Charity Dingle (played by Emma Atkins) is set to come face-to-face with her estranged son after it was revealed the child she had as a teenager had actually survived.
The mother-of-four has struggled with her past on Emmerdale in recent weeks, as the truth was revealed about her abuse at the hands of police officer DI Mark Balls (Rocky Marshal).
In an upcoming episode, Charity’s 27-year-old son Ryan Stocks (James Moore) will arrive in the village to meet her for the very first time.
She will learn her son has Ataxic Cerebral Palsy and will find it hard to cope with the guilt of abandoning him all those years ago.
With so much lost time, will Ryan forgive his biological mum for leaving him?
Also, will Charity learn to forgive herself for being absent in his life?
Emmerdale producer Kate Brooks promised Ryan’s arrival would throw a ”spanner in the works” and teased “unexpected twists” to come.
“We are absolutely delighted to welcome James to the show; an actor of real skill, talent and charisma,” she said.
“As to be expected with his Dingle heritage, the character of Ryan is feisty, funny and reckless, and with an unquenchable zest for life.”
She added: “Ryan will not only turn Charity’s life upside down, but also the wider Dingle clan as his arrival throws a massive spanner in the works.
“As Ryan navigates his newfound family ties and connects with the mother he never knew he had, it unearths yet another layer to Charity.”
Meanwhile, James said: “I’m so excited to have joined the Emmerdale cast. Everyone is so welcoming and friendly and I’m having a great time playing Ryan.
“I leapt a mile when I got the call and I was over the moon to hear that I had got the part.”
Elsewhere, Emma spoke about her character’s latest storyline and the shock discovery that her child survived.
“I think the fact she was convinced that this child never survived, the shock impact will be huge, and the audience will clearly be waiting for that moment,” she shared with What’s On TV.
“It is a big moment in her life, to discover her child did actually survive.
“What would anyone think? You just have to be human to know that would knock anyone west.”
Sharing her excitement at the possibility of the Dingle clan expanding, she offered: “It’s an amazing idea; I got chills.
“There’s an episode when Charity’s face to face with her past in some shape or form, and it’s remarkable.”
Emmerdale continues tomorrow at 7pm on ITV.
