Sorry to hear your news @strugglingwithlife . So hard for you but hope you've got supportive people to help you get through this.
I'm also confused about John's ability to time hop. He drove off with Mack alive, apparently killed him then came back to the Woolpack. Then he drove off with Aaron in the front and Mack in the back, arrived at a holiday cottage then nipped ouf to bury Mack. Doesn't Aaron wonder where he is or have I got the sequence of events wrong?
