The affair is soon exposed, causing Max to leave Walford. Lauren is angered by Tanya's actions, but is devastated to learn that Tanya has been diagnosed with cervical cancer. Lauren promises to support her but struggles to cope with her mother's illness. She starts drinking excessively and almost ends Darren Miller (Charlie G. Hawkins) and Jodie Gold's (Kylie Babbington) relationship by having sex with Darren in the car lot – hours before the wedding. She also casually dates Tyler Moon (Tony Discipline) until realising Whitney is still in love with him. Max returns to Walford, and when Lauren learns that Tanya has stopped her treatment, begs him to stay and reveals her illness so he stays. Lauren's rebellion continues and she reunites with her old friend Lucy Beale (Hetti Bywater) at Pat Evans' (Pam St Clement) funeral. After getting drunk at the funeral, she is berated by her parents and given a private consultation with a GP. Lauren withdraws from school, and is employed at the car lot. She resumes drinking and tries to conceal this from her parents. Her drinking is so heavy that, on a night out, Lucy tells her to go home but Lauren ignores her, insisting that she is fine. Lucy loses her and she is found passed out in the street. Lauren tells her parents her drink was spiked before stating she is mature enough to make decisions. She then decides to move out. On her 18th birthday, a drunken Lauren belatedly arrives at a family party, organised by Tanya. After being sick, Lauren admits to her parents that she is uncontrollable and promises not to drink any more. She moves back home after not being able to cope with the laziness of her housemates. Lauren and Lucy go out where a drunken Lauren shares a kiss with a stranger, Dan, who drags her into his car. After Lucy manages to drag her out, they argue and Lauren storms off. Lucy finds her unconscious and takes her to hospital but Lauren discharges herself. Lauren returns home to find Lucy has already told Max, Tanya and Ian everything. Angry, Lauren argues with her family and leaves, meeting Dan. After she rejects his advances, Lauren goes to Lucy's house and Lucy tells her that she does not want anything more to do with her.
Lauren meets her cousin, Joey Branning (David Witts), and is attracted to him. Her friendship with Lucy begins to improve after Lucy's father Ian Beale (Adam Woodyatt) disappears and Lauren helps find him. Joey and Lucy start dating but Lauren learns that Joey had cheated with Whitney, and urges her to tell Lucy. Lucy ends the relationship and the girls take revenge by handcuffing him to playground equipment. Lauren decides to free him so he does not lose his job, and he tells her she is jealous that she did not get a kiss, so she slaps him. Joey is working at R&R when he sees Lauren flirting with a group of men so he throws them out and takes Lauren home. Lauren drunkenly kisses Joey but he rejects her. The following day, Joey explains that he rejected her because she was drunk and they kiss again. Lauren realises she cannot be with her cousin, so resists. Eventually, sexual tension mounts between them and they start a secret relationship. Joey's father Derek Branning (Jamie Foreman) finds out when he sees Joey and Lauren passionately kissing in the car lot office. Derek threatens Lauren so she and Joey plan to leave Walford. As they drive away in Derek's car, a drunk Lauren loses control of the car and crashes into a shop. Derek helps rescue them from the burning building and makes Joey take the blame for the crash. At the hospital, Lauren tells Tanya about her relationship with Joey and Derek blackmails Joey to end it. Heartbroken and distraught, Lauren continues to drink and Tanya realises that Joey is still in love with Lauren. Lauren later drunkenly reveals her relationship with Joey to the rest of her family. Joey leaves Walford after Derek dies but returns and reunites with Lauren, where Lucy witnesses them kissing. When trying to justify her relationship, Lauren is shocked when Lucy calls her selfish and undeserving of Joey's love, so Lauren considers telling the police the truth about the car crash, but Joey convinces her not to. Lauren and Joey's relationship is publicly revealed, though people start to accept it. Lauren discovers that Tanya has lied about missing a hospital appointment, and as Tanya refuses to talk, Lauren starts drinking again. Lauren destroys her mother's wedding gown and cake before Tanya and Max remarry. She later bonds with Max's secret wife, Kirsty Branning (Kierston Wareing), upsetting Tanya.
