Sean Slater is a fictional character from the BBC soap opera EastEnders, portrayed by Robert Kazinsky who made his first appearance on 22 August 2006. It was announced in January 2008 that Kazinsky was exiting the show, with scenes concerning Sean's departure airing on 1 January 2009. He returned for a brief stint between 26 April and 6 May 2019, and for one-off appearances on 1 November 2021 and 7 April 2022. In August 2026, it was announced that Kazinsky would reprise the role on a regular basis, with Sean's return to air later that same year.
Creation Sean was created as an addition to the soap's existing Slater family, comprised initially of sister Stacey Slater (Lacey Turner) and mother Jean Slater (Gillian Wright). He was first mentioned on 9 December 2005 when his sister, Stacey, unfolded a family picture to reveal a fourth member (Sean).BBC – EastEnders – Episodes – Stacey admits defeat It was first announced on 13 April 2006 that the character would be joining EastEnders in the coming months, with the revelation made that: "He's going to enter the Square with a bang and will be at the centre of some of the biggest storylines of the year." A month later, on 18 May 2006, it was announced that Robert Kazinsky had been cast in the role of Sean. Kazinsky said of his casting: "I've grown up with EastEnders so I can't quite believe I'll soon be part of the Slater family."
Development Characterisation and relationships Kazinsky has described his character as "a raging psychopath". Explaining in greater detail his understanding of Sean's personality, he has expanded:
Kazinsky has also spoken extensively on several of his character's romantic relationships, declaring in August 2007 that: "Until he knows himself and can forgive himself and actually let his guard down, he's never going to be in a position where he can give to anybody other than himself. At the moment he's a completely selfish, self-serving character." At the time, he speculated that "There's not a single woman who can bring him out of himself, because he's plagued by inner turmoil. Women can have a tempestuous fling with Sean, but they can't ever have love with him, because he doesn't love himself." This idea was expanded on during the character's relationship with Tanya Branning, of which Kazinsky explained: "I don't believe he loves Tanya, I think he's obsessed with her which is a different thing entirely. I think that unconsciously he wants to pay homage to his dad Brian by being the father that he was. And stepping into Max's shoes and taking over his family would have helped him to do that. It's all to do with the guilt he felt over killing his father which is silly really. He didn't stick a knife in him or anything. He hit him and the next day he died of an aneurysm. But as a 16-year-old boy Sean blamed it on himself."
Departure (2008)
In January 2007, Kazinsky was suspended from the show for a period of two months, following allegations he had sent raunchy, inappropriate text messages to a model. The character was temporarily written out of the soap, with a statement released by the BBC which explained: "Following the story in the Sunday People on 7 January 2007, EastEnders executive producer Diederick Santer has taken the decision to suspend Robert Kazinsky from early February for a period of two months. In addition, Robert Kazinsky would like to apologise for any offence caused to EastEnders viewers and for bringing the show into disrepute."
On 18 January 2008, it was announced that the character was to be written out of EastEnders following Kazinsky's decision to quit the soap. The actor said of his decision: "If I had done everything I wanted to do as an actor before I joined EastEnders I would have wanted to stay forever. I have really enjoyed my time with the show – it's such a wonderful place to work and it's become more like a second home to me. I'll be sad to leave." In December 2009, Diederick Santer was asked if anything in the year had not gone as he expected it to. He replied: "[F]or whatever reason, I don't think Sean's exit on New Year's Day was our finest moment. Unusually for EastEnders, we peaked Christmas and New Year with the story and the same bunch of characters and by the time we got to New Year it had rather played out."
Returns In May 2009, Kazinsky revealed that he would return to EastEnders if Roxy was leaving and would be part of her leaving storyline. Talking to Digital Spy he said, "I've always said that whatever happens if Rita ever leaves, I want to be in her exit storyline... I'd love to do that." In 2017, Simons did leave EastEnders, but Kazinsky was not a part of her exit storyline.
On 17 January 2019, it was confirmed that Kazinsky would reprise his role as Sean for a "short stint in the spring", ten years after his exit. Kazinsky's return was previously teased in an interview with senior executive producer Kate Oates that month. In a press release, Kazinsky said that he thought that his "best work was on EastEnders as Sean Slater" because he understood the character and his background well. On his return, the actor commented, "I have unfinished business in Albert Square and am thrilled to be returning to what I still consider to be my home, however briefly." He also looked forward to being involved in his storyline and appearing alongside his on-screen family. Oates praised Sean and Kazinsky, opining that he created "a modern EastEnders icon" through Sean. She confirmed that Kazinsky had involvement in the development of his return story, and added that she looked forward to Sean's return.
Kazinsky made another return for a single episode which was broadcast on 1 November 2021. His return was not announced. Kazinsky later revealed why his return was brief, and expanded on a possible return in the future: "It was simple really, I live in LA and when conditions allow I'll try and see my family every year – or more if I can – so I thought why wouldn't Sean do that. Pop in for a cuppa?" he explained. So I said to Kate [Oates]: 'I'm in London for one day, let's write a scene and I'll swing by in the morning and we can do it, better than that, every time I'm in the UK, if I can, let's do it again' and she rallied the troops and made it happen." He later returned again on 7 April 2022 in an appearance via FaceTime.
