Emmerdale viewers were left with more questions on Thursday night, as they learned Nicky Miligan wasn't Caleb Miligan's only child.
Nicky was revealed to be the secret son of Caleb recently on the ITV soap, while no other family member has been mentioned asides Nicky's mum, and of course the Dingles.
Caleb was revealed to be Frank Tate's son last week, and he's out to get revenge on Frank's ex-wife Kim Tate over how she treated his late father.
Kim stole money from Frank after his death and hid assets, while Frank was also the original owner of Home Farm when he lived there with Kim and his children Chris and Zoe.
With Nicky's help, Caleb is keen to get everything he can and leave her with nothing, and on Thursday night fans saw him step up his revenge plan.
But there was a confession by Caleb that left many fans stunned, and wanting answers.
As he continued his secret romance with Leyla Harding, she wanted to know why they couldn't reveal all.
Wanting to go public, she was surprised when he revealed he wasn't ready for people to know and she asked him what he was hiding.
It's then that he claimed he didn't want the news to get back to his kids, revealing he was a father.
But it's the fact he said kids and not kid that left viewers stunned, as it meant he could have more than one child.
Caleb told Leyla he had a "tricky" relationship with his children after splitting up with their mother.
While he might have just been saying it to stop Leyla spilling the beans, the comment appeared to confirm Nicky has one or more siblings.
Viewers have only met Nicky so far and there has been no mention of any other children.
There is at least one more child out there likely of Caleb's, if not more - so will we see them soon, and are they in on the revenge plan?
Taking to Twitter, viewers shared their surprise over the news, with one writing: "CALEB SAID KIDS NICKY ISNT HIS ONLY CHILD WHATTT."
Another tweeted: "so Nicky has a brother? a sister? a brother and a sister? are we about to have a crazy family feud off for the house? Can i be the presenter?"
Emmerdale airs weeknights at 7:30pm on ITV1 and ITVX, with an hour-long episode on Thursdays.
