I'm the secret baby! Bex is my mother! And my mother is my grandmother and Amber... is wearing my bracelet!
Andi Mack is the lead, main protagonist and title character of Andi Mack. She is turning 13 at the beginning of the series when her world turns upside down after discovering a huge secret. She navigates the world with her best friends, Buffy and Cyrus. Andi Mack is portrayed by Peyton Elizabeth Lee.
Andi is a creative and artistic person. She makes art, mostly bracelets, from pretty much anything, including scarfs that Bex used to send to her. Andi sometimes comes off as awkward especially in boy-crush situations. Andi is curious and inquisitive and always trying to learn more. Andi is comfortable in her own skin and sometimes overly trustworthy and naïve, although she's not afraid to confront people including her parents for lying to her. She seems to be very intelligent as well because Bex states that Andi is so much smarter than her and Celia in Shhh! and in the season 2 episode I Wanna Hold Your Wristband, Jonah says Andi is very smart.
Andi can also be very controlling at points in the show. Andi tries to force the relationship between Bex and Bowie even getting mad at Bex when she doesn’t want to get married with Bowie. Andi isn't that polite as it seems to her relatives. From the beginning she does everything to pick up a boy who is not single. He even invites this boy to a party and is offended that he took his girlfriend. She also can't admit to her wrong doings when Amber (the girl whose boyfriend she seduced) confronted her. When she finds out that her best friend Cyrus also has feelings for Jonah, she kisses him in front of Cyrus to tease him. She can also be selfish when she don't get what she wants like in Buffy in a Bottle when she gets mad at Bex because she didn't listen to her because she das busy in her project (that's important to her).
Andi Mack was born by a teen mom, Bex but Bex abandoned her sorrowfully after a fight with her mother. Bex's parents, Ham and Celia took care of Andi as their own child. They never told her that she wasn't their real daughter. They told Andi that Bex was her older sister. Bex would come home every few years in the middle of travelling and she would bring Andi cool gifts from all over the world. All this time Andi adored Bex as her cool, fun older sister. We don't know what exactly happened with Bex and Andi in her childhood.
On Andi's 13th birthday, Bex comes back home, and told Andi and her parents that she was finally ready to settle down and get her life together. After an emotional catching up, Andi still felt like Bex doesn't really get her. Bex admitted that she had made a lot of mistakes since Andi was born and showed Andi a picture of her and baby Andi in hospital bed after birth. She revealed that she is not Andi's sister. She's her mother. This changed everything in Andi's world and now she has to adjust into accepting the fact that her sister is actually her mother. Along the way, Andi learns that sometimes the unexpected is what makes life great.
Andi was raised in a loving yet overprotective home. Now, with Bex’s encouragement, she begins to step outside her comfort zone, particularly when it comes to approaching the most intriguing guy at Jefferson Middle School — Jonah Beck, whom she quickly realizes is dating a high school girl, Amber. Andi proves that her greatest strengths may be how she accepts life's unpredictability with optimism. She also finds solace by tapping into her creativity in her backyard hideaway, the Andi Shack.
Since finding out the secret, things have only been harder for Andi. In addition to trying to adjust to the new status and figure out who her dad is, Andi has also been struggling through the intense tension between Bex and Celia. On one hand, Celia is too strict and overprotective and doesn't want to let go of Andi; while on the other hand, Bex is too care-free and doesn't act like a mother. This puts Andi in a tough position as she is often forced to choose which one of them to follow. It becomes evident in Shhh! when Bex encourages Andi to watch a horror movie against Celia's will. This causes Andi to get detention the following day for sleeping in class.
