Emmerdale fans are convinced Caleb Dingle will be the centre of a massive affair on the ITV soap.
The long lost brother - played by Will Ash - appeared on Christmas Day, with plans to reconcile with his brother Cain after finding out about his mother Faith's recent death. Cain had lied to Caleb and told him Faith had died years ago. He visited him in prison and Cain warned him not to be in contact with anyone else in the family.
However, he headed to the Dales and revealed all to Chas as well as Cain's wife Moira, who was supported by Mack.
Fans of the ITV soap are now predicting a huge twist - with viewers convinced Caleb will end up having an affair with Moira after spotting a telling sign in a scene during tonight's episode of the ITV show.
One wrote: "Moira, the voice of sanity & reason. Unfortunately, I see a Moira / Caleb affair down the road #Emmerdale," as a second added: "Oh, oh. Did I spy a gleam in Caleb’s eye when he looked into Moira’s eyes as he left? While the cat’s away……… #Emmerdale."
" #emmerdale DO NOT let Caleb have an affair with Moira!!!," a third wrote.
A fourth penned: "Caleb is trying to get into Moira’s knickers #Emmerdale," as another viewer took to Twitter to share their opinion, writing: "So, when does Moira end up in bed with Caleb? #Emmerdale."
Caleb's arrival has already caused quite the chaos for the Dingles - after coming clean to his sister Chas on his identity.
Emmerdale producer Laura Shaw said ahead of Caleb's first scenes: "We are absolutely delighted to welcome Will Ash to the Village. It's fantastic to have such a high calibre and immensely talented actor join our wonderful team. Arriving on screen on Christmas Day, Caleb has to undoubtedly be the most unexpected and shocking Christmas gift Cain and Chas have ever received!
"Calm and in control, rich and successful, at first glance Caleb is everything his brother isn't, but will the pair find they have more in common than they thought? What secrets from the past will come back to haunt them and how will the rest of the family react when Caleb strolls into town? His arrival certainly promises to shake things up for the Dingles and make 2023 start off with a huge bang!"
Emmerdale confirmed Cain and Caleb's back story - and why they fell out - in a flashback episode.
