Amy Mitchell

For the first few weeks of her life, she is raised as the daughter of Roxy's husband Sean Slater (Robert Kazinsky) and was briefly given his surname, as he and Jack are unaware of Amy's true paternity. Amy is born two months premature and is put on a ventilator from birth. She is named after the daughter of Roxy's sister Ronnie Mitchell (Samantha Janus), whom she put up for adoption many years ago. Roxy initially decides to raise Amy with her friend Christian Clarke (John Partridge), after Sean misses Amy's birth but changes her mind when she and Sean reconcile.

Jack asks Roxy for a paternity test, aware that Amy may be his daughter. It transpires that this is so on Christmas Day 2008, when Suzy Branning (Maggie O'Neill) gives Sean the results as a present, which leads to Sean abducting Amy. There is a fierce argument when Sean is found with Amy, which leads to Sean leaving and Amy is returned to Roxy by Sean's sister Stacey Slater (Lacey Turner) on New Year's Day. Jack then spends more time with Amy and Ronnie decides Amy should be Christened and Roxy agrees. Amy's godfather is Christian and her godmother is her step-grandmother Dot Branning (June Brown), although Ronnie is originally meant to be her godmother, but gets drunk and turns up late to the ceremony.[6] Christian and his partner Syed Masood (Marc Elliott) look after Amy for a day and decide that they want a child. While Amy is being looked after by Ronnie, she draws a picture, which upsets Ronnie has Ronnie interprets it as including her son who died. Amy escapes from the house, which leads to everyone discovering Ronnie has been bailed from prison after swapping her dead baby James with Kat Moon's (Jessie Wallace) healthy son Tommy. Amy also escapes when Roxy's boyfriend Michael Moon (Steve John Shepherd) leaves the door open. Amy is almost hit by Carol Jackson's (Lindsey Coulson) car but is saved by Eddie Moon (David Essex). When Amy suffers a fall at home, Roxy thinks nothing of it. Roxy goes on a night out with friends, leaving Ben Mitchell (Joshua Pascoe) babysitting Amy. When he leaves Amy alone for a while to get a DVD from Jack's flat with Jay Brown (Jamie Borthwick), Amy runs herself a bath, gets in and almost drowns. When Ben discovers her, Dr. Yusef Khan (Ace Bhatti) is called and he revives her. Amy is taken to hospital in a critical condition. She recovers, but she is found to have a fracture from her previous fall, so a social worker awards temporary custody of Amy to Jack. Roxy later is allowed to see Amy, whilst a social worker evaluates Roxy's parenting skills. Jack refuses to allow Roxy to see Amy other than at arranged times. A solicitor tells Roxy to dig up as much dirt on Jack and his family as she can, but this does not work as a court grants full custody to Jack. When Roxy's cousin Phil Mitchell (Steve McFadden) has Jack's car crushed, Jack tells Roxy she cannot see Amy until it is replaced. Jack does not allow Roxy to give Amy her gift at Christmas, so Roxy shows Amy her puppet toy through the window, meaning Jack is forced to let Amy see Roxy. Amy starts scratching other children at nursery because of the tension between Roxy and Jack. Eventually, Roxy wins her custody case, though Jack reveals he dropped it because Roxy threatened to report him for fraud, as he forged her signature to get Amy a passport. When Roxy catches head lice, she blames Bianca Butcher's (Patsy Palmer) children, but she finds out she actually caught them from Amy. Amy's father, Jack moves away in October 2013, and Amy lived full-time with Roxy and her fiancé, Alfie Moon (Shane Ritchie) until the couple separate on their wedding day in November 2013.

On New Year's Day 2014, Amy, Roxy and Ronnie move to Ibiza for an extended break. She returned to Walford a couple of months later with Roxy and Ronnie now played by Abbie Knowles. Amy has a strong personality and can often be quite naughty. In 2015, Roxy reveals that she arranges monthly trips for Amy to go to France to visit Jack. During Christmas, Jack returns to Walford to visit Roxy and Amy, and upon finding out that Roxy's fiancé Dean Wicks (Matt Di Angelo) raped Linda Carter (Kellie Bright), he packs Amy's bags and sends her to Ronnie's house, scolding Roxy for letting Dean control her.

