Emmerdale viewers believe they've worked out who Caleb "Dingle" really is.
The show recently travelled back in time to portray exactly how and why the lost Dingle has been missing for so long. During the Christmas special, it was shown that Caleb was born in prison and shortly put into care which explained why he's been missing from his brother Cain's life for so long.
Cain has always known about his brother but kept him a secret from the village, including his own sister, Chas. Making his grand return to everyone's life, Caleb's time in Emmerdale has been relatively uneventful despite Cain angry and not willing to trust his motives.
