Emmerdale's Cain Dingle and Caleb Miligan could soon be at war all over again, just as the brothers have finally got their relationship on track.
Caleb will commit a major betrayal in upcoming scenes that threatens the livelihood of his brother and Cain's wife Moira Dingle.
Soap boss Jane Hudson has revealed that something Caleb does threatens to send Moira into financial ruin, while she remained coy on the details.
Little is known about what he does and how it affects Moira, but Cain is set to discover his brother has been up to no good it seems.
It's certainly enough to threaten their relationship and tear them apart for good, but what has Caleb done and what does it mean for his family?
Jane teased to The Mirror and other press: "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?"
This isn't the only discovery set to be revealed to the village, as Kim Tate will finally find out her business partner is the mystery heir of her ex-husband Frank Tate.
Asked when Kim will discover Caleb is 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."
Teasing more ahead for Caleb, she added: "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?"
Emmerdale airs weeknights at 7:30pm on ITV1 and ITVX, with an hour-long episode on Thursdays.