Roxy leaves Amy with Jack in January 2016 after Dean tries to rape her. Jack and Amy temporarily leave Walford but return when Jack decides to move back to the square permanently so he can be with Ronnie. Roxy returns to Walford but when Jack finds out Roxy agreed to be a drug mule and smuggled £10,000 of cocaine into the country, he is reluctant to let Roxy see Amy. Eventually, Ronnie persuades him to let Amy stay in Roxy's flat overnight but while Jay and Roxy argue over the drugs, Amy finds them and her rabbit Hercules dies after eating cocaine. Amy runs away but is soon found by Andy Flynn (Jack Derges). Jack worries that Amy may have taken drugs so takes her to hospital. Amy is fine but upon realising Social Services are going to be involved, Jack threatens to go for full custody of Amy. However he drops the case when he realises how much Roxy has suffered after Dean attacked her.

Roxy begins to feel distant from Amy and tries to do things right for her, deciding she wants Ronnie to adopt Amy. Ronnie reluctantly agrees. On Jack and Ronnie's wedding night, both Ronnie and Roxy drown and die in the hotel swimming pool. Jack does not want Amy to know but she asks questions about their whereabouts, so he confuses her by saying they have "gone away" and will never return. Amy and her half-brother Ricky (Henri Charles) continue to question Jack, so Dot explains to them with sensitivity that they have gone to heaven. Ronnie and Roxy's mother and Amy's maternal grandmother, Glenda Mitchell (Glynis Barber) returns to Walford and convinces Jack not let Amy and Ricky attend their funerals, but he later changes his mind. Jack allows Glenda to move in to help raise Amy, Ricky and Ronnie's young son, Matthew Mitchell Cotton. Jack and Glenda talk to Amy when they find out she has been wetting the bed over Ronnie and Roxy's deaths. When Glenda has Amy's ears pierced like Roxy's, Jack throws Glenda out because he does not want Amy to see Roxy as a role model. Jack hires Ingrid Solberg (Pernille Broch) as an au pair and she fails to connect with Amy and Ricky by preparing a Norwegian meal, but they bond over pizza. At Halloween, Amy, her cousin Janet Mitchell (Grace) and neighbour Riley Taylor (Tom Jacobs) go missing and when a child is hit by Tina Carter's (Luisa Bradshaw-White) car, Jack fears that is it is Amy. The child is revealed to be Janet. Amy is later found with Kim Fox-Hubbard (Tameka Empson).

Amy later befriends Lily Slater (Lillia Turner), Denzel Danes (Jaden Ladega) and Davinder "Nugget" Gulati (Juhaim Rasul Choudhury). Lily steals ecstasy pills and shows them to her friends in the park. Amy suggested that she would take them, as everyone else was scared to, and she later ends up in hospital. Due to this, Jack bans her from being friends with Denzel, as they believe he was the one that stolen the pills as he is related to Denise Fox (Diane Parish) who owns the salon. This is later to be revealed as Lily is the actual culprit and Denzel and Amy start a relationship.

Amy later starts self harming as she can’t cope with coming to terms with her mothers death,[3] [4] the increasing household issues going on as Jack and Denise are constantly arguing due to her affair with Ravi Gulati (Aaron Thiara). One night, she is left home alone with Ricky as Jack and Denise are on a date and she has cut too far and is gushing with blood, and Ricky calls an ambulance and she is taken to Hospital.[3]

Robert Kazinsky who plays Sean Slater teased the Christmas storyline saying, "Sean ultimately deceives Roxy and snatches baby Amy from The Vic. Then there's a whole week of the Mitchells trying to track Sean and Amy down. Sean's holed up in a squat with the baby to give them more time together. He's simply looking after Amy, who's become the most important person in his life. Even if she isn't his child, mentally and emotionally, she is to Sean. Eventually, Sean's found and it all kicks off, culminating in a stunt with an icy lake…"[7] Kazinsky said that he thinks Sean would be a good dad to Amy saying, Sean was 16 when his father died, so for Sean, bringing up baby Amy was a way for him to make it up to his dad – by being the father to Amy that his father was to him."[7]

Amy was made regular in the episode first broadcast on 9 August 2022. She is later in a storyline dealing with self harm.[3]
