Viewers have recently seen Bart run away with Sinead in a forbidden love plot, but next week's episodes explore how he still has unresolved feelings for Jason. Bart (Jonny Clarke) previously dated the transgender student when Jason first arrived in the village as Jasmine.
The drama begins next Monday when Jason comes to help Bart and Sinead (Stephanie Davis) in their secret location after hearing that they have run out of money and food.
Atkin told Digital Spy of Sinead's unhappiness at seeing Jason: "You'll see them at each other's throats and competing for Bart's attention and love. But what's coming up is really exciting, as you'll also see both characters break down and almost beg each other to let go of Bart.
"Particularly Sinead - there's a really powerful scene where she begs Jason to let Bart go, because otherwise nobody will be able to be with him. Sinead asks Jason whether he really thinks he can make Bart happy. It's quite sad, actually - you'll see both characters really raw. But then they go head-to-head again, and some of those rivalry scenes are really funny."
"I think the story is a great thing to show the audience - it's dealing with how you can't just focus on the outer skin and you've got to look a bit further than that. The story does show that and I think it's lovely. If Bart and Jason really tried, I think it'd be nice to show them just getting on with it and not caring what people think at work, school, college or whatever. I think things could blossom between them - but there'll always be trouble!"
Hollyoaks' Jason, Bart and Sinead storyline plays out next week on Channel 4.