It gets worse in Dancing in the Dark when Cyrus's mom sends an email blast revealing Andi and Bex's secret to everyone. When Ham takes Celia out of town for a getaway, Bex encourages Andi to throw a dance party. The dance party get ruined by Amber when she humiliates Bex and Andi and Andi's absent dad. Both Andi and Bex get in trouble with Celia and Celia even stops talking to them. This makes Andi realize that Bex might be a bad influence on her, as she tells Cyrus in It's Not About You. She realizes that she needs boundaries and wishes that Bex could act more like a mother. Therefore, she starts avoiding Bex by hiding from her. However, when she finds out that Buffy has been spending more time with Bex, she gets jealous and tries to make it up with both of them.
Andi faces a big dilemma in She Said, She Said after catching Amber cheating on Jonah Beck with another boy. She worries that telling Jonah will get him brokenhearted but at the same time she doesn't want anyone treating Jonah the way Amber did. She finally tells Jonah and when she gets a text from Jonah Beck's phone, she runs through the hallways knocking everything on her way to get to Jonah's phone. She is disappointed to find that the text was from Amber to prove to Jonah that Andi is in love with Jonah. Andi refuses to confirm that she likes Jonah. She storms off and is disappointed that Jonah doesn't believe her. Jonah tries to apologize but she forces him to leave. She tells Buffy and Cyrus that she wishes she could move away or die but Buffy suggests faking that she's sick. The trio goes to great lengths to help Andi get "sick" but Bex shocks them when she offers to write her a note so that she doesn't have to go to school.
While Bex and Celia are fighting about whether Andi should go to school, there's a knock on the door. It's Bowie Quinn. Bex introduces Andi and Bowie to each other, revealing that Bowie is Andi's father. Finally. Andi learns more about Bowie in Dad Influence. Bowie asks to hang out with Andi but Celia wants her to go to school. Andi goes to school and is excited to find out that Jonah and Amber broke up. Jonah Beck wants to talk to her but Bowie shows up and shows that they have permission to go hang out. Andi spends the day with her dad and gets to know him better. He films her as they try different adventures and share their feelings about getting to know each other. She realizes that he cares about environment just like her and that he is chill and unpredictable and wild. He even takes her to play bongos after "listening" to the universe. At the same time, Andi is concerned about missing her friends as well as trying to figure out what Jonah Beck wanted to ask her. She says goodbye to Bowie but thanks him for the adventure. At school, she's disappointed to learn that Jonah and Amber are back together. Later at home she asks Bex why she broke up with Bowie and Bex says it's something to do with him being unpredictable.
Andi is shocked to find Bowie in Andi Shack leading to privacy concerns in Terms of Embarrassment. At first Andi is glad that Bowie is staying with them but then she starts feeling embarrassed by him. He spends so much time around her, filming her. He even goes to Andi and Jonah's Space Otters Frisbee team practices and introduces himself to all of Andi's friends. But things get worse when Andi finds him on her laptop. This is where Andi keeps all her private stuff and where she looks at pictures of Jonah Beck. So, she feels her privacy violated and gets mad at Bowie, asking him to leave her alone. When Bowie leaves, she realizes that he was saving the videos he recorded for her to see. She feels sorry but it's too late because Bowie is already gone.
With Bowie gone, Bex cheers Andi up by taking her on a shopping spree at the local vintage store in She's Turning Into You. When Jonah asks Andi for gift-advice for Amber, Andi takes him to The Fringe where Bex takes the opportunity to give Andi make-up in front of Jonah Beck, making Jonah see Andi in a different way. Jonah calls Andi pretty. Andi and Bex hang out together at The Spoon Diner during which Andi wonders why Bex left in the first place because they could have been having that much fun all the time. Unfortunately, Celia gets mad at Andi and Bex for coming late for dinner and wonders why Bex hasn't gone yet. Andi tries to defend Bex, and blames Celia for wanting to send Bex away again. This causes an ugly debate between Celia and Bex about whose fault it was for Bex leaving. Celia says she did it for Andi's welfare but this only gets Andi mad. She storms out. The next day she puts on make-up just to piss off Celia before going to school. Celia is worried that Andi is turning into Bex.
