Mack on Emmerdale on August 20, 2025 / ITV
Emmerdale star Lawrence Robb has admitted that his character Mack is about to find himself in “a dangerous position” as he discovers incriminating evidence about John (Oliver Farnworth).
Last week it emerged that Robb will soon be leaving the soap after more than five years, with reports suggesting that Mack will be murdered at the hands of John.
In next week’s episodes, Mack inadvertently stumbles on some evidence in John’s van that leaves him chilled to the bone, potentially starting his own demise in the process.
“Well, he hated him when he first arrived and all the way through,” said Robb, whose exit has yet to be officially confirmed. “He also hated him when he was with Aaron and hated him when John set him up with the slurry accident.
“But then John twisted it and used the slurry problem to help Mack get through it all, because Mack was really, really struggling. So ultimately, that incident brought them a little bit closer and Mack is now at the point of view of thinking ‘maybe you’re not as bad as I first made out; you’re still a bit weird, but you are with my best mate, so I can kind of get on board.’
“Then of course Robert pipes up and has words with Mack about John and says, ‘do you not think he’s a bit odd?’ And Mack agrees saying ‘yeah, I really didn’t like him, but he’s all right now’. I don’t think Mack and John will ever be in a position where they can go out and have a beer together. But there’s an element of an understanding between them.”
When Mack discovers the clue in John’s vehicle, “that changes the outlook entirely,” Robb continued. “It’s quite a critical moment for Mack. It is a mic drop moment. Suddenly Mack is like, ‘Oh! you are actually…. I was right about you the whole time’.”
As for whether Mack could be the one to finally bring down John, he added: “Look, there’s certainly a chance Mackenzie has the capability to bring John down. If he does – well that remains to be seen. But there’s potentially a very bleak outcome on the horizon.”
Emmerdale streams weekdays from 7am on ITVX and airs at 7.30pm on ITV1.
