Emmerdale fans were left stunned when the soap revealed that Mackenzie Boyd (Lawrence Robb) had survived his brutal encounter with John Sugden (Oliver Farnworth). Just last week, viewers were convinced Mack had been killed after discovering John’s murderous secret.

Mack had pieced together that John was behind Nate Robinson’s death and disposal. The confrontation spiraled out of control when John shot Mack with a crossbow and appeared to finish him with a rock. For many, this looked like the end of Mackenzie’s story.

However, Monday’s episode (September 1) delivered the shocking twist — Mackenzie is alive, but trapped in an underground bunker hidden deep in the woods.

A Chilling Encounter with John

In his first moments awake, Mack demanded answers from his captor. John, perhaps relishing the power he held, started to open up about his crimes. Mack then tried to strike a deal, promising to leave for Scotland and never reveal what he had learned.

For a fleeting second, John seemed to waver. But the moment Mack attempted to attack him, John’s darker instincts resurfaced. He made it brutally clear that Mack would never be walking free.

This revelation has shifted the storyline into even darker territory. Yet, fans believe the bunker is hiding more than one terrifying secret.

Fan Theory: Another Body in the Bunker

The biggest theory circulating among viewers is that Mack isn’t alone underground. Fans are convinced that Anthony Fox’s body could also be buried there.

Long-time viewers will remember Anthony (Nicholas Day), who was killed by his daughter Ruby Miligan-Fox (Beth Cordingly) after years of abuse. John then stepped in to help Ruby cover up the crime by disposing of Anthony’s body.

What has always remained a mystery is where John put the remains. Now, with Mack being held in a secret bunker, fans are drawing connections and suggesting this is where Anthony was hidden all along.

Viewer Reactions and Speculation

Social media has exploded with theories. On a popular Emmerdale fan page, one viewer declared:

“100% Anthony’s down there with Mack.”

Another wrote:

“Yep, probably has his body stored there!”

A third fan speculated further:

“I thought that and maybe other bodies.”

Others are questioning whether this storyline is setting up an even bigger discovery. Could John’s bunker be hiding multiple victims?

What This Means for Mackenzie

If fans are right, Mack’s imprisonment could soon uncover a graveyard of John’s past crimes. That would make Mack’s survival even more dangerous — not only does he know John’s darkest secrets, but he could also expose Ruby’s role in Anthony’s death.

The stakes are sky-high for Mack. His only chance of survival may be to outwit John, but the odds are stacked against him. Meanwhile, Charity Dingle still believes Mack is in London, completely unaware of the horror unfolding nearby.

What Happens Next?

Emmerdale thrives on twists, and this storyline is shaping up to be one of the most chilling yet. Will Mack find an escape route before it’s too late? Is Anthony Fox really buried in the bunker, or could there be an even bigger shock in store?

Fans will have to keep watching as John’s twisted secrets unravel and the danger for Mack intensifies. One thing is certain — Emmerdale viewers are in for a tense, nail-biting ride in the weeks ahead.