When Bex picks Andi up after school, none of them want to go back home. Bex has already got an apartment for them to move in together. In "Home Away From Home," Andi struggles to adjust to the new living conditions with Bex. Food is a problem. Electricity is a failure. And Bex can't do Andi's laundry as well as Celia used to. Andi doesn't want to disappoint Bex by complaining. But when she realizes she needs art supplies, she and Bex sneak back into Andi Shack to get supplies. But, they're busted by Celia and Ham. Celia says how much she misses having Andi and wishes Bex could move out alone and let Andi stay. Celia feeds her and they head back to the apartment. Andi then starts sneaking back into Celia's house to eat and to get her laundry done. Bex finds out and is mad that Andi lied to her. Andi apologizes for going behind Bex's back.
It becomes almost impossible for Andi to eat at the apartment because the oven and microwave are not functioning. Bex feels bad and takes Andi back to Celia and asks them to feed them. She says that she wants the best for Andi and she's not ready to raise Andi alone. However, when Andi is left with Celia and Ham like old times, she realizes that she misses Bex and doesn't want things back the way they were. These are new times. So, she asks them to take her back to Bex's apartment. Bex is so happy to have Andi back. Andi for the first time calls Bex, "mom" which makes Bex very happy.
In Were We Ever?, Andi runs into trouble with Dr. Metcalf, the new Jefferson Middle School principal for violating dress code. Principal Metcalf tells Andi that by wearing leggings, she's distracting boys with her body parts. So Andi, Buffy and Cyrus tell Bex about their issues with the unreasonable dress code. Bex encourages them to protest against it by marching to school while wearing prison outfits. Andi leads the protest along with Buffy and Cyrus but they're quickly summoned into the Principal's office. The principal threatens to suspend them if they don't change. Andi and her crew get energized after seeing other students joining the protest. She asks Jonah Beck to join the protest but he refuses because he's too preoccupied with the Space Otters Frisbee Team photo. During the team photo, Andi shows up with her protest outfit and Jonah tries to convince her to change to the team jersey. Andi refuses to change to the team's jersey unless Jonah can tell her why she is wearing the prison outfit. Jonah can't remember. So, Andi walks away, realizing that Jonah hardly pays attention to what's important to her.
Andi gets her first victory when the protest helps her force Principal Metcalf into a truce. While celebrating their victory, Jonah comes over and calls Andi to walk with him. He apologizes to her for not paying attention to her and for being preoccupied by Space Otters team photo. He asks Andi to show up the next day for the photo retake but Andi refuses. Andi stands up to Jonah for constantly asking her for favors - including buying birthday gifts for Amber. Yet she keeps doing it just because Jonah Beck asks her to. She never loved frisbee. She only liked it for Jonah. But now after the protest, she feels liberated. She feels like she can go for what she wants without having to make her life revolve around Jonah Beck. Jonah apologizes but Andi tells her it's not his fault. It was her fault for misleading him by doing anything he asked instead of standing up for herself. So, now she's quitting Space Otters frisbee team. Jonah asks if they can still be friends but Andi asks if they were ever really friends. She walks away in confidence. Finally free. Liberated.
In Best Surprise Ever, Andi's wish of finally getting a real normal family rises when Bowie comes back in town. Bowie picks up Andi from school and tells her that he came back because the universe told him to come back to Bex. Andi sets up Bowie and Bex in the perfect mood by asking Bowie to play the song he wrote for Bex. She goes to bed, leaving Bex and Bowie dancing and hoping that Bowie will stay. The following day she's disappointed to find Bowie gone. Bex admits that she likes Bowie but reminds Andi that Bowie is unpredictable and he's not someone they can depend on. Andi finds Bowie in the mall and tries to convince him to come back because both him and Bex love each other. Bowie explains that he needs to prove himself to Bex that he's dependable. While still talking with Andi, Bowie finds an engagement ring in the jacket. Both Andi and Bowie conclude that this is a sign from the universe for Bowie to marry Bex.
