Jack Branning (
Scott Maslen), purchasing a nightclub,
R&R, together, and begin an on-off relationship. During a period of separation, Roxy becomes
pregnant by Jack after a one-night stand. Ronnie, unaware of who the father is, offers to support her sister and they briefly return to Ibiza. After an argument, Roxy visits their father,
Archie Mitchell (
Larry Lamb), to Ronnie's horror. She is relieved when Roxy returns to the Square but horrified when Peggy announces that she and Archie are engaged. Roxy gives birth to a daughter,
Amy Mitchell, named after the daughter Ronnie had who died. Ronnie is hurt when she learns of Amy's paternity but eventually forgives them both. Ronnie has a tumultuous relationship with employee,
Danielle Jones (
Lauren Crace), eventually leading to Danielle being sacked and Ronnie publicly berating her. Danielle is devastated, and is later seen clutching a locket containing a photograph of Ronnie, revealing herself to be Ronnie's daughter. It transpires that Danielle is the result of a teenage romance between Ronnie and her first boyfriend,
Joel Reynolds (
Cavan Clerkin). Archie disapproved of the pregnancy and put Danielle—named Amy by Ronnie—up for adoption. Danielle was adopted by Lizzie and
Andy Jones (
Aneirin Hughes), and is now trying to locate her birth mother. On Archie and Peggy's wedding day, Danielle tells Ronnie that she is her daughter. Ronnie does not believe her because Archie told her that her daughter is dead, and throws her out. She later realises that Danielle was telling the truth and tries to apologize to Danielle, but she is hit by a car driven by Peggy's ex-stepdaughter
Janine Butcher (
Charlie Brooks) and dies in Ronnie's arms. Danielle's adoptive father, Andy, comes to London to get her and takes Danielle's remains back to Telford and bans Ronnie from the funeral. Despite this, Ronnie goes to Telford and Danielle's best-friend
Stacey Slater (
Lacey Turner) convinces Andy to talk to Ronnie about Danielle. Grieving for the daughter she was not allowed to raise, Ronnie becomes obsessed with having a baby. She tries tricking Jack into getting her pregnant and rekindles her romance with Joel until she learns that he has had a
vasectomy. She gets pregnant by
Owen Turner (
Lee Ross), but miscarries when Archie pushes her into the bar during an argument. Archie is later murdered and Ronnie is arrested as a suspect but released without charge. Ronnie learns that Archie raped Stacey, and Ronnie tells a disbelieving Roxy that he also did the same to her when she was 13. Stacey's late husband
Bradley Branning (
Charlie Clements) is posthumously assumed guilty of the murder after falling from the roof of the Queen Vic while trying to evade police arrest. On Ronnie's birthday, Jack proposes and she accepts. When the issue of Archie raping Ronnie arises again, Peggy refuses to believe it but later learns that Ronnie is telling the truth and that Ronnie and Roxy's mother,
Glenda (
Glynis Barber), knew but did not stop it. Ronnie learns of this and disowns her, though later when Ronnie reveals to a departing Peggy that she is pregnant with Jack's child, Peggy advises Ronnie to give Glenda another chance. Ronnie's cousin
Sam (
Danniella Westbrook) gives birth to a son,
Ricky. She learns that Jack is Richard's father, following a brief relationship. When Sam feels unable to cope with parenthood, they agree that Richard will live with Jack and Ronnie but, having given a child up for adoption, Ronnie can see that Sam is having doubts. Consequently, Ronnie gives her money so she and Richard can leave Walford together. She and Jack marry and prepare for the birth of their child. Ronnie bonds with
Kat Moon (
Jessie Wallace) over being abused as children and have given their first child up for adoption. When Ronnie learns that Stacey killed Archie, she allows her to leave the country after the police are called, feeling that Stacey has suffered enough. With Jack abroad on business, Ronnie gives birth to a boy called
James Branning but he dies of
sudden infant death syndrome within days of being born and as Ronnie seeks help, she swaps her child with Kat's newborn son -
Tommy. Almost instantly, Ronnie regrets her actions. She then tries to swap the babies back, but it is too late as James has been found and Jack has met Tommy upon returning - thinking he is his son. Ronnie struggles to bond with Tommy and refuses to let anyone see him. She is refused permission to attend James's funeral but goes anyway. At the wake, she gives Tommy to Kat but her intention is misunderstood and leads Jack to think she needs psychiatric help. Ronnie discovers that Kat's cousin-in-law
Michael Moon (
Steve John Shepherd) is Tommy's birth father and tries to sabotage his relationships with Roxy and Jack so he will leave Walford but Michael convinces Jack that Ronnie is obsessed with him. Unable to explain her actions, Ronnie agrees that she needs professional help and visits a counsellor but leaves before the session and lies to Jack about it. Glenda realises that Ronnie is not attending counselling but is forced to leave Walford. Ronnie briefly goes missing, and after Jack brings her home, her behaviour becomes increasingly erratic. After visiting the hospital where James was born, she finally admits the truth and returns Tommy to Kat. Questioned at the police station about her mental health, Ronnie admits that she has been having flashbacks since Danielle's death. She is remanded in custody and asks Jack to move on. Roxy convinces Ronnie to apply for bail, which she is granted. Jack forgives her and they resume their relationship. Michael attempts to frame Ronnie for kidnapping Tommy so she will get a custodial sentence. She is sentenced to three years and as she is being taken away, Kat tells her that she forgives her. Ronnie then says goodbye to Roxy, telling her that she was the one looking after her for the last few years. Ronnie sits alone in her cell, holding Danielle's locket, having finally found peace. Jack tries to visit Ronnie but she refuses to see him and in December 2011, she files for divorce.
