James has confronted Moira with the DNA test that proves he is her son's dad, resulting in heightened tension as the long awaited wedding is about to take place."As with any soap wedding there is a few twists and turns along the way," explains actor Jeff Hordley, who plays Cain."There a lot of stuff going on with James and Moira and that's where the drama lies."To begin with Moira is late to the service, held in the family's barn, as she is reeling from James' visit."She's having a bit of a panic attack," admits Natalie J Robb, who plays Moria.But with Cain "totally out of his comfort zone" and left wondering where his bride-to-be is, Moira pulls it together to walk down the aisle. Yet it may not be plain sailing for the couple as guest James still has the power to ruin their special day."It's not power that he particularly wants to wield, but he will wield it if he has to," said actor Bill Ward, who plays James."There is an opportunity in the wedding where he does have the chance to ruin it."With Emmerdale's other wedding, that of Charity and Declan, having its own difficulties, Cain and Moira could also get a day to remember for all the wrong reasons.Emmerdale airs on UTV weekdays from 7pm.
