In the latest EastEnders twist, on-the-run character Ryan Malloy (Neil McDermott) was seen in Walford in Tuesday night's episode on BBC One and RTÉ One.
Whitney Dean (Shona McGarty) had gone to meet her brother but left believing he had stood her up.
However, the camera then moved to show Ryan watching from a distance.
Writing on Twitter about his return, actor McDermott said that the show's executive producer, Dominic Treadwell-Collins, is "giving Cilla [Black] a run for her money with his surprises! And will keep them coming."
Thanks for the lovely reaction to tonight's Eastenders. It's great to know the character is remembered so fondly. Have a lovely night y'all!