Andi continues to push Bowie to propose to Bex in Hey, Who Wants Pizza?. She gives him proposal ideas. However, when Bowie finally asks Bex, Bex only responds with "um..." instead of agreeing to marry Bowie. Andi remains hopeful that Bex just needs time and will eventually say yes. In Chinese New Year, Andi learns that Bex is not planning on marrying Bowie. She asks Bex to tell Bowie because he's going to be heartbroken. But it turns into a disaster when Bowie tries to bring up the proposal during the Chinese New Year festival. Andi later realizes that Bex is reluctant to marry Bowie because of the boy in the picture from Shhh!. Apparently, Bex after saying he's nobody and ripping the picture apart and throwing it into a trashcan, Bex later taped it together and put it inside another box of toaster tarts. Andi figures out that he is the reason she can't marry Bowie. She helps Bex burn the picture in "Friends Like These" to help her move on and find closure. Andi is happy when Bex and Bowie start hanging out again.
Andi's potential relationship with Jonah Beck is revived in "Hey, Who Wants Pizza?" following Jonah's break up with Amber. Jonah returns The Bracelet that he had given to Amber after Andi made it for him. He also asks Andi to attend the Space Otters Frisbee Team party. At first, Andi is reluctant because she's trying to get Jonah Beck out of her head but Bex convinces her to go. After the party, Jonah asks to speak to Andi alone during which he tells her about her break up with Amber. He also tells her that he likes being around her. She gives him the bracelet, saying that it belongs to him. After that, her crush on Jonah Beck increases. It gets so bad that she replies with "dimples" when Jonah asks her anything. Jonah comes over to Bex's apartment and offers to go with Andi to CeCe's house for Chinese New Year feast. They finally hold hands in "I Wanna Hold Your Wristband."
In a surprising twist, Andi makes an unlikely friend when Amber starts working at The Spoon Diner. At first, Andi becomes very uncomfortable about it. In Friends Like These, she is surprised when Amber comes over to make a small talk. She's surprised that Amber has feelings but Amber tells her that she just needs to get to know her better. Andi and her friends even try to ditch The Spoon to avoid but they can't find a better place. After seeing Amber selling some of her clothes, she figures out that Amber might be in some tough financial situation. She buys one from Amber. In The Snorpion, Andi overhears Amber on the phone and realizes that Amber's parents are fighting. She talks to Amber about the situation and offers her a place to sleep for the night. Buffy advises Andi that Amber is a snorpion (snake, and a scorpion) and can't be trusted but Andi goes ahead anyway. During the sleepover, Amber and Andi have the most fun of their lives. But then things change when Amber convinces Andi to sneak out into a prohibited ferris wheel for a free-ride. During the ride, Andi's phone rings while she is at the top of the ferris wheel. When Amber notices that the call is from Jonah, she stops the ride and forces Andi to apologize for stealing Jonah from her. After hearing police sirens approaching, Amber runs away, leaving Andi to be busted and taken to the police station. Andi is picked up by Bex and Bowie. After that, she breaks up the friendship with Amber.
Andi finally learns what caused Bex to leave home in "Mama." Bex tells her that she left because Celia was so hard on her and she criticized everything Bex did. Celia says that teen mom Bex didn't really care about school or anything and she wasn't fit to raise a child. Andi already knows that there was tension between the two. So, what was the final thing that caused Bex to leave home? Ham explains that on the day Bex left, Celia and Bex had been arguing all the way from the hospital because Celia had presented herself as the baby's mother and the doctors treated Bex as a little girl. In the heat of the argument, both Celia and Bex forgot to bring baby Andi back from the car. Ham brought the baby into the house, after which baby Andi said her first words, "mama." The problem is, she was calling Celia mama. Not Bex. This made Bex realize that she had no chance of truly being seen as Andi's mother. So, Bex left home, leaving Andi to be raised by Celia. After hearing the story, Andi blames herself for causing Bex to leave but Ham assures her that there was already too much tension before Bex left. It was bound to happen.
