Producer Kate Oates said: "This won't be the first time Emmerdale has broken its 'house style' of storytelling; but it will be the first time we've told a story in a non-linear way. What makes this 'rewind' episode special is that we won't just learn who shot Robert, but two other big secrets that will propel the show into an exciting, emotional and dramatic winter."
Speaking at an Emmerdale press event, Oates said that she is "really pleased" with the fans reaction to the whodunnit storyline that is currently airing.
There are numerous suspects in the frame, including Robert's ex-wife Chrissie Sugden, scorned lover Aaron Livesy and aggrieved brother Andy Sugden.
Oates also teased a "big storyline" in the new year for Aaron and Chas Dingle, who are both currently embroiled in the 'Who shot Robert?' story.
"We have got a big storyline coming up in the new year for Aaron and Chas which will be a new subject for me and for Emmerdale, so I'm looking forward to that. I'm looking forward to crafting the stories that I've got, hopefully leaving the show in good shape for the next guy."
Oates added: "I think it will be a big Christmas for Ashley. There will be some big stuff for the Dingles, it's going to be a very emotional Christmas. It won't be whistles and bangs and stunts. It will all be very heartfelt. I think that's right for us because we had such a stunt-led summer, I think it's good to bring it down to grass roots and to do something that's more emotion and drama based."
