At other times, things just skipped over either because so much has been stuffed in, or because its the easy way out. The eighth episode ends with Jack being shot (the Miracle removed his immortality making him the only person on Earth who can die) and the episode ends on a cliffhanger as Esther drives away with him. The next episode begins two months later with Jack pretty much in good health and the only explanation of how they got from America to Scotland despite all nations having closed their borders was that they got some people to smuggle them in. This is also the explanation for Oswald gets to Wales from America for the final few episodes despite the fact that he's a convicted murderer and paedophile.
Had this been an ongoing series (in a similar mould to Survivors or The Walking Dead), the huge amount of subplots would have worked as the writers would have around twenty-four initial episodes to leisurely set them up and let them develop. But because its a story that cant even satisfactorily span ten episodes in the way its written, the majority of the subplots are drawn out too much, left dangling, or resolved unsatisfactorily.
