"I have a welcome back speech to deliver. And thanks to my sister, I'm late."
The relationship between sisters Maya Matlin and Katie Matlin was introduced when Maya entered Degrassi Community School. Both sisters worry about one another, despite their age gap. Katie is seen to be often overprotective of Maya, and is quick to give advice if needed based on her own personal experience.
In Underneath It All, Maya is first seen in Marisol's car along with older sister, Katie. Katie gives Maya advice and tells her to try to have fun in Degrassi, though Maya does not seem enthused since Maya wanted to go to an arts school. While waiting for Katie to pick her up, Maya is on Zig's Facerange page and closes it when Katie notices. Katie says Zig is cute and asks Maya if she has a crush. Maya explains how he asked her to The Dot but Tori and Tristan say that he's the devil and warned her to stay away from him. Katie begins to tell Maya that before she started dating Drew people said he only cared about sex (which she quickly changes to the word "sports"), which ended up not being true. Katie tells her not to listen to the gossip and give Zig a chance. After accidentally getting Tori and Zig back together, Maya expresses to Katie that she never realized how much she liked Zig until he was gone. Katie shows her sympathy to Maya. Maya asks "Is high school always this complicated?" to which Katie says "The least." Then, Fiona barges into the room and Katie tells Maya to go and wait at Marisol's car as she deals with the drama of Fiona.
In Can't Tell Me Nothing (1), Maya asks Katie if she's okay suspecting purging when she catches her going through the fridge. Katie tells her she's fine. Maya believes her and leaves.In Can't Tell Me Nothing (2), Maya catches Katie sneaking pills from their mom’s bottles and promises to not tell on Katie. She just needs to make it through her try out and then she’ll stop taking the pills. Maya is even more worried about Katie once she gets detention and tells her it's a bad idea to run on her leg. Maya greets Katie along with her mom and takes the rest of the pills so Katie can't.
In Hollaback Girl (1), Maya enters the kitchen during the night to come across a soaked Katie (when Bianca sprayed water on her) with Bianca informing her that her older sister is high on pills.

