Series 5

In "Franky", Mini, the leader of her group, is the first to call out Franky on her androgynous clothes. Mini eventually clashes with Franky during a violent field hockey game. Afterward, however, Mini says they should let bygones be bygones and says Franky can hang out with her two friends, Grace and Liv. They invite her into their group, proceed to take MDMA, and go shopping. However, Mini starts to antagonise Franky, who rejects her materialistic outlook and looks to steal Grace and Liv away. After finding out why Franky left Oxford (she was severely bullied), Mini persuades her boyfriend Nick to post embarrassing photos of Franky around the college, which leads Mini and Franky to fall out.

Later, at Mini's party, Franky confronts Mini about her behaviour and Mini reveals that Franky was only invited as a joke and Grace and Liv were in on it. After Franky leaves in tears, Liv tells Mini that she needs to be more mature and act like someone who's old enough to be in college. Mini then asks Liv where Grace went, not knowing that Grace, having liked Franky from the start, had left the party to hang out with her and make amends.

In "Rich", she is seen briefly with Liv, crashing Grace's ballet practice, where she pretends to have no problem with Grace hanging out with Alo, Rich, and Franky, although she later insults them.

In "Mini", Mini is arranging a charity fashion show with her school committee but is outraged to discover that Grace has recruited Franky to help with the clothing designs. Out of pride, she handles it with her boyfriend, Nick Levan. Nick, meanwhile, is hoping to consummate their three-month relationship. Unbeknownst to Nick, Mini is still a virgin but is afraid to admit it and is scared of losing her virginity. She attempts to put off having sex for several days until she and Liv go on a double date with Nick and his friend, Rider, at the Bowling Alley. To delay sex further, she hides Nick's keys in her handbag, but Rider suggests they return to his place. Rider and Liv start having sex, and Nick pressures Mini to do the same. However, due to some medication she intentionally took earlier, she vomits on him first, forcing him and Liv to take Mini home and stay the night.

The next day, Mini wakes up, sees Liv and Nick sleeping beside each other, and misunderstands the situation. During the day, she discovers that the students know about her vomiting incident (Grace and Franky and their group mock her because of it) and believes that Liv has spread the story. She then attempts to call Liv about the fashion show, and upon finding Nick's phone in the changing room, she discovers that Liv has placed three calls and then sees her dancing with Nick outside. Fearing the worst, she confronts Liv and finds that the costumes don't fit her or the other models and that there are not enough, and the routines are still yet to be choreographed. Overwhelmed with pressure, she faints, is informed that she can no longer produce the show, and is sent home.

Realizing that stalling sex risks losing Nick, Mini dresses up, returns, and discovers that Grace and Franky's designs have earned a standing ovation. Later, at a rave, Mini confronts Liv about her apparent attraction to Nick and fights with her and Grace before storming out and crying. Seeing this, a compassionate Franky approaches and talks Mini into returning. As they return, Mini sees Nick and Liv leaving a small janitor's closet rearranging their clothes, and realizes they just had sex. Mini then entices Nick to take her back to his place, and finally loses her virginity to him. The next day, she finds Nick has gone to practice and sadly returns home.

In "Liv", Mini, remembering Franky's kindness, decides to make amends with her and her gang, forcing Liv to do so in the process. After bringing out a bag of spliff, they begin an impromptu party at Liv's home. When Liv returns the next day with Matty, they discover Nick and Mini having sex in Liv's bed. Nick, upon emerging from the covers, recognizes Matty at once as his brother and immediately warns Liv to stay away from him. Liv and Nick admit to Mini that they had sex, so she can no longer pretend it didn't happen. Enraged, Mini later forces Liv to drink an entire bottle of vodka as an apology (after hearing she had done the same thing with Matty) before leaving her to suffer.

In "Nick", Nick and Mini have another awkward sexual encounter, motivated by Nick's jealousy that his brother has been having sex with Liv. Later on, Mini spitefully dances with Nick's friend, Rider, at a bar. Drunk and angry, Nick punches Rider in the face, and in an ensuing confrontation with Mini, she reveals angrily that she had known all along that he had been cheating on her and finally breaks up with him.

