Mel seduces and stands up to Phil to stop him from pursuing revenge against Hunter.

After Shakil Kazemi (Shaheen Jafargholi) dies from being stabbed, the teenagers spend time at E20 and they later find out money was stolen from the club. Louise breaks up with Hunter after finding out he sent a text reading 'I know what you did' to Louise and the other teenagers.

After Jack feels Mel is too lenient towards Hunter, Hunter is forced to get a job and Ian takes him on to reconcile with Mel; Hunter uses Ian's plan to get away with trouble, however after urging by his friends Ian eventually sacks Hunter for not doing any work.

When Hunter sees Mel being attacked by her new husband Ray Kelly (Sean Mahon), he kills him by shooting Ray dead. When Jack finds out, he tells the police. Hunter confesses to the crime, and is sent to prison. Months later, he escapes. This prompts Mel to keep him from being discovered by letting him stay in an abandoned flat she owns. The pair later plan to escape, but Mel is distracted when Lisa unexpectedly appears and the two discuss their shared plan of fleeing Walford with Hunter and Louise. However, their conversation causes Hunter to seek out Jack on his own – taking Mel's gun with him in the process.

He begins to force Jack to leave with him discreetly, but Hunter is quickly recognised – prompting him to instigate a siege by holding the punters hostage at gunpoint. When Jack attempts to get the gun off Hunter, Hunter ends up shooting Phil's son Ben Mitchell (Max Bowden). By then, Lisa and Mel learn of Hunter's situation and end up becoming his hostages as well – with Mel unsuccessfully pleading with Hunter to stop the siege. Hunter eventually takes a pregnant Louise outside and demands that he is given a car, otherwise he will kill her. When Louise's boyfriend Keanu Taylor (Danny Walters) tries to rescue Louise, Hunter shoots him in response. He then aims the gun at Louise, but she is saved when the police shoot Hunter – killing him. A distraught Mel rushes to her son and cradles him in her arms, mourning the loss of her only child.

On 22 December 2017, executive consultant John Yorke announced a new member of the Slater family would be introduced into EastEnders among the returning Slaters, to "sort Stacey out" after her big 2018 storyline.^[52][53] Hayley's connection to the Slater family was not immediately revealed upon the character's debut, but it was announced that she would be involved in "a brand new mystery" for Martin. Duncan Lindsey, writing for the Metro, suggested that Hayley could be connected to the Slater family, either helping Stacey fight against her estranged husband Martin or a new family member.^[54] The reporter also suggested that Hayley could be acquainted with Martin's former stalker, Sarah Cairns (Alison Pargeter).^[54] It was reported that Hayley would not be friends with Martin, who will have to "watch his back" throughout his custody battle with Stacey.^[54] The character was revealed as Stacey's cousin in her third episode. Of her casting, Jarvis said that she is "really excited to join a team of such lovely, talented people and become part of such an iconic show" and loves being a part of the Slater family, commenting that it is "going to be so much fun and I cannot wait to see what's in store for Hayley."^[55]

It was reported Hayley would have a "horror [...] ordeal" around Halloween as she will be alone as she gives birth, which is described as a "terrifying twist" and leaves Hayley "panic stricken."^[56] Hayley's anxiety also increases under the pressure of keeping the secret about the baby's paternity and her plan to "attempt to do a runner" is stopped when she goes into labour, putting her and her baby in a "worrying situation".^[56] Following the birth, Hayley, described as "struggling" and "overwhelmed", abandons her baby with foster carers Mariam and Arshad, however, her baby suffering a "scare" reportedly makes Hayley "rise to her responsibilities" and "reevaluate her earlier decision to give up her child."^[57][58]

In July 2018, Jarvis was longlisted for the "Best Newcomer", "Best Bad Girl" and "Best Shock Twist" awards at the Inside Soap Awards.^[49] For her portrayal of Hayley, Jarvis was nominated for Best Soap Newcomer at the 2018 Digital Spy Reader Awards; she came in third place with 13.2% of the total votes.^[59] Alfie being revealed as the father of Hayley's baby was nominated for Biggest OMG Soap moment; it came in fifth place with 8.3% of the total votes.^[59]

On 28 March 2019, it was confirmed that Jarvis had left the show and that there were no immediate plans for her to return, though her last episode was on 8 February 2019.^[50]

Magic Marv, played by Steve Steen, appears in the episode broadcast on 20 February 2018.^[60]

