Emmerdale fans are convinced they have worked out the "true identity" of Caleb Milligan.
Fans of ITV's Emmerdale have been speculating that Caleb Milligan isn't actually Cain's brother and is really working undercover. Viewers now claim he has secret links to another villager - with some thinking it could be Joe Tate, who left the village after breaking Debbie Dingle's heart.
Twelve years after leaving the village, Joe returned to Emmerdale, using the alias Tom Waterhouse but now fans believe he could have Caleb working undercover for him as he is seen making a mysterious phone call to an unknown caller - although its not be revealed as to why yet.
