For a number of months, Moira Dingle (Natalie J. Robb) has been having a sordid affair with her farmhand Nathan "Nate" Robinson (Jurell Carter) behind Cain Dingle's (Jeff Hordley) back.
Moira's nephew, by marriage, Pete Barton (Anthony Quinlan) uncovered the infidelity and since then the atmosphere between the three at Butlers Farm has been tense to say the least. Faith Dingle (Sally Dexter) was quick to spot the strain and erroneously pointed the finger at Pete for having the affair with Moira.
It wasn't long before Faith told Cain about Moira's affair but wrongly told him it was Pete so Cain packed Moira and Nate away to a farming agricultural exhibition blissfully unaware on what he's actually done.
At Butlers Farm, Cain lured Pete in and eventually knocking him out then tying him to the sofa. Pete tried to keep his knowledge from Cain but in true Cain fashion he always gets his way and it was then the tied Barton let slip about Nate.
With Moira below deck cooking some bacon, Cain began to slowly pick away at Nate, verbally.
Nate twigged Cain knew about the relationship and started poking at the bear by saying how good Moira was in bed. With Cain reaching breaking point it was not long before the veteran Dingle used a blunt instrument on Nate's head knocking Moira's youthful toyboy to the floor. Cain bundled Nate into the living quarters of the yacht then he and Moira had it out.
Moira told Cain everything about when their affair started. With tempers beginning to fray Nate soon comes to and breaks out of below deck.
The two men in Moira's life brawled on the yacht and then it was Nate who revealed the answer to the question that's been on the lips of soap fans for months. Nate called a rather confused Cain, "dad", thus revealing his true identity.
Who is Nate?
Answer: Cain's son.
The how's and the why's will be explained later in the week.
Back in Emmerdale Village at Butlers Farm, Faith got into the caravan where Nate has been staying and started to rummage through Nate's belongings. She discovered his identification documents to realise her own horror about who Nate is.
There's still explosive action to come in this week's Emmerdale but will Cain kill his own flesh and blood?
Emmerdale continues, weekdays, on ITV/STV/UTV.
