Emmerdale fans are convinced they know who Caleb really is - and why he's so keen to take Kim down.
There has been much talk about who Caleb really is, as some fans of the ITV soap are convinced he isn't really related to Cain Dingle. Fans have also grown concerned after noticing him making a mystery phone call about Cain.
However, viewers are sure they've now cracked who he is and who he actually is related to. After he revealed his plan to bring Kim Tate down, fans think this has sealed his true identity and just why he wants revenge.
As Alex - who has a child with Dawn Taylor - returned to the Dales tonight, fans were left convinced he and Caleb are relatives and that Caleb is keen to see the demise of Kim after she and Will beat Alex up and got him locked up.
One fan suggested: "I think Caleb and Alex are brothers, and that's why he wants revenge on Kim and Will for holding Alex hostage #emmerdale," as another penned on social media: "Alex looks similar to Caleb #emmerdale."
"#Emmerdale fans - could Caleb be Alex’s dad? He’s been on the phone with a mystery person, and Alex is back for a Naomi storyline. Is Caleb taking revenge for what Kim and Will did to Alex? I’m not actually sure of the age of Caleb/Alex," a third shared.
Show boss Jane Hudson previously confirmed Caleb was hiding a secret - but refused to reveal what it actually is.
"I can tell you he’s not an undercover cop. There is a secret about Caleb and viewers have not yet guessed it. I've been reading all the theories about who he is like not that one, not that one," she said earlier this year.
Caleb had made a cryptic phone call to a mystery character, and he mentioned he was reeling someone in to take something from them, as he told them: "We’re finally making headway. We keep reeling him in until we get exactly what we want."
Fans have suggested a number of theories about Caleb's true identity. Some are convinced he is connected to Nicky, the nanny for Gabby's baby as well as somehow linked with the Tates - either Jamie, Joe or Zoe.
Others are sure he must be targeting Kim Tate, as he explained how he didn't want anything getting "in the way of me taking it all and leaving them with nothing" as he set his plan in motion.
