EastEnders confirmed the return of Roxy Mitchell this week in scenes to air on Thursday night, for a brief cameo.
Rita Simons is reprising the role of Roxy for scenes involving her daughter Amy Mitchell, who is struggling with her mental health.
The news sent fans into meltdown, with viewers having called for the comebacks of Ronnie and Roxy for years after their double exit in 2017.
Roxy and Ronnie were both killed off on the soap six years ago, in horrifying scenes on Ronnie's wedding day to Jack Branning.
But what happened to the sisters and how did they die? What has brought Roxy back, and will it lead to a full-time return? Here's everything you need to know about the twist, and what happened to Ronnie and Roxy.
Who were Ronnie and Roxy Mitchell?
The Mitchell sisters Ronnie and Roxy were the cousin of Phil Mitchell, and nieces to Peggy Mitchell.
They arrived on the Square 2007 and immediately became a hit with viewers, while there were at the centre of huge storylines.
Roxy is the mother of Amy Mitchell, who lives with her father Jack Branning. Jack was Ronnie's partner, while he had a fling with Roxy leading to the birth of her daughter.
Roxy and Ronnie death
R o xy was shockingly killed off in devastating scenes in January 2017, alongside her sister Ronnie.
The deaths sparked a major backlash with viewers who slammed the soap for killing the pair off, instead of leaving the door open for a future return. Ronnie drowned in her wedding dress while trying to save her sister.
Roxy had dived into a pool at Ronnie's wedding venue, but as she hit the water she suffered a heart attack - thought to be a result of her taking drugs.
As Ronnie jumped in she was pulled down by her huge frock, and could not get to Roxy or save herself. The episode ended with the grim sight of their bodies at the top of the water.
Is Roxy returning?
It's all got too much for Amy recently with her losing control again, and in scenes on Thursday night her mother makes an appearance as she looks to her mother once more for help.
Amy wants nothing more than the advice of Roxy and seeks her help in her darkest moments, while knowing nothing will bring her back.
But in surprising scenes Roxy will appear to Amy on Thursday night, just as her family attend a group therapy session.
Amy is encouraged to open up about her emotions surrounding the loss of her mum, and Roxy appears as a figment of her imagination.
While it's in vision form, Roxy is seen on screen in new scenes that were filmed recently with actress Rita.
Speaking about the moment, Executive Producer Chris Clenshaw revealed: "I’m thrilled to welcome the fabulous Rita back to the iconic role of Roxy Mitchell for these special scenes.
"Although the character was last seen on-screen in January 2017, Roxy still remains a fan favourite. We know our audiences will be thrilled at her short return as Amy seeks some all-important answers from her mum at this point in the storyline."
EastEnders airs Mondays to Thursdays at 7:30pm on BBC One and BBC iPlayer.
