how he's dating her. Near the end, Jonesy finally declares Nikki as "The One," mostly what Caitlin calls every boy that she dates. Meanwhile at Albatross & Finch, Caitlin notices she had lost her credit card and she sets out to find it, with help from Jen, by tracing purchases made on the card after its disappearance.

After Jonesy gets a job in a mini golf course, he starts charging couples to make out in the pitch black UFO, which ends up with Caitlin and Wyatt accidentally kissing when each thinks the other to be their respective dream dates. Meanwhile, Jude's 10-year-old cousin, Jade, comes to the mall. She is crushing on Jonesy, buying him presents (new shoes, sunglasses) which makes Nikki convinced that she is shoplifting, but while trying to catch Jade in the act, Ron catches Nikki and, convinced (as usual) that Nikki is up to no good while overlooking the real culprit in Jade, throws Nikki in the mall security lockup. When Jonesy comes to bail her out, Jade convinces him to accept her as his new girlfriend in exchange for getting the keys from her. Meanwhile, Travis Gibson comes back to the Galleria to Jen's delight, but he makes

Caitlin tries to find a way to fix the blender after one of her giant earrings dropped into it, but both she and Jen develop crushes on the repairman who comes to fix the blender. The girls turn it into a competition to see who can get a date with him first, and with Nikki as the referee, Jen secretly gets her to spy on Caitlin to see if she tries resorting to her usual tricks (like eyelash-fluttering) to get the repairman. However the repair man turns out not to be so handy and they resort to not dating him. The girls fix the blender just in time and Caitlin does not get fired. Jonesy, Jude and Wyatt wait in a long line for a blockbuster alien movie, but they keep getting out of line and losing their spots, until they make a deal with Wayne to keep their spots in the lineup – but then, Wayne goes back on his word and causes the guys to all lose their spots again through various dirty tricks. When Nikki stops by, Jude asks her to empty what

Wyatt, Caitlin, Jen, and Jude are loveless at the time so they get mad when they see Jonesy and Nikki flirting with each other right in front of them. Nikki suggested sarcastically to join a speed dating session, and Jonesy decided he wanted to host it because he got kicked from his last job, and needed money. So, Nikki and Jonesy start a speed dating service for Jen, Caitlin, Jude and Wyatt to help find their special someones. Jen received a new method of being mean and unattainable for getting guys from Jonesy while Nicki seconded Caitlin's idea to be nice and respectful to the guys. Therefore, they made it a competition; Caitlin used her nice and sweet act and Jen used her too-good-for-you methods on the double date they had to go to with the two Asian twins they chose. Both of them are nervous, and Jonesy and Nikki at once interfered with the foursome because of arguing. What made it worse was that Caitlin

A Sadie Hawkins dance comes to the mall where the girls ask the guys out. While Jude and Wyatt struggle to get chosen, Caitlin and Jen try to overcome the pressure of asking the guys. Nikki becomes friends with a new Khaki Barn employee Jean, but spends so much time with her, she forgets to ask Jonesy to the dance, and Caitlin needs to find a way out of date with Wayne after he mistakenly thinks she asked him out.

Nikki's father is accepted for a job up in Iqaluit, and Nikki doesn't want to go, so Jonesy gets Caitlin to tell Mr. Wong that his interview was moved to Grind Me at the mall, and Jonesy pretends to be Mr. Wong at the real interview, when he tries to do everything he can to make him not get the job. It doesn't work, however, because he gets the job anyway. So Nikki has to convince her parents to let her stay but she has to find a place to stay first. Jen's mom said she could stay with them for a semester but Nikki's parents don't want her living under the same roof as her boyfriend, so Nikki and Jonesy pretend to break up so she can stay with them. But Nikki finds out that living with Jen is too hard. Meanwhile, Jude loses his house keys while his parents are away so he temporarily lives in the mall, where he is repeatedly hounded by Ron the Rent-a-cop.

When Nikki's friends do a going-away party at Grind Me for her, Nikki's parents said they would stay as her father would keep his old job, but Nikki objects and admits that it should be time for her to "grow up" and that she should finally make some self-sacrifice after everything that her parents have done for her. So she agrees to move up North to Iqaluit so her father can get the job. Upon departing, Nikki attempts to call Jonesy on the cell phone just to tell him that she doesn't want to break up with him, and Jonesy wishes the same. The gang says good bye to Nikki and tell her they'll talk to her soon, as she bids them one final farewell. It finishes with Jonesy saying "Maybe everything will be okay after all..." The episode, and the series ends, with the camera zooming out to a wide shot of the mall food court as all the supporting characters in the show are seen walking through.
