An Emmerdale trailer has been released that shows the moment Mackenzie Boyd (Lawrence Robb) learns the truth about John Sugden (Oliver Farnworth).

Mackenzie was suspicious of John for quite a while, but he ignored his worries when the local medic was able to save Moira Dingle (Natalie J Robb) from a d.e.a.d.l.y situation.

That was orchestrated by John, by the way.

Mack concluded that he judged John far too early and since then, they’ve been somewhat civil with each other.

But everything is set to change next week. Mackenzie will make a discovery about John shortly after a huge row with Charity Dingle (Emma Atkins). We don’t know what it is at the moment, but the trailer is enough to confirm that uncovering the information about John will alter everything for Mack.

In the tense trailer, Mack is seen running through the woods. Eagle-eyed fans will also spot that this is the moment from Mack’s flashforward clip, which aired towards the end of 2024.

Mack dashes through the trees but ends up falling. Alongside these clips, we see John telling Mack that he has now ‘joined up the dots’.

While this is happening, Robert Sugden (Ryan Hawley) looks set to confront Aaron Dingle (Danny Miller). They will share a kiss on Monday, but Robert reckons that Aaron still loves him and doesn’t want to leave with John.

At the end of the trailer, Mackenzie is seen begging for his life as John throws a large rock above his head, presumably preparing for the moment he m.u.r.d.e.r.s Mack.

‘Guess I really am the bad guy’, John says.

If Mackenzie is m.u.r.d.e.r.e.d by John, it will be the first time (as far as we are aware) that he truly intends to k.i.l.l someone. When Nate Robinson (Jurell Carter) was k.i.l.l.e.d, John never planned for it to happen.

He gave Nate some medication and he had a bad reaction to it, leading to his d.e.a.t.h.

Could this be a sign that John will now become even more unhinged, ahead of his inevitable exit?

Lawrence Robb, who plays Mackenzie Boyd, spoke about the rumours of Mack’s d.e.a.t.h this week.

When appearing on the ITV daytime show Loose Women to talk about the ongoing surrogacy storyline – that has seen Charity decide to be a surrogate for granddaughter Sarah Sugden (Katie Hill) – the awkward matter of his upcoming exit was addressed.

‘I don’t want to put you on the spot, but I’m going to,’ asked Jane Moore.

‘There’s lots of rumours that Mack might be getting k.i.l.l.e.d off.’

Lawrence, visibly squirming, replied: ‘Yeah, there are lots of rumours. And rumours they shall remain.’

Quick thinking – though Denise Welch didn’t look too convinced.

Co-host Coleen Nolan then chimed in, asking: ‘If that was the case, I’m not saying it is or it isn’t, [but] do they discuss that with you straight away or about a month before it’s happening?’

‘It’s never brutal,’ he replied, being extremely cautious about his wording.

‘I’ve always said, being in the show, I never want to be too prescriptive with it.

‘I’ve always enjoyed doing what I’m doing. Ultimately if and when, – if, when – the time for Mack to leave comes, whether that be my choice or the writer-producers, I’ll be thankful for the time that I’ve had.’

He concluded: ‘Ultimately, nobody is safe in the show. It’s most dangerous village in the country.’

Mack made his debut five years ago when he turned up at Butlers Farm as the long-lost younger sibling of Moira.

He also swiftly embarked on a relationship with Charity, who was seeing Vanessa Woodfield (Michelle Hardwick) at the time of their one night stand.

In the years since, Mack has been at the centre of numerous stories, including a one night stand with Chloe Harris, which led to the birth of his son Reuben.
