Emmerdale fans finally discovered Caleb Milligan and Nicky's true identities as the father and son's plan to take Home Farm from Kim Tate was revealed.
Caleb, who was invited to the village when his half-brother Cain Dingle requested his help, is seemingly out for revenge as his father is Frank Tate.
There are many unanswered questions that remain following the reveal concerning Faith Dingle's offspring including the identity of Nicky's mother.
However, one Emmerdale fan has suggested iconic Sadie King, played by Patsy Kensit, could be revealed as the babysitter's mum and return to the village.
Writing in an Emmerdale forum, the Reddit user wrote: "So Caleb is the son of Faith Dingle and Frank Tate, his son is Nicky, whose mother we don’t know yet. My suspicion is that Nicky’s mother is Sadie King.
"Then maybe we can finally have that Kim vs Sadie showdown we were promised back in the early 00s. It’ll also be a cool way to have Nicky be a Dingle, Tate and King."
However, one fan hit back: "It's a great idea but I don't really want to see Patsy Kensit back on the screen tbh, she was bad enough on EastEnders recently."
Meanwhile, Emmerdale viewers have been left reeling over the Caleb and Nicky twist.
One tweeted: "Just catching up on # Emmerdale and I’m curious… does anyone know who Nicky’s mother/Caleb’s wife might be? Or are we supposed to know? There’s a lot of mention of her but we’ve never heard her name."
Another questioned: "Now we know that Nicky and Caleb are related - Who is Nicky's mother? Most importantly what are Caleb's real intentions with Kim?I did not expect that. Nicky is Caleb’s dad and Caleb is a Tate. Let’s hope Caleb brings down the horrible Kim Tate #Emmerdale."
"I'm loving this new side of Nicky. This twist with him & Caleb is going to be a great storyline #Emmerdale," a third said while another added: "Finally caught up on a full week of #Emmerdale All I can say is I never saw this coming All my Caleb and Jamie Tate theories and Nicky, my no idea, just nanny theories were way off."
