NOW that Nate Robinson has finally revealed he is Cain Dingle's son, Emmerdale viewers are frantically trying to uncover the identity of the farmhand's mum.
Nate dropped the bombshell on Cain as they brawled aboard a boat, after the Dales hardman discovered his wife Moira was having an affair.
Fans of the show were delighted to finally know Nate's secret, but with the reveal came another identity mystery - if Cain is Nate's dad, who is his mum?
They flocked to Twitter to share their theories and there are a few names that keep cropping up.
One unlikely choice is Faith Dingle - Cain's mum - which would actually make Cain Nate's brother, not his son.
Some viewers put her name forward after noticing her strange facial expression inside the caravan where Moira and Nate romped.
Faith pulled a shocked expression when she saw a photo in Nate's possessions - indicating that it could be HER who is Nate's real mother.
One viewer wrote on Twitter: "I have this strong feeling that Faith is Nate's mum ... by the look on her face. #Emmerdale."
As another said: "Nate will not actually be Cain’s son!!! Come on, it’s far too predictable and obvious.
"He might believe Cain is his dad but he won’t be. Faith is his mum, that’s why she looked so horrified in the caravan, she found something #Emmerdale."
Some fans are convinced Nate’s mum’s name is ‘Cara’ after ‘leaked audition tape’ surfaced online - before promptly being taken down.
Another name floating around is Cain's ex, policewoman Angie Reynolds.
However, she died in Cain's arms in the early noughties after a high speed car chase, effectively shutting down that plot line - unless Nate is aging extremely well and is secretly in his thirties.
Latisha Daggert has also been mentioned, with one tweeter posting: "Hang on, could Nate's mum be Latisha Daggert?? 🤔🤔 #emmerdale."
The bad girl had a relationship with Cain around the same time as his fling with Angie.
The pair were involved in a string of petty crimes, including stealing Charity's Dingle's credit card.
Their relationship ended when Latisha found out Cain still had feelings for Angie.
She went to Lisbon with friend Jason Kirk to start a new life.
Of course, it could be someone new altogether who fans of the show have never seen onscreen - a mystery ex of Cain's about to come back and ruin his life.
One eagle-eyed viewer spotted a picture in Nate's hand they believed to be his mum, however, they couldn't make out the identity.
They posted: "Who could Nate's Mum be in #Emmerdale? Don't recognise her from the glimpse of her photo. 🤔."
Could a brand new character be about to join the show?
Last night Moira was sent flying into the water to her possible death, after Nate's big reveal.
Viewers were horrified that he'd knowingly had sex with his step-mum, tweeting: "I've just realised.. if Cain is Nate's dad, then he's technically been s**gging his own stepmum...🤢"
Gripping scenes saw Cain and Nate grappling on the deck of a small yacht after the older man forced him and Moira to join him on a fishing trip.
While Moira was below deck, Cain seethed: "Some women, they read magazines, watch reality TV, that kind of thing. Moira does sex.
"She says it's the only thing that stops her thinking. So when it comes to blokes, she doesn't really make the best choices."
Nate replied: "Your missus is bored of your boring life and your boring marriage. That's why he's going behind your back with me.
"In the caravan, the barn, in your bed while you were in Scotland. Last night, all night. The sex was the best she's ever had, obviously."
After that, Cain grabbed a plank and knocked him out cold - but he later came round, bursting onto the deck roaring: "You're pathetic, old man."
Putting his face close to Cain's, he growled: "Nate. Short for Nathaniel. Look at me and remember.
"You see me now - Dad? You must have known that I'd come for you one day. I'm your son."
Moira, apparently believing some kind of practical joke was taking place, lectured him: "If you think this is funny, it's hardly the time."
But Nate snapped: "Stay out of it. Your use is over."
Cain, steadying himself onto the boat and looking utterly bewildered, was jolted back to reality when Moira was sent flying into the water.