Later that day, Celia tells Bex that she is going to be selling the house, which means Andi would lose Andi Shack. She asks Bex to deliver the bad news to Andi but Bex doesn't want to do it and thinks Celia wouldn't follow through. So, she keeps Andi in the dark. A few days later, in "I Wanna Hold Your Wristband," Bex realizes that Celia was serious about selling the house. Bex and Bowie are forced to tell Andi that she is going to lose Andi Shack. Andi does not take the news lightly because Andi Shack is her life. She gets sad and angry. She runs to the Andi Shack, locks herself in and lies on the floor. Hopeless.
In Head Over Heels, Andi's relationship with Jonah starts getting rocky. Jonah asks Andi out on a date but then he asks Buffy to come along too. During the date, it is clear that Jonah and Andi don't have the same chemistry that Buffy and Marty have. It gets worse when Jonah falls and Andi laughs at him. Jonah becomes embarrassed and refuses to talk to Andi. They get even when Andi falls and Jonah laughs back at him.
To save Andi Shack in There's a Mack in the Shack, Andi starts spending time at CeCe's house since CeCe had agreed not to sell the house as long as Andi is using it. Bex is skeptical of the arrangement, thinking that Celia is the one manipulating Andi. The bond between CeCe and Andi becomes so strong that CeCe even starts learning how to dance so she can dance with Andi. She even lets Andi skip school so they can go shopping together. This makes Bex furious but at the end of the day, it helps save Andi Shack. Celia agrees to remove the house from the market.
In You're the One That I Want, Andi starts to become jealous when she notices Jonah hanging out with the new girl, Natalie. Amber gets into Andi's head by telling her that Jonah did the same thing when he was dating her, claiming that Andi is just a friend. Andi refuses to listen to Amber. To help Andi, Buffy and Cyrus spy on Jonah and Natalie but they find nothing. So, Andi is happy for a while before realizing that Jonah chose to go to Natalie's video taping and forgot about his sing-along plans with Andi. Amber talks some sense into Jonah, making him come to Andi's event instead. But deep down, Andi can tell that Jonah would rather be doing something else.
In A Good Hair Day, Andi discovers that it's Bowie's birthday. She convinces Bex to throw Bowie a surprise birthday while she and The Good Hair Crew are at the Renaissance Faire. After the birthday party, Andi calls Bowie "dad" for the first time.
But that happiness is shortlived when Andi learns in "Miniature Gulf" that Bowie is seeing another woman, Miranda Patrick. Andi wants to meet Miranda so she can see if she's good enough for Bowie but both Bex and Bowie want her to stay out of it. Miranda even has a little daughter, making Andi feel less special.
Andi's relationship with Jonah Beck comes to an end in "We Were Never" when she discovers that she and Jonah were never really a couple. Jonah returns The Bracelet, broken, to Andi and tells her there is no need to fix it. Andi fixes the bracelet while also worried that her relationship with Jonah might be in trouble. When she returns the bracelet to Jonah, Jonah refuses to accept it, claiming that he's not a bracelet guy. He tells Andi that wearing the bracelet would make it look like they're boyfriend-girlfriend. All this time Andi thought Jonah was her boyfriend. She is crushed. She throws the bracelet in the trash but Bex picks it up and puts it in a new, smaller memory box for Andi.
Andi continues to stress out about Jonah during Cyrus' Bash-Mitzvah!. Bex, Buffy and Cyrus are there for her to help her through it. To show Andi that she's not alone in what she's going through with Jonah Beck, Cyrus comes out to her, revealing that he has a crush on Jonah Beck. Talking with Cyrus about their feelings for Jonah Beck helps Andi feel a lot better. Bex takes Andi to the caricature artist, Walker to draw a portrait of them but Bowie comes over and makes things awkward because of the Miranda Patrick situation. Afterwards, Andi is surprised when Walker walks to her and shows her a very beautiful drawing of her. Andi is impressed by Walker's skills and they start hanging out together for most of the party. They even go to a photo booth together but Walker is called to return to his station.
