And as they continue to sneak every second together they can spare, it seems the passion between the pair won't be letting up any time soon.
With the farm house full to the brim with people staying, the forbidden couple have struggled to find time alone, and have found themselves on the brink of being caught out a number of times.
But with Moira's husband Cain away, the pair are determined to make the most of their time alone and sneak off to Nate's caravan for an afternoon of passion next week, but they're not as undercover as they think...
Just as they're getting down to business in the caravan, the pair are stunned when Matty almost walks in on them.
Little do they know, Matty is there with Ryan, and they're looking for somewhere to smoke a secret spliff together.
But when Matty fails to get into the caravan, he and Ryan sit outside and smoke their joint - oblivious to that face Moira and Nate are hiding inside, up to no good.
Moira starts to panic as she realises she is trapped inside the caravan the whole time that her son sits outside, and she wonders how on earth she is going to get out of this one.
How will she explain being inside Nate's caravan alone with her farmhand in the middle of the day?
After hiding in the caravan for what feels like an eternity, Moira spots a moment when Matty's back is turned and she makes a run for it.
But just when she thinks she might have got away with it, she comes face-to-face with a lumbering Matty... but will he realise what he has just stumbled across?
With Cain's return to the village imminent, could Moira's dark secret be exposed?