Magic Marv is a children's television performer. Tina Carter (Luisa Bradshaw-White) meets him when she is hungover and he reveals the details of the night before when they got drunk and got tattoos of Peter Pan. Tina is shocked by her own behaviour especially as she used to watch Magic Marv on TV when her daughter, Zsa Zsa Carter (Emer Kenny) was a child. Marv then puts on a show at the community centre but he appears drunk and everyone is shocked at how poor his performance is. He calls Stacey Fowler (Lacey Turner) a "yummy mummy" and refers to her as "Sally", insults Martin Fowler (James Bye), and makes comments about Kush Kazemi (Davood Ghadami) being the father of Arthur Fowler (Hunter Bell), who Stacey and Martin have brought to the show. During the interval, Martin finds Marv in the pub and tells him off for drinking and gets angry when he calls Stacey "Sally" again. When the show continues, he gets Kush and Martin on the stage to sing but sends Martin off when he does badly. Marv makes another comment about Stacey and Kush, so Martin knocks Marv's hat off and stamps on one of his drums.^[60]

David Brown of the Radio Times described Magic Marv as "a drunk, shambling mess who insults the dads and ineptly flirts with the mums!"^[61] Laura-Jayne Tyler of Inside Soap disliked the character and felt that Martin and Stacey's reactions to him resembled that of the audience.^[62]

Georgi, played by Holly Donovan,^[63] first appears in the episode broadcast on 20 February 2018.^[64] She is a friend of Zsa Zsa Carter (Emer Kenny), who is Tina Carter's (Luisa Bradshaw-White) daughter.

When pregnant Georgi is in the café, she becomes breathless and Tina helps her. Georgi later meets Tina's sister Shirley Carter (Linda Henry) in The Queen Victoria pub, and Shirley gives her £100 cash and offers to meet her later. When Georgi nearly falls into a table, Tina tries to help her again but Georgi realises she is Zsa Zsa's mother and tells her not to give her any advice as she was a bad mother to Zsa Zsa.^[60] Georgi tells Tina that she does not have a good relationship with her mother and Tina tries to encourage Georgi to reach out to her mother. Georgi is furious that Tina met up with her mother, Tilly (Jacqueline Roberts), and disclosed where she is, which also infuriates Shirley. Georgi goes into labour and despite Georgi rejecting her, Tina helps Georgi give birth to her son and reassures her that she will be a good mother.^[51]

The character of Georgi was announced in February 2018.^[65] It was reported that Georgi is already familiar with Tina's sister Shirley and Tina is "alarmed" that Georgi and Zsa Zsa are friends while Georgi is unhappy that Tina is Zsa Zsa's mother.^[65] It was also said that Georgi's arrival changes Tina's choice to "reevaluate the state of her life", but the "unpleasant surprise" of Zsa Zsa asking Shirley to help Georgi on her behalf forces Tina to "think about the current state of her relationship" with Zsa Zsa.^[66] Tina unintentionally makes thing "a whole lot more complicated" for Georgi when Tina attempts to fix Georgi's relationship with her mother, but gives away Georgi's location.^[66]

Laura-Jayne Tyler of Inside Soap called Georgi a "pregnant Walford waif" and believed that producers originally planned for Zsa Zsa to appear, but when Kenny declined a return, they introduced Georgi.^[62] Tyler questioned why they did not recast Zsa Zsa and felt that Georgi's appearance was "so random".^[62]

Keegan is shocked to see him.^[71] The next day, Mitch flirts with Karen at the launderette where she works and they talk about how Mitch helped raise Keanu but then left when Keegan was born, then later took on her other children but left again five years previously. He insists he has changed and wants to settle down. When Karen brings Mitch home, Keegan, Keanu and their half-sister, Bernadette Taylor (Clair Norris), are against him being there and he leaves when Keegan insists, but Karen later sneaks him into the flat.^[72]

Keanu is angry when he finds out Mitch stayed the night, while Bernadette and Keegan are happy to have him there, and Keanu decides to move out and stay with a friend. Mitch urges Karen to tell Keanu the truth about his own father, but when Karen tries, Keanu walks away. Keegan then overhears Karen and Mitch agreeing not to tell Keanu that his father received a 12-year prison sentence for attempting to kill Karen.^[73] The next day, Keegan mentions that he heard them talking, so Mitch explains what happened. Mitch asks Keegan to convince Keanu to move back home, which he does. While sitting with the family, Mitch receives a text message asking where he is. Mitch agrees to walk the family dog, Bronson, and finds him chewing an envelope of money, which Patrick Trueman (Rudolph Walker) has posted for the Taylors' upstairs neighbours, Ted Murray (Christopher Timothy) and Joyce Murray (Maggie Steed). Mitch says this was his fate and leaves with the money.^[74]

When Keegan is suspended from school for three days, Mitch invites Keegan's headteacher, Mrs Robyn Lund (Polly Highton), to the flat, who gets Keegan to apologise and she reduces his suspension to one day. Karen is annoyed when she hears about Keegan's suspension and Mitch's interference, but Keegan wants them to get along. When Mitch goes to see Karen, he breaks up with his wife over the phone and removes his wedding ring. His wife Marla (Elicia Daly), arrives on Albert Square to see Karen as she wants Mitch back, announcing she is pregnant and both Karen and Marla confront Mitch. When Mitch returns to Marla, she reveals she is not pregnant.

