Another post read: “I thought it was Mack,” backed by another viewer who commented: “I’ve just watched and thought it was Mack too.” A further theory read: “At first when I saw the beard I thought oh my God is it Nate?? And then I saw Mack… but now I don’t think it is Mack… or is it??”
The twist comes amid new flashbacks and details set to be revealed about John’s past, and what he’s hiding. In a scene kept secret until the episode aired, John’s struggles led him to a hospital where he visited a mystery man and spoke rather menacingly at him.

The unidentified man was in a coma, and John asked what he was going to have to do about him. It followed concern from John’s sister Victoria Sugden and his fiancé Aaron Dingle.
With John making mistakes at work and seeming distracted, he confided in Victoria about a time in the army where he medicated someone and they had a bad reaction. He’s been talking in his sleep and concerning Aaron with his behaviour, with John claiming this was down to what happened with Anthony Fox.
But things took a sinister turn at the end of Wednesday’s episode when he went to see the unknown man who was unconscious. He made the eerie comment suggesting he was trying to cover up whatever had happened.
