John Sugden, played by Oliver Farnworth, has been a source of intrigue since his arrival in
Emmerdale last year.

While he initially appeared to be reconnecting with his half-sister Victoria Sugden (Isabelle Hodgins)
and forming a relationship with Aaron Dingle (Danny Miller), fans have started to suspect there’s more to his story than meets the eye.
The mystery surrounding John has intensified, with many viewers convinced he is connected to the unidentified body recently discovered in the lake.

Some even believe they’ve uncovered a vital clue that links him to the crime.

Is John Responsible for Nate Robinson’s Disappearance?

Speculation about John’s true nature escalated when eagle-eyed fans noticed a crucial detail—the body found in the lake was wearing a bracelet identical to the one Nate Robinson’s daughter, Frankie, had made for him.
Nate, a former villager, left the Dales last year, and his sudden disappearance has fueled theories that he may have met a grim fate. The discovery of the bracelet has led many to believe that Nate is, in fact, the victim, and John may have had a hand in his demise.
Adding to the suspicions, fans recalled a similar tarpaulin being used when John helped dispose of Anthony Fox’s body. Some viewers believe this points to a pattern of behavior, suggesting John could be more dangerous than he lets on.
A Web of Secrets and Deception
John has already been involved in covering up a major crime. When Anthony Fox was killed, many initially believed Aaron had committed the murder. In reality, it was Anthony’s own daughter, Ruby, who took his life after suffering years of abuse.

Despite not being the killer, John played a key role in covering up the crime, further casting doubt on his morality. With his willingness to conceal the truth, it’s no surprise that fans are questioning whether he’s hiding something even darker.
Fans Speculate John Is a Serial Killer
The theory that John could be responsible for Nate’s death has taken a chilling turn, with some viewers going as far as to suggest he might be a serial killer.
One fan pointed out on social media: “Okay, anyone thinking John had something to do with Nate? That tarp wrapping has got me thinking. Might have to go back and watch to see if I can spot the connection.”
Another added: “It was John. He’s not who he says he is and is a serial killer.”

If these suspicions prove correct, it would mark one of the most shocking twists in Emmerdale’s recent history, turning John from a seemingly troubled newcomer into a dangerous predator.
A Controlling Side Emerges in His Relationship with Aaron
As the mystery surrounding John deepens, fans have also begun to express concerns over his relationship with Aaron. While their romance initially seemed passionate, some have noted unsettling signs of control and manipulation.
One viewer highlighted a particular moment that raised red flags: “I thought you loved me’ was a huge red flag.”
Another commented: “That ship sailed when he told Aaron to shut up when he was venting about Anthony and getting caught.”
Others have described John’s behavior as “manipulative, secretive, controlling, and proper creepy,” hinting that Aaron may find himself in a dangerous situation.

What’s Next for John and Aaron?
If fan theories hold any weight, John’s storyline could be heading toward a dramatic and tragic conclusion. Whether he is truly responsible for Nate’s disappearance or simply hiding another dark secret, it’s clear that his presence in the village is becoming more unsettling by the day.
Aaron, having already been through immense personal turmoil, could find himself in serious trouble if he remains entangled with John. If the suspicions of control and manipulation continue to grow, he may need to escape before he becomes another victim in John’s tangled web of secrets.
As Emmerdale continues to unfold, viewers will be keeping a close eye on John Sugden, waiting to see if their darkest predictions come true.
