Emmerdale viewers shared a new theory about Caleb and Ruby Miligan’s mystery daughter Stephanie amid predictions she will soon debut on the ITV soap

Emmerdale viewers are convinced Caleb and Ruby Miligan’s mystery daughter Stephanie could be involved in a big Christmas Day twist.

Tuesday night saw the reveal that Caleb and Ruby had a daughter named Stephanie, with it hinted they were not in contact. We’ve never met Nicky Miligan’s sibling, and they have never really been mentioned.

While in the past there have been hints of Caleb having more than one child nothing had been confirmed and no name was given until now. Ruby’s mother Helen asked Caleb if he “saw anything of” his daughter, leading to him getting defensive and shutting her down.

It’s then that he screamed: “Don’t you dare say my kids’ names,” confirming he did in fact have another child. It’s thought Stephanie is the child of both Caleb and Ruby, but it isn’t known who she is or if she will arrive in the village.

We also do not know what led to a possible estrangement between them, given Stephanie is never talked about and Helen’s comment hinted there was a distance between them. Ruby’s mother Helen made her debut on Tuesday in a showdown with Caleb, while she and daughter Ruby have been estranged from for years.

We learned more about what led to Ruby being separated for her family, after previous hints they did not approve of Caleb. Caleb revealed Ruby had fallen pregnant and that Helen and her husband tried to force Ruby to have an abortion.

When Ruby refused, Helen and Ruby’s father disowned her and kicked her out, sending her packing. Ruby and Caleb began their new lives together welcoming their baby, before going on to have a second child.

Viewers now believe Stephanie will head to the village after hints Caleb and Ruby could face a shock. Amid a “Christmas arrival” yet to be detailed, viewers think it could be their estranged daughter.

One fan posted: “I think they have a daughter and she might be making an appearance.” Another said: “Caleb and Ruby are expecting a shock arrival (I don’t know when) so I wonder if it’s that person. Maybe it’s the once mentioned sister of Nicky that was never mentioned again. Or maybe one of Ruby’s relatives, I know she grew up in care home but so did Caleb and he has relatives, has Ruby mentioned any?”

Emmerdale airs weeknights at 7:30pm on ITV1 and ITVX, with an hour-long episode on Thursdays.