2013–2017 In September 2013, Roxy, Jack and Kat are notified that Ronnie is being released from prison. Roxy wants to meet her, but Tommy's stepfather
Alfie Moon (
Shane Richie) - who Roxy is now engaged to - protests. Kat goes instead and brings Ronnie back to Albert Square. Alfie insists Ronnie keep her distance, when he finds the sisters reminiscing with Tommy, nearby. As a result, Roxy cuts ties with Ronnie and spends time healing things with Alfie, away from the Square. During this time, Ronnie reconciles with Jack, but when it comes to going public, Jack cannot do it and decides to leave Walford. Ronnie's cousin, Phil, puts Ronnie in charge of his businesses, while he recovers from a car accident. She makes an enemy in
Carl White (
Daniel Coonan), when he attempts to muscle in on the businesses. When Roxy returns to the Square, she and Ronnie make peace but Ronnie becomes suspicious about Alfie's feelings for Kat. She is proved right when he leaves Roxy just after their wedding ceremony. Roxy then starts dating Carl and when Ronnie fails to pull her back together, she convinces Phil to sell The Queen Vic, the pub that Kat and Alfie lease from him, to force them out of Walford. However, Roxy continues to see Carl and Ronnie decides to take Roxy and Amy to Ibiza. When Carl learns about this, he threatens to rape Ronnie and, when he attacks her, she kills him in self-defence by slamming the boot of the car onto his head. She and Roxy then leave for Ibiza, after disposing of the body and only Phil is aware of her actions. When they return, two months later, Ronnie reveals that she has bought the local gym. She learns that
Sharon Rickman (
Letitia Dean) and
Shirley Carter (
Linda Henry) know what happened to Carl and tells Roxy the truth, who accepts Ronnie's explanation of the incident. Carl's family put pressure on Ronnie as they ask about Carl's whereabouts. When they realise that Ronnie has something to do with his disappearance, Carl's brother,
Adam White (Ben Wigzell), snatches
Lola Pearce's (
Danielle Harold) daughter,
Lexi Pearce, while she is in the care of Ronnie and Roxy. Ronnie and Phil track her down and Ronnie hires
Aleks Shirovs (
Kristian Kiehling) to beat Adam up. The following month, Ronnie accidentally runs Lola over, in the same spot where Danielle died. Ronnie is full of remorse for her actions and Lola soon forgives her, realising that Ronnie never intended to harm her. Ronnie has a brief relationship with
Charlie Cotton (
Declan Bennett), the grandson of local gossip
Dot Branning (
June Brown), after confiding to him about her ordeal with Danielle's death. Ronnie and Roxy buy 27 Albert Square, after deciding that Phil's house is too crowded, but after revealing that she is pregnant to Phil, Ronnie decides to leave. Ronnie returns several months later, as requested by Peggy to try to stop Phil and Sharon's wedding, revealing that she is five months pregnant with Charlie's baby. She moves back in with Roxy. Dot, disappointed about the idea of her great-grandchild being born out of wedlock, persuades Charlie to propose to Ronnie. She admits that she has killed a man and, in return, he admits that he is not a police officer and has been lying to Dot about
Nick Cotton's (
John Altman) death. Nick returns to Walford and reveals himself to Dot. Ronnie tells Charlie that she wants him gone. She threatens Nick, saying that he doesn't know what she's capable of. She asks Phil to give her the money stolen from her and Roxy so she can get rid of Nick, but he refuses. Ronnie steals all the money in his safe. On their wedding day, Phil finds out about the money, and agrees to kill Nick. He overhears this and angrily cuts the brakes on Ronnie's car. She goes into labour during the wedding reception, and Roxy and Charlie rush her to hospital, but crash the car in the square due to the cut brakes. Ronnie is rushed to hospital in a critical condition, where her son
Matthew is delivered by an emergency
Caesarean section. She is revived at the last minute, but is placed in a coma for several weeks, before she is finally woken up. After two further months of rehabilitation,
Vincent Hubbard (
Richard Blackwood), a man who it is revealed Ronnie was seeing in the autumn of 2013, visits her. Roxy breaks down and admits that, while she was in her coma, she slept with Charlie in their upsets. Ronnie forgives her and tries to move forward, but has doubts about her marriage. When Vincent's wife
Kim Fox-Hubbard (
Tameka Empson) discovers that Ronnie and Vincent had dated before, she accuses Ronnie of having an affair with him, but she assures her that they are no longer together. On returning home, Ronnie sets up cameras to spy on Charlie and Roxy, paranoid they might sleep together again. Roxy starts a secret relationship with