Christopher Riddick from 2004 to 2005.^[67] He said "coming in as Mitch – the wild card – meant I had to hit the ground running."^[67] Mitch shows up at The Arches when his van breaks down, but his "shifty behaviour" makes it clear that his arrival is not a coincidence.^[75] The character left Walford during the episode broadcast on 16 March, but it was confirmed by Sophie Dainty of Digital Spy that he had not made his final appearance.^[76] Mitch returned in the episode broadcast on 26 March,^[77] and departed again in the following episode, broadcast on 27 March.^[68] Laura-Jayne Tyler of Inside Soap liked Mitch, writing, "We think EastEnders is on to a winner with Keegan's charming-but-edgy dad, Mitch. He's very watchable."^[78] On 12 November 2018, it was announced that Griffiths had reprised the role and Mitch would return in late 2018.^[69] Bea Mitchell of Digital Spy billed the return as "dramatic" and reported that Mitch would cause more trouble for the Taylor family.^[69] On his return, Griffiths commented, "It feels great to be returning to Albert Square and working with the wonderful cast and crew again, especially the fantastic Taylor family.

Mick agrees to help Stuart confront a man, but the man is Stuart's friend and they are just testing Mick.

She recalls that "We Call It Acieed" was playing in the car and Stuart must have done it to her.^[113] Tina confronts Stuart but he says it must have been someone else.^[114] Tina decides to tell Mick and Linda but Stuart has already told them, and when Stuart knows that Tina was called a "slag" that night, she again thinks it was him.^[115] She tells Mick and Linda this,^[116] and recalls the football shirt the attacker was wearing, which Mick says Stuart was wearing that day.^[117] Mick confronts Stuart and vows to never see Stuart again, and Stuart stabs an old photograph of Mick.^[118] Stuart then keys his own car and tells people that Tina did it.

After the attack, Stuart seeks revenge on the Carters and unbeknownst to Linda, sneaks into the pub at night, touches Linda in her sleep and records it on video, sending it to Mick. Mick later goes round to Stuart's house and Stuart asks Mick to kill him, goading Mick to attack him when Stuart taunts him about Linda. Later that night, Stuart sneaks into the pub and is shot by an unknown assailant and goes into a coma. His daughter Zara Highway (Faye Daveney) arrives in Walford and claims that one of the Carters shot Stuart. Linda, thinking that Mick has shot him, as he lied about walking Lady Di, then takes the gun and dumps it in the canal to protect him, however she is spotted by Keanu Taylor (Danny Walters). Later, when Mick asks Linda her whereabouts, she tells him she knows but he is adamant he did not do it and Linda worries whether she did the right thing, though Mick reassures her. The next day, Linda is arrested for Stuart's attempted murder as the rest of the square watch on. When Stuart regains consciousness, he states that Mick shot him. Mick is later arrested and imprisoned. When Stuart makes his statement to the police, Stuart picks at his wound with a fork to cause bleeding, which Zara sees, but Stuart insists that Mick shot him; Zara provides Stuart with an alibi on the day Mick went to Stuart's and Stuart wanted Mick to kill him. Upon being discharged, Zara accompanies Stuart to The Vic, where he offers to tell the police that Mick shot him accidentally in exchange for them to accept Mick is guilty and Zara believes Stuart. Zara is lured to The Vic by Halfway in order for Linda to persuade her that Mick is not responsible and she visits Mick, showing her cigarette burns inflicted on her by herself due to having a childhood without Stuart present and wants him to confess. Zara begins to doubt Stuart when Mick tells her that Linda knew Zara's mum by both her and Mick, and eventually walks out on Stuart. Furious, Stuart then hires fellow convicts in prison to help make Mick's life miserable there.

Later, Linda calls time on her marriage to Mick when he admits he started smothering Stuart. She betrays Mick by visiting Stuart, ignoring Mick's desperate phone call and telephoning Stuart saying she believes him. Linda and Stuart begin meeting regularly and become close despite the family's, especially Tina's, protests. She tells the family she thinks Mick is guilty, throws away her wedding rings, and later throws the family out, then allows Stuart to move in, and calls a solicitor to begin divorce proceedings from Mick. What Stuart, Mick and the rest of their family does not know is that all this is a mere smokescreen from Linda to conceal her plan to help get Mick out of prison, which she eventually confesses to her mother-in-law Shirley Carter (Linda Henry) and swears her to secrecy. Linda manages to get Stuart to confess that Mick did not shoot him and he is arrested for perverting the course of justice. Mick bundles Stuart into the boot of a car and drives to an abandoned factory where he vows to kill him.

