The pair fell in love last year, but stopped short of embarking on a proper relationship as Laurel decided to make a go of things with husband Ashley instead.
Since then, viewers have seen the Thomases hit the rocks once again due to Ashley's abuse of his father Sandy.
This week's TV Times magazine has a summer preview for the soaps, in which actress Charlotte Bellamy discusses where things are heading next for her character Laurel.
Confirming that Laurel and Marlon's plot is far from over, Bellamy commented: "It's inevitable, really. I think they deserve that happiness and it's definitely what viewers want - they keep asking me when it's going to happen.
"Laurel fell in love with Marlon and she only stayed with Ashley because it was the right thing to do. Now her marriage is over, it's time for her to think about what she wants."
Emmerdale fans can expect the story to become prominent on screen again from July.