Lauren finds out that Kirsty is pregnant, unaware that Kirsty is lying. At a party, Lucy spikes Lauren's drink so she drunkenly reveals that Kirsty is pregnant. Lauren falls out with Joey, who breaks up with her over her behaviour. She applies for a job as a waitress with Whitney at Ian's new restaurant but Lucy gets Joey to be Lauren's test customer so Lauren will fail. Whitney gets the job but purposely withdraws so that Lauren gets the job instead. She tries to make Joey jealous by kissing Tyler, who is engaged to Whitney, but it fails and Whitney ends their friendship and Lucy offers the job to Whitney. Lauren's drinking gets worse, though she believes she is not an alcoholic and tricks her step-grandmother Dot Branning (June Brown) to give her money, which she uses to buy alcohol. Tanya is angry when she discovers this. Lauren then steals £20 from her grandmother's purse and when Tanya discovers this, she compares her to her aunt, Rainie Cross (Tanya Franks). Disgusted, Lauren attempts to buy more alcohol but Kirsty refuses to serve her, following Tanya's wishes. Lauren walks outside and confides in Joey but Lucy sees this and starts intimidating Lauren so she punches Lucy and smashes the café window. Lauren is arrested but Lucy decides not to press charges. Ian gives Lauren her waitress job back, but is sacked on the opening night for getting drunk and spills drink on a guest. Tanya and Max find bottles in Lauren's bedroom and decide to keep her locked in the house. She believes Lauren is showing no signs of withdrawal but Lauren reveals she has been drinking vodka from a water bottle, so Tanya realises she is addicted. Tanya keeps Lauren locked in her room but her withdrawal leads her to climb out of the window and Lauren says that nobody can stop her from drinking if she wants to. The next day, Tanya tells Lauren to leave after she destroys Abi's revision notes, and she stays with Max and Kirsty. Tanya asks Peter (now played by Ben Hardy) to spend time with Lauren, but their date is sabotaged by Lucy, so Lauren gets drunk again and leaves with a group of strangers. When she returns, her skin and eyes are yellow and she collapses in pain, so she is taken to hospital and diagnosed with alcoholic hepatitis. She is warned that she could die if she doesn't stop drinking. Lauren returns and sees Joey so tries to find him. She confronts Lucy over her relationship with Joey, but Lucy refuses to answer, so Lauren concludes that they are together and tries to get a drink but is refused service. Tanya takes her home, where she admits that she cannot cope with her parents' constant arguing. Ultimately, Tanya blames herself and takes Lauren to a clinic in Exeter, believing a change of scene could help.

[10] However, after finding a previously torn off piece of a page from Emma's case files and trying to use Emma's phone, Lauren starts to doubt if she should marry Peter and drinks most of a half-bottle of whisky in Max's office. When Lauren nearly faints, Stacey buys her a test and discovers that Lauren is pregnant. Stacey confronts her about it but Lauren reveals that she knows who killed Lucy, but refuses to divulge the identity to the police. When Stacey calls the police, she is upset at her inability to keep a secret but hands in most of Emma's case files, while keeping the torn-off piece. She writes a card addressed to Jane, saying that Lucy was killed at home, and abruptly leaves to book an abortion. However, during the consultation, Peter interrupts her and offers to support her through all her issues. Lauren says she is confused and that she knows what happened to Lucy, leading him to discover the truth about the murder at home. When Peter decides to emigrate to New Zealand, he asks Lauren to go with him. She initially refuses, planning to join Tanya in Devon but after he tells her that his brother Bobby Beale (Eliot Carrington) is Lucy's killer, she changes her mind and decides to go to New Zealand. They dispose of Emma's remaining evidence and SIM card, deciding not to tell the police about Bobby being Lucy's killer. She says goodbye to Max and Abi and leaves with Peter, taking an outfit for their unborn child with them.
A heavily pregnant Lauren returns for Max's murder trial, saying she knows who killed Lucy. As she threatens to tell everyone about Bobby, her waters break. She later gives birth to a baby boy who she names Louie, in honour of Peter's great-grandmother, Lou Beale (Anna Wing).

Max is sentenced to 21 years imprisonment. Max discovers Lauren knew that he was innocent and disowns her. Lauren makes a statement to the Police claiming that Bobby killed Lucy but they do not believe her and she returns to New Zealand with Louie, vowing to come back and clear Max's name.
In May 2016, Bobby puts Jane in a coma and confesses to killing Lucy, so Ian's mother Kathy Sullivan (Gillian Taylforth) telephones Lauren and tells Ian that she and Peter are returning. However, when Lauren arrives with Louie, Ian is surprised to see his stepson Steven Beale (Aaron Sidwell) instead of Peter. Lauren tries to reconcile with an angry Abi, who is furious that Lauren did not tell her that Bobby killed Lucy. Lauren and Steven try to make Ian understand their relationship and why Peter has not returned. When Max is due to have a court hearing following Bobby's confession, Lauren and Abi write a letter saying they will wait for him in the pub, asking Stacey to deliver it. Stacey returns, saying she missed the hearing but passed the letter to his solicitor. Max is released but does not meet Lauren, so she goes home. The letter is returned and she runs outside to see Max leaving in a taxi. Lauren helps Abi get her job back in The Vic and decides to party with her friends. Lauren catches Abi and Lee and assumes that Abi is making a move on him, however Abi drunkenly reveals that she and Lee previously had sex. Lauren promises not to tell Whitney even though Steven tells her to. That same day, Lauren helps Whitney do a pregnancy test, which is positive. Lauren later warns Lee that she knows about his sex with Abi but says she will not say anything because it would mean ruining Whitney's happiness. When Whitney does eventually find out about Lee's unfaithfulness, Lauren supports her. She later starts a business as a web designer, with her first client being Belinda Peacock (Carli Norris). Steven is annoyed when Lauren buys a new laptop following a burglary at the Beales' restaurant. Steven tells Lauren he needed a way to pay debts and she promises not to tell Ian the truth about the burglary as long as they are honest with each other in future.