Dean Wicks (
Matt Di Angelo), and Ronnie is furious when she finds out, as Dean raped
Linda Carter (
Kellie Bright). Dean finds Ronnie's hidden cameras, and Roxy moves out, feeling violated. Ronnie kisses and sleeps with Vincent again, despite them both being married. Ronnie admits she doesn't love Charlie, and ends their marriage. Charlie and Roxy come up with a plan to flee to France with Matthew, but Roxy secretly tells Ronnie and they plan to double cross Charlie and get him arrested. However, events backfire and Ronnie nearly loses Matthew, though Charlie returns to Walford soon after. Ronnie asks Vincent to help her get rid of Charlie, and he disappears, with Roxy finding his discarded wallet. She later asks
Honey Mitchell (
Emma Barton) to move in with her. When Dean becomes increasingly controlling over Roxy, Ronnie asks Linda's help to get rid of him. Linda turns her away, but her fiancé, Dean's brother
Mick Carter (
Danny Dyer), later visits Ronnie and agrees to help her. However, he cannot go through with the plan at the last minute. Dean and Roxy decide to move away, upsetting Ronnie, so she gets Billy to rob his salon. However, Dean realises she was behind it, so proposes to Roxy in front of Ronnie. She tries to pay him off to leave, but he realises she is recording their conversation, so plays it to Roxy at their engagement party. They argue, and Ronnie smashes up the Albert bar, before she tells her relative
Billy Mitchell (
Perry Fenwick) she is going to kill Dean. He warns Mick, and eventually Dean's parents
Buster Briggs (
Karl Howman) and Shirley, who arrive after Ronnie has given him a drink full of crushed up drugs. She reveals it was only a plan to scare him, but it is enough to make Roxy confess to Dean that Ronnie is a murderer, so he convinces Roxy to go to the police. Ronnie is seemingly arrested during a family dinner with the Mitchells. However, Ronnie realises they aren't police, and they drop her off in a wasteland, only for her to be picked up by Vincent. He tells her the police are going to charge her for Carl's murder, and she needs to get out of the country. She decides to confess to the police, but Vincent admits that he is a police informant, and Ronnie agrees to leave. However,
Fatboy (
Ricky Norwood) gives her a file he found in Vincent's safe, revealing he is working to take down the Mitchells. Vincent tries to blackmail her into framing Phil for drug trafficking, using a confession of her admitting to killing Carl. Phil, who has returned to drinking, disowns Ronnie, but she still protects him when Vincent plants a gun on him and calls the police. After, Ronnie destroys the copies of her confession and keeps the gun, threatening to kill Vincent if he threatens her again. Ronnie learns that Vincent is seeking revenge on Phil because Phil's father
Eric (
George Russo) killed Vincent's father Henry. The tensions between the Mitchells and the Hubbards increase when Phil snatches Vincent's infant daughter,
Pearl Fox-Hubbard. Ronnie helps negotiate what she thinks is a truce between the two men, but Fatboy informs her that Vincent is still planning to kill Phil. She organises for men to take Vincent, lock him in the boot of his car and have it crushed. She is distracted when Jack returns to spend Christmas with Amy. When Ronnie sees Vincent and he has no knowledge of the car, she realises the men put someone else in the car boot, but finds it has already been taken to be crushed. After Ronnie tells Vincent what she had planned, he goes to the scrapyard and finds Fatboy is dead. He decides not to tell Ronnie this, and lies that the boot was empty. Ronnie then rekindles her relationship with Jack. She learns from Mick of Dean's attempted rape of Roxy, and Roxy plans to move to Portugal. Glenda returns and tells Ronnie to stop Roxy from leaving but they are unsuccessful when Roxy says Ronnie has controlled her and she needs to be alone. Ronnie re-evaluates her life and, believing that this is the reason why she and Jack are no longer together, asks Jack to leave with Amy as she too needs to be alone. Glenda tells Ronnie that Eric could not have killed Henry and that Vincent's mother,
Claudette Hubbard (
Ellen Thomas), must be lying to him. Ronnie tells Claudette to remain civil towards the Mitchells or she will tell Vincent what she knows. Ronnie later persuades Phil to come to Billy and Honey's engagement party where he coughs up blood and in hospital, the Mitchells are told Phil will be dead within twelve months unless he stops drinking and has a liver transplant. Ronnie then discovers that Joel has died. Ronnie learns that Phil must remain sober for at least six months before he can undergo the liver transplant, so she vows to help him regain his sobriety. She is stunned when Joel's daughter,