In "Alo", Mini joins the gang at Alo's farm for a party. At the party, she sidles up to Franky on a couch and reveals to her that she is aware of Franky's crush on Matty, though Franky vehemently denies it, and encourages her to pursue him ("Liv'll do it to you in a second"). Later on, while continuing the party at Nick's house, Alo collapses on a couch beside Mini and weeps at having messed everything up. Mini consoles him, telling him he is 'alright' and later dances with him.

In "Grace", Mini is a member of Grace's production of Twelfth Night, and develops a closer friendship with Franky. At a girls' night at Grace's house, she discovers for the first time that Grace's father is David Blood, the school headmaster. Mini talks Franky into discussing her sexuality. Later on, while standing in for Liv (who had quit), Mini hesitantly kisses Franky at the suggestion of Grace, much to the shock of Rich and Alo.

In "Everyone", Mini has become protective of Franky after witnessing her confrontation with Liv and Matty at the end of the production of Twelfth Night. Before Grace and Rich's wedding, she angrily warns Matty to stay away from Franky, and tries to advise Franky that she "deserves better." However, when Matty and Liv lose confidence in Alo's navigation skills, they invite Franky to join them, and despite Mini's pleas, she goes with them. Mini, however, continues to worry about what will happen. Eventually, she deserts Alo and Nick and finds the three. She runs into Liv, who separated from Matty and Franky, and reveals her fears of losing Franky, causing Liv to ask if Mini has a crush on Franky, which Mini does not deny. The two reconcile. After seeing Franky run past, having a panic attack, Mini stops Matty and realises they have attempted sex. Fearing for Franky's safety, the three all run after her. Franky accidentally trips and falls over the side of a cliff. After Liv pulls Franky to safety, a horrified Mini hugs Franky. She eventually calms Franky down, and the two talk briefly outside Grace's marquee.

Series 6

In "Everyone", Mini goes on a holiday to Morocco with the rest of the gang. She is shown to have developed a crush on Alo, who shows signs of attraction towards her. At the villa, she is annoyed that Rider has failed to get the water running, eventually punching him in the face for making sleazy jokes about her. The gang later attends a party, where Mini notices Alo stealing a phone from someone's clothes. The following day she wakes up and finds Franky, Liv, and Nick all passed out. She successfully gets the water running and takes a shower in the pool. She goes to Alo's room and seduces him, demanding he say nothing about it. When the group later attends another party, they agree to continue their sexual relationship. Mini's crush on Franky has faded, and she mentions to Liv that she prefers Franky's old personality.

In "Rich", Mini is waiting for Grace to awaken from a coma. This episode first mentions her when she texts Alo asking him where he is. Later Rich and Alo are slumming in the Blood's house. Rich catches Mini and Alo in the middle of having sex, and Mini swears him to secrecy as she wants to keep her relationship with Alo private. She confronts him on why she wasn't told that Grace had awoken. She is later seen leaving the Blood's house and is caught by Liv and Franky when Rider comes to pick her up. When asked why she was there, Rich covers for her, saying she was collecting her straighteners. Later at the party, she is seen dancing with Liv and Franky before later on kissing a random guy, whilst Alo looks on, obviously jealous.

In "Alex", Mini is first seen in the corridor where Liv accuses Mini of avoiding her. When Liv brings up the topic of Grace, Mini leaves. She is then seen in the canteen by Alex sitting across from Liv, and neither speak. Later in the episode, Mini is at the Pub with the gang, downs shots, calls the others boring, and begins dancing with a boy. Mini is watched by an uncomfortable Alo. Alex comments about Mini and Alo as a couple, which Liv is quick to shoot down. Mini then goes to Grace's memorial with Franky and Liv, but their presence proves disruptive. Franky interrupts a ridiculous tribute to Grace and Liv, then smashes a keyboard and flashes the mourners for the over-the-top arrangements. Mini goes to a party on Alex's boat with the rest of the gang but still seems distant. When Liv tries to talk to her, Mini quickly brushes her off and says she's okay. Mini and Liv later discover the body of Alex's grandmother, and Mini screams for Alo. Mini then helps to send Alex's grandmother's coffin out to sea, but is seen to be crying as Alex reads a postcard written from his grandfather to his grandmother. Mini is then seen leaving the ceremony as Franky says that if Alex's gran sees Grace, she should tell her that they miss her.