In In The Cold, Cold Night (2), Maya arrives with Katie's trumpet at Frostival, saying that it's her musical challenge. When she epically fails on the trumpet during the band's performance, Ms. Oh, Tori, and Tristan, as well as Maya, all find it amusing.
In Waterfalls (1), Maya and Campbell Saunders want to go to the mall, so she asks Katie for a ride at the garden. Katie asks what it's for and realizes it's a boy. When Maya says that it's Cam, Katie says no and that hockey players are bad news in which Maya replies that just because Drew dumped her doesn't mean all jocks are bad. Katie eventually accepts but says that she will chaperone to Maya's dismay.
At the mall, the three of them are seen getting out of a movie while Katie berates Cam with questions. Maya tells him he doesn't have to answer and points out "Drew and Bianca kissing" to distract Katie while they run. The two turn the corner and head into a photo booth where they talk about their siblings and Cam's home life while taking pictures. Maya tries to kiss him and he pulls back, saying they should probably find Katie.
In Waterfalls (2), after school, Maya is in her room playing the cello when Cam walks in and tells her Katie let him in.
In Doll Parts (1), Katie walks into the bathroom while Maya is getting her makeover and laughs at her.In Doll Parts (2), Katie gives Maya a headband for her pageant dress, and tells Maya that she thinks that she could win the pageant with her supporting her. Katie asks what Maya's talent is, and Maya says she was thinking of playing the guitar with Zig as her accompanist on lead guitar. Katie questions if this would make Tori jealous, but Maya says that all is fair in "love and beauty pageants", to which Katie agrees, and they high five. Katie helps Maya get ready for the pageant, and hugs her before she goes on stage, wishing her luck. Later, Katie catches Maya kissing Zig, and lectures her over it. She tells Maya that she is easy, while Maya claims that it was Zig who kissed her, but Katie tells her it takes two people to "kiss tango". Katie says that Tori is Maya's best friend and asks how she could turn on her after two days in a pageant, but Maya defends her behavior by saying Tori was being mean. Katie asks her little sister if she really wants to be a boyfriend stealer, and tells her that boys are shallow. Maya confesses that Zig makes her feel good about herself, but Katie insinuates that he's only paying attention to her because he is superficial and only cared for her improved appearance for the pageant. Katie says that Zig is not good enough for Maya because he is the kind of guy who kisses other girl's girlfriends, and pleads to Maya to not let him come between her and Tori.
In Tonight, Tonight, Maya yells at Katie to open the door since she is studying with Campbell and Tori. Later at school, Katie gives Maya advice about her situation with Zig and Campbell. She tells her that Zig is doing the right thing by breaking up with Tori because he is being honest, and that the kiss with Zig was in the past, so she shouldn't worry about it with Campbell.
In Degrassi: Las Vegas, Maya tells Katie and Jake to get a room when her and Campbell walk in on them kissing. Katie teases her, asking if she wants them gone so that her and her boyfriend could hold hands alone. Maya gives Katie the letter from Stanford, and when Katie finds out she has been accepted, her and Maya begin jumping in excitement.
In Bitter Sweet Symphony (1), Katie announces to Maya that "a bouquet with legs" got delivered to her, which is really Campbell holding flowers for Maya. Katie has Maya if she is okay before she leaves. Maya tells Campbell that she'd like him to stay if it was okay with Katie since she is in charge. After some time, Katie returns and tells Campbell that he needs to leave because it is late. Maya asks Katie if Campbell could sleep over on the couch, but Katie rejects the idea. Maya tells her that she owes her since she always covered for Katie when she would previously sleep over at Jake's. Katie begrudgingly agrees, but states it is a one-time thing only and Campbell has to leave when their parents get home. The next morning, Katie rushes in to wake Maya up since they overslept and will be late for school.
In Bitter Sweet Symphony (2), Katie advises Maya to forget about Campbell since he is acting weird, and the two head to Principal Simpson 's office upon the urging of Madame Jean-Aux. Mr. Simpson reveals to the girls that Campbell is dead after committing suicide, and Katie is shocked. She promises to not leave Maya's side, and she asks Maya what she wants to do, to which Maya said she wants to practice for her music audition. Katie leaves Maya alone and lets her practice. She later announces to Maya that their parents are coming back home early, and tells Maya that she can't audition today. Marisol enters the room and tells Maya and Katie that they are holding a candlelight vigil for Campbell, and asks Maya if she would like to speak. Katie insists that it would be a good idea since the way Maya is acting is scaring her, and tells Maya she can't do her audition and the candlelight vigil.
While Maya is trying to figure out what to write for Campbell's vigil, Katie tells her to write what is in her heart. She leaves to get Maya some water. Later, before the vigil, Katie asks Maya how she is doing and tells her that the police found Hoot. She promises to come get her before the ceremony starts, which she promptly does. Katie listens to Maya's speech about how Campbell doesn't deserve the vigil, and she defends Campbell, saying that he was sick when Maya says he should have fought harder. When Maya walks out of the ceremony, Katie calls after her. The next day, Maya chooses to go to school, and Katie tells her that Maya knows where to find her if she needs her.

She yells that she isn't the one who needs help, but Katie is.

Katie is furious when seeing the two in their position and throws Harry out of the house.
Once alone, Katie scolds Maya for her reckless and wild behavior lately. When she finds out Maya hooked up with Harry at the Torres house, she makes a "Oh, great..." comment, bringing Maya to reference to the time Katie herself lost her virginity there. Her reference in front of their mother makes Katie even more furious. When Katie says how scary it is that Maya is acting and tells her she can't replace Cam, it triggers Maya's breakdown about his death. She then laments on how she hates Cam because he broke up with her by committing suicide, how she feels like she won't ever be happy again and the fact that he never said goodbye to her. Maya then breaks down in tears, sobbing, and Katie hugs her in comfort.

Maya gets home 20 minutes late and her mom says she can't go to Paris. Maya complains that it isn't fair and says that she hates her. Maya walks into the kitchen and Katie says that was harsh. Maya talks about that Katie never had a curfew like Maya but Katie says that she had sports and actually wanted to go home in the evening. Maya asks her if she thinks that she shouldn't be going to Paris either and Katie says that they should talk in the morning. Maya then takes her things and heads to Tristan's house.
She sleeps there overnight and the next day, Katie calls her and asks her where she isn't but she doesn't say. Later, Maya comes back home and apologizes to her mother, and then she and Katie talk.
