Speaking in an interview with DS, Blyth confirmed that the screen lovers' relationship will continue to hit obstacles as the year progresses, leading up to a big plot which will begin in the autumn.
Teasing the pair's future, Blyth commented: "I don't want to make it a bed of roses for them from the off. There has to be a truth in it. They move forward as a couple but Aaron's journey continues - he'll not readily settle into a romantic situation immediately, he'll be tested and questions asked of him en route as to how he feels as he and Jackson get closer. It wouldn't be true if it was all too easy - and it won't be."
Describing their next main plotline as "one hell of a story", he continued: "It'll be quite something… It starts with an extension of where they are now and is borne out of who Aaron is. He is who he is and he has a temper. He blames those closest to him and pushes them away, even though it's not intentional. He doesn't know when he's on to a good thing… something he may live to regret."
Earlier this year, former Birds Of A Feather star Pauline Quirke was cast in Emmerdale to play Jackson's (Marc Silcock) mother Hazel. Her character is to become involved in the forthcoming storyline.
Blyth also said that he is "delighted" to confirm that Aaron actor Danny Miller will be sticking with the programme for the foreseeable future.
