EastEnders fans are buzzing with speculation about a shocking Mitchell family twist that

 could shake up the entire Square. The latest theory making waves suggests that the legendary Peggy Mitchell may have had a secret child—and devoted viewers believe they know exactly who it is.

Peggy, played first by Jo Warne and later by the iconic Barbara Windsor, made her debut on

 the soap in 1991 as the fiery matriarch of the Mitchell family. She was introduced as the mother of Phil (Steve McFadden), Grant (Ross Kemp), and Sam (played by both Danniella Westbrook and Kim Medcalf). With her signature brassy blonde curls, bold personality, and unwavering loyalty to her family, Peggy quickly became one of EastEnders’ most beloved and memorable characters.

Over the years, Peggy was at the center of numerous high-stakes storylines. She was the formidable landlady of the Queen Vic, battled breast cancer, endured tumultuous relationships, and fought tooth and nail to keep the Mitchell family together. However, her journey came to a heartbreaking end in 2016 when she made the devastating decision to take her own life following the return of her illness. Barbara Windsor’s departure from the soap marked the end of an era, leaving fans mourning the loss of the Mitchell matriarch.

Despite her absence, Peggy’s influence still looms large over Walford, and now, a new theory suggests that her story might not be entirely over. Fans have taken to social media with a bold prediction—that Peggy had a secret daughter, and that daughter is none other than Nicola Mitchell.

Nicola, played by Laura Doddington, arrived in Albert Square earlier this year as the estranged wife of Teddy Mitchell (Roland Manookian). From the moment she stepped foot in Walford, she made her presence known, immediately stirring up drama. Most recently, she found herself in a tense situation with Sharon Watts (Letitia Dean) after learning that Sharon had once slept with Grant Mitchell, who also happens to be Teddy’s cousin. This revelation has only added to the ongoing tension between them, fueling further speculation about Nicola’s deeper connection to the Mitchells.

Adding to the intrigue, Nicola has also been caught up in a paternity scandal of her own. It was revealed that the father of her son, Barney (Lewis Bridgeman), is not actually Teddy as previously believed, but rather Zack Hudson (James Farrar). The truth about Barney’s parentage came to light after Nicola and Zack’s past affair was exposed. During the March 6 episode, Zack issued an ultimatum, demanding that Nicola tell Barney the truth about his real father before he does it himself.

But as fans continue to dissect Nicola’s growing ties to the Mitchell family, some believe that her connection to Peggy could be the biggest twist yet. In an EastEnders fan group on Facebook, viewers shared their theories, with one excitedly posting: “I would so love if it turned out Nicola was Peggy’s long-lost daughter!” Another fan added: “I’ve said this as soon as she first appeared.” A third chimed in, noting: “They are very similar, and it would definitely be a big twist!”

However, not everyone is convinced that the potential revelation would be entirely positive. One viewer raised an important question about what this could mean for Nicola and Teddy’s relationship. If she were indeed Peggy’s daughter, that would mean Nicola and Teddy are actually related—creating a shocking incest twist that would send shockwaves through the Square. “Wouldn’t that mean Teddy and Nicola are related then? It’s turning into Emmerdale!” another fan joked.

Whether or not the theory proves to be true, the speculation surrounding Nicola and her possible Mitchell lineage has added yet another layer of excitement to EastEnders’ ever-dramatic storytelling. If the writers do decide to explore this twist, it could have massive implications for multiple characters, especially Phil, who has long struggled with the complicated dynamics of his family.

As the drama unfolds, fans will be watching closely to see if Nicola’s past holds any hidden secrets and whether this theory about Peggy’s secret daughter turns out to be reality. One thing is for certain—when it comes to the Mitchell family, surprises are never far away.
