Emmerdale's Nicky Miligan will spark suspicion with his father Caleb next week, as it becomes clear he's hiding another secret - ahead of him being reunited with someone from his past.
The secret son of Caleb is currently helping him target Kim Tate, with them planning to take everything she has including Home Farm following the reveal Caleb is Frank Tate's son.
Caleb knows that Kim stole money from her ex-husband Frank after he died, and he is also aware of how much they hated each other leading to him plotting revenge.
Nicky is faking a romance with Gabby Thomas, using her to get his hands on her baby son Thomas' inheritance - with Thomas being Kim's grandson.
But the cracks are starting to show with the plan and between the father and son, with Nicky struggling to keep up his act.
Caleb has been putting pressure on Nicky to go along with the romance, with Nicky recently proposing to Gabby and them now planning the wedding.
But after a number of clashes, Caleb might have his work cut out in keeping Nicky on track especially as he causes a scene next week with his uncle Cain Dingle, while Cain has no idea Nicky is his nephew.
Cain knows that Caleb is his brother, but doesn't know Caleb's father is Frank Tate or that Caleb has children.
Next week, Caleb will be forced to confront Nicky over his suspicious behaviour, fearing he will derail his master plan.
That's not all though, as spoilers heavily hint Nicky is hiding something and has another big secret to drop, ahead of a familiar face from his past entering the show.
Spoilers confirm that Nicky goes AWOL, and Caleb is forced to confront him about his disappearing act.
It's then that Nicky admits to being with someone, while the identity of this character remains a secret to viewers and to Caleb.
Nicky then hurries off before Caleb can get any answers, but what is Nicky up to and who is the mystery person he was with?
It's clear he's hiding something from Caleb amid their plan, but it seems he isn't the only one with another secret up their sleeve.
It comes as soap boss Jane Hudson told The Mirror there was more to come from Caleb and Nicky, with more secrets to be revealed.
Teasing more ahead for Caleb, she said: "We have revealed who Nicky is, there is still something else to find out but I'm not going to tell you. Not all the secrets have been revealed yet.
"There is something else we are going to learn and there is going to be someone from Nicky's past who turns up as well and we will be left wondering what this means for Gabby.
"We know they are planning a wedding so is that going to go off? Is it not? Meanwhile, how is Cain going to react when Caleb nearly sends Moira into financial ruin, which is a whole other story that's playing out.
"So when Cain finds out his brother is responsible, how on Earth is it gonna play out when they are trying so hard to have this relationship? Is it all going to be doomed?"
Asked when Kim Tate will find out that Caleb is Frank Tate's son and out for revenge against her, Jane said: "Soon, very, very soon. There is not long to go, it will be after the coronation but before the soap week."
Emmerdale airs weeknights at 7:30pm on ITV1 and ITVX, with an hour-long episode on Thursdays.
