Fans of Emmerdale think they've "worked out" Caleb's really identity after the return of Alex, who they believe he could be related to. Emmerdale viewers had been under the impression Caleb – who arrived in the village on Christmas Day – is Cain Dingle's brother, but now they're not convinced. Caleb has turned his attentions to Kim Tate, who he appears to be intent on bringing down, and fans think a mystery phone call has revealed his true identity.
