Emmerdale star Gemma Oaten has admitted she was shocked at her character Rachel's decision to have a fling with Jai.
Rachel Breckle has had her eye on Marlon and David since arriving in the village last year.
However, fans will see her sleep with married factory owner Jai Sharma.
Oaten has admitted that she was surprised when producer Stuart Blackburn told her of the storyline.
She told PA: "When Stuart told me, my jaw just dropped to the floor.
"I didn't see that one coming at all!
"I think I was like the public in thinking it might be Marlon, or it might be David, and then for this to come out it was like what?"
Oaten added: "But it made it more exciting for me, because when you read it on paper you think, 'Is this really feasible? Can this happen?'
"But when we actually filmed it you realise it can happen, it was just two people in the wrong place at the wrong time feeling a mix of emotions and the human body and mind does what it does in those situations."
Discussing the fall out from storyline, Oaten added: "I think she's got a really massive complex about herself and Jai really doesn't help this.
"He doesn't treat her very well and he implies he wouldn't have touched her if he wasn't drunk."
She added: "It rubs salt into the wound for Rachel, because she's down and she doesn't get much affection and love from anybody.
"And to be as close as you can be with another human being and then for him to turn around and treat her the way he does, I think it really hurts and makes her very angry."