Andi is surprised when Jonah says that he still wants them to hang out together. According to Jonah, nothing really changed. He simply doesn't like labels. Andi refuses to let him in. She tells him that she used to be so obsessed with him but now she's over him. Jonah admits that he liked all the chase but Andi is not okay with it. Jonah leaves and gets a very bad anxiety attack. Later at home, Jonah comes over to talk to Andi. He tells Andi that something happened to him and now he's ready to be boyfriend and girlfriend with Andi. He asks Andi if she will accept to become his girlfriend.
Like mother, like daughter, Andi just replies with "um..." In Better to Have Wuvved and Wost, she tells Bex that she said "um" because she's not sure she wants to be with Jonah, yet. She finally clarifies to Jonah that even though he's now ready to be called "boyfriend," she doesn't know what she wants yet. He needs to give her time and space especially now that she's worried about Buffy leaving.
In Perfect Day 2.0, Andi attempts to recreate a perfect day with her friends before Buffy has to leave. When things start to go wrong, Andi takes every measure possible to not have to call Bex for help, to the dismay of her friends. In the end, the friends realize that their adventure for the day was the perfect day.
Andi has her first big mother-daughter fight with Bex in Truth or Truth, when a BFF quiz on a magazine leads to Bex admitting that she regrets not saying yes when Bowie asked to marry her. When Bex says that she wasn't ready at the time, Andi thinks that Bex is trying to blame her because she's the one who pushed Bowie to propose when Bex wasn't ready. She insists that Bex should tell Bowie the truth but Bex refuses, saying that it's too late and Bowie has already moved on and she doesn't want to hurt him. Andi is mad that Bex cares about what Bowie wants but doesn't care about Andi being with her father. This leads to a heated argument between Bex and Andi. When Bex goes to CeCe's house to seek help reaching through to Andi, Andi sneaks out of the apartment and goes straight to Bowie's truck. She asks Bowie to let her stay with him. She returns to Bex after one night in "A Walker to Remember."
In "A Walker to Remember," Andi gets a call from Walker, the artist from Cyrus' Bash-Mitzvah!. Walker asks her to hang out during which she helps Walker complete a painting. They sign their names together. Jonah sees it later and becomes more concerned that he might be losing Andi to Walker.
Andi finally meets Miranda (bowie's girlfriend) and her 7 year old daughter Morgan officially in "Crime Scene: AndiShack!." She is pressured by Bowie and Miranda to stay with Morgan in the Andi Shack while Miranda is running some errands. She tries to be nice to Morgan but Morgan doesn't appreciate or like her back. Morgan even destroys a special bracelet that Andi was making for Bex out of the bracelets they wore at the hospital when she was born. So, Andi puts the remaining pieces inside a shiny silver box. The box goes missing and after looking everywhere, Andi suspects that Morgan took it. Bex believes her but Bowie and Miranda don't believe her. While confronting Morgan to admit that she took it, Andi is surprised when Bowie mysteriously finds the box at a place she already looked. She wishes Bowie could believe her.
Andi gets her first kiss in "Andi's Choice." She is trying to figure out her feelings for Jonah and Walker. But Jonah writes and performs a beautiful song for her, she goes and kisses him. In For the Last Time, she is impressed with Jonah when he encourages her and Cyrus to build a time capsule as a surprise gift for Buffy leaving. In Buffy in a Bottle, Andi calls Walker to end things with him since she's with Jonah now. However, Walker gives her shoes he made for her as a gift and insists that she should take them. When Jonah sees the shoes, he becomes jealous of Andi and Walker. Andi realizes that she needs to tell Jonah that she's his girlfriend. But, Jonah comes in with Natalie, which makes Andi jealous. She needs someone to talk to but Bex is busy working with CeCe on her new Cloud Ten business. She wishes Buffy was there. Luckily, Buffy returns to town since her mom's program was cancelled.
