Found this on DS: “With Mackenzie still struggling to cope trapped in the bunker, he takes desperate measures and injects himself with the syringe John left for him-then starts hallucinating. Meanwhile, Aaron finally wakes up in hospital and everyone’s desperate for answers, particularly Charity. As Cain arrives and reveals that he dropped John off at the cottage, DS Jordan quickly rushes out. When Aaron the mentions a bunker, Charity is soon on his tail.”
Also saw that it’s nearly the end for John for now - aargh!