Lauren is excited when Louie says his first word: "mama". Steven gets him to say "dada" and records a video. Lauren sends it to Peter, which upsets Steven as he sees himself as Louie's father, but Lauren says Peter will always be Louie's father. When Jane discovers Steven has been stealing money from the restaurant, he explains he borrowed it to pay Peter's debts as he is drinking heavily and getting into fights, and Lauren does not know the whole truth. When Lauren learns this, she is angry that he was not honest and considers visiting Peter. Steven says he wanted to protect her and Louie, and going to New Zealand out of guilt or pity will be a mistake, so she decides not to go. Lauren starts to worry that her relationship with Steven has become stale but she does manage to seduce him until they are interrupted. While visiting Max at work, Lauren meets Josh Hemmings (Eddie Eyre) and they share an attraction. Lauren insists on meeting up with him to see what happens. Josh suggests that Lauren apply for a job at the company he works for, Weyland & Co, where Max also works. Lauren is shocked that Josh is one of the interviewers as she thought he worked on the photocopier, so she leaves but Josh follows; she slaps him for lying but they kiss. Meanwhile, Steven is eager for a baby with Lauren but she would rather concentrate on her career, so Steven starts piercing holes in his condoms. Lauren reaches the final two for the job and Max asks Josh not to employ Lauren, and he makes sure someone else gets the job, however, Josh visits Lauren at home and offers her a different job, and he meets Steven and realises Lauren is in a relationship and has a child. Thanks to Abi, Steven becomes paranoid about Lauren and Josh's relationship and starts tracking Lauren's whereabouts via a mobile app. Lauren finds out she is pregnant, and books an appointment to discuss an abortion, soon after revealing her intentions to Abi, as she is not ready to have a second child. Max tells a disbelieving Lauren that Josh is engaged, then Josh admits he is getting married in November. Lauren surprises and annoys Abi by arranging a secret Father's Day visit from Oscar for Max, neglecting to tell Abi about it. However, this drives Abi to reveal the abortion to Steven, though he decides not to confront Lauren. Lauren tells Josh that she loves Steven but admits that there are no "fireworks", and tells Josh that she will not cheat on him, unaware that Steven has been spying on her with a secret camera. Unaware that Abi and Steven have embarked on an affair, Lauren realises she does not love Steven and plans on returning to New Zealand to make amends with Peter. However, Steven learns about her plans and lies to her that he has an inoperable brain tumour. Lauren is wracked with guilt and decides to remain in Walford. In another desperate attempt to keep her, Steven spontaneously proposes to her in the Queen Vic, which she accepts. Lauren then resigns from Weyland & Co and starts planning her and Steven's wedding, however, after a fire which he started at Ian's restaurant, he dies. Lauren is devastated. Abi tries to tell her that she is pregnant with Steven's baby but Lauren misinterprets it as gloating about her own abortion, so Abi says that she wishes Lauren died instead and that she never deserved Steven's love, causing Lauren to start drinking again. On the day of Steven's funeral, Lauren finds out he lied about having a brain tumour and destroys his wreaths. When she finds out that Steven has been cremated, she refuses to scatter his ashes. Abi decides to leave Walford to visit Tanya and when Lauren learns of this, she asks if she and Louie can join her. Abi agrees and they leave Walford together; unbeknownst to Lauren, Abi is secretly taking Steven's ashes with her.
