Caleb Dingle has caused quite a stir since his arrival in Emmerdale as he announced he was Cain and Chas' long lost sibling.
The new arrival - played by Waterloo Road star Will Ash - arrived on Christmas Day, where it was confirmed to viewers that Caleb had come to see his brother Cain in prison, desperate for answers on why his brother had lied to him about their mother Faith. Caleb said that Cain told him their mother had passed away over 30 years ago, when in fact she died recently.
It was later revealed the pair had fallen out after Cain covered for Caleb years back and they decided to end their relationship there.
Now fans of the ITV soap are convinced that the new arrival isn't really Cain and Chas' long lost sibling - and isn't even a Dingle at all, as they rumbled the man's true identity and their connection to another villager.
There has been talk of a number of other men connected to the village, with one being Kerry Wyatt's ex 'Tony' and the father of her two daughters Amy and Chloe, who recently found out they were full siblings.
Whilst Chas has asked for proof that Caleb's who he says he is, fans aren't convinced he really is a Dingle.
"Could Caleb be connected to Chloe or her adopted family?" one fan mused, as another added: "Could Caleb be 'Tony' - Amy and Cloe's dad, Kerry's ex-partner? As Chloe and Kerry are currently absent, it would let him get his metaphorical feet under the table before they return and come face to face with him. @emmerdale."
A third shared: " @emmerdale anyone else think Caleb is Chloe's Dad? Seems far too nice."
"Caleb pretending to be nice but it’s pretty obvious he will turn out to be Chloe’s “gangster” adopted father," a fourth wrote, with a fifth penning: "Why did Caleb deflect the question from Belle about whether he has family and kids? What is he hiding?"
The show bosses teased Caleb's arrival will be "shaking things up" for the Dingles.
Emmerdale producer Laura Shaw previously said: "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!"