In "Franky", Mini is seen with the rest of the gang sitting her mock A-levels and is then confronted by Franky over a comment she makes as Luke drops Franky off at Roundview. Franky accuses Mini of blaming her for the accident. Mini then responds by asking her what is wrong with her.

In "Mini", Mini is having sex with Alo in a nightclub toilet, where he breaks the terms of their 'no-strings-attached' relationship by declaring he loves her. Freaked out, she returns home, but is kept awake by her mother having sex. After arguing with her mother, Shelley, about it the next day, Mini calls her father, Gregory, and arranges to meet at a local aquarium. The meeting goes well, and Mini begins to rebuild her relationship with him, to her mother's chagrin. As she integrates into his life, including arranging to flirt with his assistant, she distances herself from her friends at school. However, she is pregnant. Only Franky notices, recognizing Mini's regular vomiting as morning sickness; Mini's defensive attitude when questioned about it confirms Franky's suspicions. Although Franky promises silence, Mini's temper alienates her from the others, including Liv and Alo.

Things come to a head when the gang crashes a party that Gregory arranged, and Alo, after snorting cocaine, is compelled to march over and confront Gregory's assistant, whom he believes has feelings for Mini. This upsets other partygoers, getting Alo thrown out and Mini declaring they're finished. Mini then seduces Gregory's assistant, and they go off to have sex, but fearing for his job, he politely leaves. He is replaced by Liv, who wants to talk to Mini about why she's acting so strangely. After Mini makes Liv storm out, Franky questions Mini about her pregnancy and discovers that Mini hasn't come to terms with it. After some gentle coaxing, Mini confesses to her father. They arrange to fly to Sydney, and Mini goes home to pack. Her mother implores her not to go, but Mini coldly brushes her off. She returns to her father's home, but finds it empty – he has emigrated just as Mini had feared he would, leaving a note saying "Sorry. I love you" and a cheque for £500. Mini tries to ring him, but he is already on the plane, and she collapses in the kitchen, ripping up the note as she cries. She then goes to Alo hoping to make up with him, but he coldly tells her that he is fed up with her treatment and asks her to leave. She returns home and discovers her mother weeping in the kitchen. Her boyfriend comes outside to smoke a cigarette and finds Mini there, and she implores him not to do what her father did to her mother. Franky escorts Mini to an ultrasound clinic the next day. There, an initially reluctant Mini is implored to look at the scan and breaks down in tears of joy as she sees her baby for the first time on the screen.

In the next three episodes, Mini attempts to tell Alo she's pregnant, her courage fails her.

In "Mini and Franky", Mini has been spending all her time with Franky, who is excited about the baby. However, on the way to an ultrasound appointment, Mini collapses and fears something is wrong. She is taken to hospital, where she is told she is having a baby girl and is assured that her baby is fine. A few minutes later, during an ultrasound, Shelley and Alo walk in and finally find out that Mini is pregnant. Alo reacts badly, throwing up upon finding out, and Shelley wants her to give up the baby, seeming not to care about Mini's feelings, even calling her a "fucking fool" for not wanting an abortion. When her mother begins to make arrangements to have the baby put up for adoption, Mini runs off with Franky. They go to a homeless shelter masquerading as a lesbian couple, but are kicked out the next day. Unwilling to lose the only maternal figure in her life, Franky tries to convince Mini to go to Oxford with her, but Mini instead decides to go home, stating she will return only if her mother allows her to keep her baby. When Mini arrives home, her mother tells her how she almost miscarried with Mini. Shelley decides to let Mini keep the baby, and the two reconcile, which sends Franky running out of the house in tears. Rich picks up Mini and takes her to Alo's farm where he has arranged for them to live. While dancing with Alo, Mini discovers blood running down her leg.^[7][8]

In "Finale", after time in the hospital, Mini is recovering from a near miscarriage. When Liv lashes out at Franky for her melodramatic behaviour, Mini stands up for Franky and calls Liv off and then orders her out of the room. She then hugs the crying Franky and advises her to confront Nick and Matty over their love triangle. Alo gets Mini's gynaecologist to allow her to go to Alex's party as long as she does not dance or drink. At the party with Liv, Mini goes into labour and then later gives birth to her daughter, whom they (presumably) name Grace McGuinness Creevey, with Alo and Liv by her side.^[9]
