John Partridge is returning to EastEnders in the aftermath of Lucy Beale's murder.
The 42-year-old will reprise his role as Christian Clarke "for a short stint" on the show for the funeral scenes which have just begun shooting.
Viewers will see Christian pay his respects and support his elder sister Jane Beale (Laurie Brett) who was Lucy's stepmother.
It is the first time John has been seen in the show since leaving in November 2012 when Marc Elliott, who played his on-screen partner Syed Masood, decided to quit.
He previously dismissed any possible return, telling Metro: "I'm out of it forever. I didn't get killed or anything. We both left to lead a much better life out of the Square."
Lucy (Hetti Bywater) will be killed off in a whodunnit storyline set to run up until the show's 30th anniversary in February 2015 when the identity of the killer will be revealed.
New pictures released of the funeral, which airs in May, show mourners including her father Ian (Adam Woodyatt), brothers Peter (Ben Hardy) and Bobby (Rory Stroud) and sister Cindy Junior (Mimi Keene) gathering at the church to say their goodbyes.
Since leaving EastEnders, John has returned to his stage roots. He portrayed Zach in the West End revival of A Chorus Line and has been playing the Prince in a pantomime production of Snow White And The Seven Dwarves, a role he will reprise in the 2014/2015 season.