Lauren returns and moves back in with Ian and asks Josh for her job back. Josh accepts and flirts with Lauren but she rejects him again, but after numerous attempts, Lauren eventually gives into temptation and kisses Josh. When Josh's former fiancée, Imogen (Alexandra Sinclair) arrives unexpectedly at the office, she belittles Lauren and tells her that Josh dislikes children. To confirm this, Lauren asks Josh if he would like to spend time with her and Louie; he reluctantly accepts, but implies that they should go as a couple instead which displeases Lauren. Josh later tries to declare his love for her and asks why they cannot be together; she explains that they are different people and that she is a recovering alcoholic. Kathy advises Lauren to move on from Steven and pursue Josh, which she does and they start a relationship. Lauren discovers Weyland & Co's Project Dagmar, a plan to develop Albert Square into luxury apartments, and photographs a scale model. She threatens to publicise the project but her boss James Willmott-Brown (William Boyde), who is also Josh's father, convinces Lauren that the project has fallen through due to investors dropping out at the last minute and she deletes the photo. Josh confirms this, having only just heard about the project. However, it emerges that this was a lie and that Weyland & Co have bought several properties in Albert Square and are evicting business owners. Lauren refuses to give an eviction notice to Ian, so is fired. She discovers that Max is involved in the plan to con the residents. Willmott-Brown destroys Max's contract, revealing that he has also been manipulated, but Josh gives Lauren a copy as he is entitled to his share. Lauren asks Max for the truth or she will destroy the copy, but he destroys it himself, saying that he knew about Abi's affair with Steven and her pregnancy and that his plan was to exact revenge on those who abandoned him. Later, Josh tells Lauren that he can stop the development by revealing that Willmott-Brown bribes members of Walford Council. Josh asks Lauren to stall Willmott-Brown and Fi Browning (Lisa Faulkner) at a press launch so he can get evidence of the bribes, so she chains herself to their property, but is arrested for breach of the peace. Lauren is cautioned and released, and then kisses Josh when he says he has left Weyland, though his plan has failed. Josh is offered a new job in Glasgow and Lauren agrees to move there with him. Ian disapproves of her relationship with Josh when he catches them kissing which causes Lauren to slap Ian, but Kathy convinces him that Josh is not like his father. On Christmas Day, Max gives Lauren a thoughtful Christmas present and she tells him that he needs medical help. Tanya returns to take Lauren and Abi away from Walford, revealing that Max killed Steven and tried to kill Jane. Lauren and Abi reject Max. Max goes to the roof of The Vic where he plans to kill himself by jumping off, but Lauren and Abi climb on to the ledge to try and stop him. As Max agrees to come down, Lauren slips and she and Abi both fall off. They are taken to hospital, where Lauren has surgery on her pelvis, which is fractured, and Abi has a CT scan and is declared brainstem dead. When Lauren starts physiotherapy, she becomes frustrated with not being told the truth about Abi and breaks down when she sees her. Lauren slaps Max for lying to her about Abi's condition and is devastated by Abi's death. Lauren is distraught when Abi's life support is withdrawn.
Before Abi's funeral, Lauren lies to Max that it has already taken place because Tanya does not want him there, however, he realises it is a lie. On the day of the funeral, Lauren tells Whitney about her planned move to Scotland with Josh and Whitney asks her to be sure that she actually loves him or if she is only with him because he is good with Louie. After the service, she sees Max going into the chapel and tells him that she needs to leave, before hugging him and crying. Lauren then takes Louie from Josh and walks away without him. Cora later reveals that Lauren has moved to New Zealand, possibly reuniting with Peter. [11]
Several months later, Ian agrees to babysit Louie while Lauren and Peter patch up their relationship. Shortly afterwards, Kathy calls Ian to tell Lauren and Peter that Bobby is being released from prison. However, Ian tells her that Lauren is refusing to forgive Bobby for ruining her relationship with her dad and causing Abi's death. In February 2020, Jack reveals to Max that Lauren and Peter have split up again and he has been aiding Lauren with money.

Lauren is initially hostile towards Penny when she discovers the truth but eventually forgives her and the two decide to move in together. Lauren and Peter realise they still have feelings for each other. Ian encourages Peter to win Lauren back, while Cindy tells Lauren to only rekindle her relationship with Peter, if she is absolutely sure they will not break up again, for Louie's sake.

Lauren wants to tell Whitney, but Zack begs her not to. Whitney's stepmother and Lauren's cousin Bianca Jackson (Patsy Palmer) finds out and she slaps Lauren for her betrayal. Whitney later falls out with Bianca and asks Lauren to be her maid-of-honour at her wedding to Zack. Lauren is still feeling guilty but she agrees. During Whitney's hen-do, Lauren attempts to tell Whitney that she slept with Zack, but instead says that Zack is not good enough for her, which annoys Whitney. Penny senses tension between Lauren and Whitney, so she deceitfully locks them in a van together. While in the van, Whitney goes into labour and she is rushed to hospital.

She eventually does so and visits Lauren at Ian's café to tell her that she is leaving the Square and that she does not want a feud. And although Lauren is genuinely sorry for her betrayal, Whitney is unable to forgive her and mourns the end of their friendship. After Whitney leaves, Peter assures Lauren that she is not a terrible person and nothing like Max. Lauren then breaks down in Peter's arms and tells him how much she will miss Whitney. When Whitney finally leaves the Square and is applauded by her friends and neighbours, Lauren, along with Zack and Bianca, watches from a distance.
The following week, Lauren is still ostracized by most of the Square for what she did, but she is supported by Peter, who lets her stay with him at his house. She is also antagonized by Cindy, but Peter threatens to move out if his mother can't be civil with Lauren.
