Caleb Milligan will catch Nicky out on Emmerdale next week - amid a bombshell DNA twist theory.
Fans have been speculating on what secret Caleb might have after he arrived in the Dales to visit Cain in prison. Caleb and Cain fell out years ago but he returned to quiz his sibling about their mum's Faith recent death.
However, some viewers are convinced all isn't what it seems with Caleb, with some convinced he could be related to the likes of Nicky, the Tates or some are sure he's an undercover police officer. Bosses have confirmed all is not what it seems with Caleb but have so far ruled out just one theory about his identity, with fans suggesting plenty more.