Reintroduction (2026) On 17 August 2026, it was announced that Kazinsky would reprise his role on a full-time basis, with Sean set to return later that same year. Teasing the character's comeback, executive producer Ben Wadey expressed his enthusiasm, stating, "Sean Slater was a big part of the Slater family, and as viewers will already know, where Sean goes, drama is not far behind." Kazinsky conveyed his gratitude for the opportunity to return to EastEnders and shared his excitement for the upcoming storylines.
Storylines
Backstory Growing up, Sean adored his father Brian and younger sister Stacey (Lacey Turner), but had a fractured relationship with his mother Jean (Gillian Wright) due to her bipolar disorder. He became rebellious, constantly going out of his way to scare Jean. Sean punched his father during an argument. The next day, Brian suffered a brain haemorrhage and died whilst working on a building site the next day. Believing that he killed his father, Sean panicked and on his sixteenth birthday, he ran away, joined the army and lost all contact with his family. Stacey, aged 11, was left alone to take care of their mother.
2006–2009 Sean Slater first appears in August 2006, seeking revenge on his old friend Al (Andrew McKay) after the latter ended up causing Sean to be kicked out of the Army. Sean breaks into Al's flat and follows him into The Queen Victoria public house, where he ends up seeing his sister Stacey, whom he had lost contact with for seven years. After taking revenge on Al, Sean decides to stay in Walford to look after Stacey. Sean immediately begins pursuing Tanya Branning (Jo Joyner), despite briefly dumping her for Stacey's best-friend Ruby Allen (Louisa Lytton) after learning that she is wealthy. Sean soon begins forging his relationship with Ruby in order to secret exploit control of her financial assets. However, his plan is quickly discovered by Ruby's business partner Jake Moon (Joel Beckett), whom he begins clashing with in the process. Their feud escalates when Ruby confides to Sean that Jake had killed his younger brother Danny (Jake Maskall) to stop him from murdering the "Mitchell brothers", consisting of the square's local hardman Phil Mitchell (Steve McFadden) and his younger brother Grant (Ross Kemp), at the behest of their crime boss and Ruby's father, Johnny Allen (Billy Murray).
Later on, Jake informs Johnny of Sean's plan and subsequently tells Sean that Johnny wishes to meet him in person; Johnny has recently been sentenced to life imprisonment for his criminal activities, specifically for the murders of his gangland rival Andy Hunter (Michael Higgs) and his best-friend Dennis Rickman (Nigel Harman). The next day, Sean visits Johnny and attempts to fabricate his story by proclaiming that his intentions are to create goodwill for Ruby and her future. However, Johnny does not buy it and threatens to have Sean killed unless he leaves Ruby alone. At first Sean appears to feel intimidated, but he then surprises Johnny by taunting him over his real plans for Ruby before leaving prison. This enrages Johnny, who then attempts to have Sean killed by phoning Jake to carry out the order, but he ends up having a heart attack and dies before Ruby can visit him; Jake then leaves Walford after learning about his boss' death. Following Johnny's funeral, Sean proposes marriage to Ruby. They begin to plan out a wedding until Ruby learns of Sean's plan, and Sean also grows irritated when she attempts to help mend his relationship with Jean. Eventually, they split and Ruby leaves Walford afterwards. Sean then continues to pursue Tanya, only to end up having sex with numerous other women – including Karin Jones (Anna Lauren) and Preeti Choraria (Babita Pohoomull).
In 2007, Sean starts dating Chelsea Fox (Tiana Benjamin) and also has sex with her stepsister Carly Wicks (Kellie Shirley), causing a number of arguments. Scorned, Chelsea and Deano Wicks (Matt Di Angelo) try to get revenge on Sean by attempting to frame him for assaulting shopkeeper Patrick Trueman (Rudolph Walker). Sean's attempt to escape arrest fails and he is held on remand. From prison, Sean has Deano attacked so Carly ends the relationship, but discovers that Chelsea has CCTV footage proving that Sean did not attack Patrick. Despite her family's protests, Carly takes the footage to the police. Sean is released, and Deano and Chelsea are arrested for conspiracy to pervert the course of justice. Sean gets revenge on Deano by giving him a bogwash and he also cuts Chelsea's hair.
Sean and Tanya start dating at the beginning of 2008, and Sean tells her that he was responsible for his father's death. In March 2008, they plot to fake Tanya's reconciliation with her estranged husband Max (Jake Wood) in order to gain control of his assets and then leave the country. Tanya pretends to split up with Sean and reunite with Max, but secretly they conspire to bury Max alive. However Tanya feels guilty and releases Max. Much to Sean's surprise, Tanya scorns and rejects him when he says he wants them to be a family and reveals that she used him to get revenge on Max. Sean threatens to tell her children what she has done but Tanya retaliates by threatening to tell Stacey that Sean killed their father. Sean keeps quiet but takes the rejection hard. He then begins to torment his flatmate Gus Smith (Mohammed George). Sean reveals that he plans to kill Gus and make it look like suicide, but Stacey stops him and makes him move back in with the Slaters. Roxy and Sean split up, and Gus reveals to the Slaters that Sean is involved in drugs.
