Scenes will show the opening day of Hawkford Outdoor Pursuits and Marlon has been enlisted to help Kim Tate (Claire King) with providing the catering.
However, as he starts unpacking the food van and preparing the produce, Rhona arrives unannounced.
She explains how she needs Marlon to look after Leo, and how it would be a good opportunity for the father and son to spend quality time together.
What Marlon doesn’t realise is how Rhona needs to time to sort out the final preparations, as she and Graham plan to move to France the next day.
But Rhona’s conscience starts to get the better of her and she decides she needs to tell Marlon the truth.