In Keep a Lid on It, Andi tries to make a new bracelet for Jonah because the original bracelet was the symbol of their relationship. She is surprised when Bex reveals that she kept the old bracelet in a memory box. Buffy encourages Andi to give the bracelet to Jonah, confirming that they're boyfriend-girlfiend.
- Main article: Andi and Bex
- Bex is Andi's mother. Out of all her relationships, Andi shares the most personal bond with her. Prior to discovering Bex's identity as her mother, Andi thought of Bex as her adventurous, cool, older sister, and even looked up to her. However, she was concerned that she was merely an insignificant part of her "sister's" life, and was upset that she didn't know her better. Although at first excited about Bex's arrival at the beginning of the series, Andi slowly begins to realize how far she and Bex have drifted apart. This later worsens when Bex admits to being Andi's mother, causing the tension between the two to increase.
- Despite this, Andi slowly comes to accept the fact that Bex is her mother, and the two struggle to adjust to this change. However, Bex continues to act as more of a sister to Andi rather than a mom, which Andi herself notices, admitting that she feels uncomfortable being the "adult" in their relationship (referring to Bex's careless attitude).
- While their relationship isn't perfect, the two gradually become closer and form a strong and firm bond of trust. However, it did take some some time, due to Bex's secretive attitude around Andi in the beginning. An example of this was when Bex refused to reveal the identity of Andi's father (Bowie Quinn) to her, something which often caused Andi to lash out at her. But they eventually got there after Bex resolved to no longer keep secrets from Andi, and vise versa.
- Andi's role in Bex's life also caused her to become more responsible, although she does, at times, pull Andi into trouble rather than the other way around. Despite this, Andi starts to see Bex more as her mother rather than sister, and eventually begins referring to Bex as Mom, to the latter's delight.
- Main article: Andi and Bowie
- Bowie is Andi's father. Having not known that Bex was her mother for the first 13 years of her life, Andi remained unaware of her father's very existence. However, when Bex eventually revealed the secret, Andi became determined to find out who her father was, and pressured Bex to tell her. When that didn't work, she began looking for clues herself. Eventually, Bex decides to become more open with Andi, and sends Bowie an email. This causes Bowie to come visit Bex, but to Andi's immense shock, Bex reveals that Bowie is her father instead.
- At first, Andi is overjoyed by his arrival. She even agrees to skip school to spend the day with Bowie, where the two continue to learn more about one another. Bowie's adventurous nature and faith in the universe surprise Andi; however, she gradually begins to see much of Bowie's personality in her own. The two bond on their many similarities, and Andi quickly becomes attached to him. Bowie even misses his tour for a short time just to remain with Andi and Bex.
- However, the longer Bowie stayed, the more Andi became annoyed by him. She is distressed when Bowie embarrasses her at one of her games, and even tells Bex that she wished for some space. Andi gradually becomes more hostile towards Bowie, to his dismay. The last straw was when Andi caught Bowie going through her laptop, accusing him of invading her privacy and yelling for him to leave. However, Bex discovers that Bowie had been working on a music video of their time together, but by the time Andi goes after him, Bowie is long gone.
- Bowie later returns for Andi and Bex, where the two apologize to each other and make ammends. Andi decides that she does love her father, and even starts hoping that Bowie and Bex will get back together and marry.

- However, Jonah's relationship with Amber eventually starts to crumble, and during that time, he is confronted by Andi, who apologizes for allowing him to use her for his personal gains. Having not realized that, Jonah begins to feel guilty, and at the same time, develops feelings for Andi which leads to his breakup with Amber.
