Emmerdale viewers have "rumbled" Caleb Milligan's affair twist.
The long-running soap has been rocked with drama since Cain and Chas Dingle's long lost brother arrived in the fictional Yorkshire village. A flashback episode on Boxing Day explored the origins of Cain and Caleb's relationship - and why his identity has been kept secret until this point.
Cain is currently behind bars after he pleaded guilty to the murder of Al Chapman. The character, played by Jeff Hordley, has confessed to the crime to protect his son, Kyle, who is the real killer - as Mirror Online reports.