Ray tells Mel he came because Hunter told him she was in trouble, but Mel says it was a lie. Ray leaves, but Mel later calls him. They meet and talk about their past, and he says he left his job in the police because he made mistakes after she left him and that letting her go was a mistake. She says it is too late and pushes him away when he goes to kiss her, but she then kisses him. Ray spends the night with Mel and makes sure Hunter finds out, and Hunter reveals to Jack that Mel and Ray had sex. Mel tells Jack that Ray is her soulmate and he has changed, but Jack does not believe it and meets a former police colleague to find out anything bad about Ray. Ray does not turn up to a meal and makes calls in secret. After a man, Jeff, calls Ray "Simon", Hunter discovers Ray has passports in the name Simon Wright.

Ray later claims he does not have enough money in his bank account to pay for Mel's engagement ring but she sees a receipt showing a balance of £142,878.04. Ray realises Mel saw his bank balance so tells her that he is saving up to buy E20 for her. Louise Mitchell (Tilly Keeper) develops a crush on Ray when he calls her a "beautiful woman". Ray gets a call and tells Mel he has to deal with a woman named Maddie at the police station. Mel contacts Maddie but Ray is not with her, so they meet and Mel finds out where Ray's regular pub is. Mel goes there and sees him meeting another woman, Jodie (Katie Buchholz). Mel then finds out that Jodie is Ray's daughter and he has another wife, Nicola Kelly (Alexandra Gilbreath). Nicola tells Mel and Maddie that she believes Ray murdered his first wife, Dee, and the three women agree to get revenge on Ray. Ray successfully purchases Phil Mitchell's (Steve McFadden) share of E20 by blackmailing him over his role in the death of Luke Browning (Adam Astill) and the disappearance of Vincent Hubbard (Richard Blackwood). On the day of his wedding to Mel, he talks to her about knowing Nicola, during which she reveals she knows Maddie. He then strangles her to keep her quiet and goes to the wedding. Mel recovers and goes to the wedding, much to Ray's horror. They marry and afterwards, Ray is arrested for bigamy after Nicola and Maddie go to the police. Ray later escapes from the police and attempts once again to strangle Mel to death; however, he is shot and killed by Hunter.

It was first reported on 1 July 2018 that Ray would join the series in the autumn. A show spokesperson said, "Now that Mel is settled after overcoming her initial challenges and has secured a job and built a relationship with Jack, it's time to weave in her first major storyline since her return. And it is a big one—she really shouldn't trust Ray and he will make his presence felt immediately after arriving."^[168] The character and Mahon's casting were officially confirmed on 9 July 2018. It was reported that Ray's arrival would threaten Mel's relationship with Jack.^[167] The character was described as "a serial risk-taker and expert liar" and a source said, "It's safe to say that the residents of Walford shouldn't be fooled by Ray's slick exterior—a man who thrives on danger and who cannot be trusted is lurking underneath".^[167] Mahon said of his casting, "I'm so happy to join such an incredibly hard-working and talented team and I'm very much looking forward to playing out the drama that inevitably ensues on any given day in Albert Square. My character, Ray Kelly is not one to tread lightly and his arrival to the Square will cause shockwaves for many of the residents... it doesn't get much better than that."^[167] Executive consultant John Yorke said, "Sean is both a wonderful actor and a delight to work with. His character brings to the show some very big secrets and we can't wait to watch them explode."^[167]

On Christmas Day, Hayley tells Bev that she wants to move back in with Bev to raise Cherry, but Bev insists that Hayley get Cherry's father involved. When Bev relates how Hayley's father was abusive and violent towards Hayley and her after Hayley was born, the revelation makes Hayley cry. Kat witnesses this and orders Bev to leave so Bev storms out of the house, insulting the entire Slater family.

Bev returns to visit Hayley and Cherry. Hayley tells her to leave, saying she is not welcome, but Bev returns the next day, admitting she was staying with a friend, and apologises for her earlier mistakes. She offers Hayley the chance to move into a potential new flat with her and Cherry, and arranges a flat-viewing later that day. When an exhausted Hayley falls asleep, Bev tries to take Cherry for a walk but Jean returns and accuses Hayley of drinking again when Bev says she is "sleeping it off". Though Hayley and Bev attempt to clear up the confusion, Jean sees sleeping pills that fall out of Bev's bag and accuses Bev of drugging Hayley and trying to sell Cherry again, which Bev denies. Bev tries to assure her her intentions are good but Jean refuses to believe her so Bev points out the times when Jean ignored her family's and Stacey's school's concerns about Stacey as a child, scaring Jean.