Hannah Reynolds (Mia Jenkins), arrives, accusing her of killing Joel. Feeling remorseful, Ronnie tries to give Hannah's uncle
Tim Reynolds (Charlie Baker) a cheque of £5,000 to help look after Hannah and her sisters, but Hannah tears it up. Jack later returns after Honey persuades him to but leaves again after Ronnie tells him they would not be together again. Tim also returns and tries to kiss Ronnie. She decides she still loves Jack, but believing he is getting married, she decides to stop the wedding but when she gets there, Jack is simply a guest at the wedding. Jack and Ronnie have sex but she returns to Walford alone, fearing she will break Jack's heart. However, Jack follows her and says he wants to spend his life with her. Unknown to Ronnie, a stalker leaves a wreath outside her house saying "RIP Ronnie Mitchell". Funeral director
Les Coker (
Roger Sloman) informs Ronnie that someone emailed him that she had died, so Jack wonders who might want revenge on her and Sharon tells him she killed Carl, which angers him until Ronnie says it was self-defence. Ronnie receives flowers with a card reading "RIP", and discovers the person who sent them gave their name as Danielle Jones. Ronnie confronts Hannah, who denies it all and Ronnie believes her, but Jack discovers Hannah's name was on the credit card that paid for the flowers, so Ronnie tells Hannah she knows she sent the flowers. Hannah steps into the road while holding Matthew and is nearly hit by a car. She is arrested for harassing Ronnie. However, Ronnie is still being watched by someone else. Ronnie becomes friends with
Andy Flynn (
Jack Derges), a builder who is helping Jack to renovate Max's old house into flats. Ronnie speaks in Hannah's defence in court and the charges are dropped. Hannah insists that she did not send Ronnie any death threats and she must have another enemy. Ronnie is concerned when Roxy returns, having been beaten up. Ronnie gives Roxy cash to pay off a debt, but Roxy leaves. Andy is then seen looking at newspaper stories about Ronnie that he has collected. Andy is exposed as the stalker but also revealed as Danielle's adoptive brother, Gareth Jones; Ronnie and he make amends after a heart to heart. He remorsefully leaves Walford. Ronnie and Jack get engaged. Ronnie supports Roxy through Dean's trial, comforting her when he is acquitted. Ronnie and Jack decide to move to
Ongar, Essex, to Roxy's displeasure, as Amy would be moving with them. However, Ronnie then suggests that Roxy move to a nearby house in the same town. Roxy suspects that Jack and Honey are having an affair, and tells Ronnie, who confronts Jack. He denies this, and later, Roxy decides Amy should move without her and then asks Ronnie to adopt Amy. After an emotional discussion, Ronnie agrees, but later, the sisters secretly plan for Roxy to join the couple in Essex. However, on her wedding day, Roxy packs her things, as she reveals she is moving away to live with Glenda and Danny, feeling as if she will ruin Ronnie's happiness. After an argument, Ronnie convinces Roxy to give her away, and she agrees. While on the way to the wedding, Ronnie and Roxy visit Phil for a final time and take a picture with him, unbeknownst to him that it will be the last time he sees them. At the wedding, Roxy begins to break down, says she cannot give Ronnie away, and runs out. Ronnie is unable to face Jack and runs off in tears, later revealing she wishes Roxy to move with them, and will not accept any other outcome. Jack eventually accepts, and they marry on New Year's Day 2017, after Roxy gives her away. Later, the two sisters get drunk after a happy day and wander outside the hotel; precariously perched on the hotel roof, still drinking champagne, they discuss their time in the square and the start of a new era. Looking for Ronnie's lost bridal shoe, they accidentally find the hotel swimming pool, and Roxy jumps in. Ronnie is unable to remove her wedding dress, and sees Roxy motionless, having sunk to the bottom of the pool. Ronnie jumps in to rescue her, but is entangled by her wedding dress and drowns alongside her sister just before midnight as Jack reads Cinderella to the children. The following morning, police find their bodies in the pool, and inform Jack's brother
Max Branning (
Jake Wood), who then breaks the news to a devastated Jack. A few days later, Jack receives their wedding video, and watches Ronnie saying how much she loves him; he is emotional watching it. Jack later visits her body in the chapel of rest, a day before her and Roxy's funerals, and says an emotional farewell to her. At the inquest into Ronnie and Roxy's deaths, their deaths are ruled as
misadventure. ==Reception==
