We are now falling into the next stage of the story, which involves the first 2 significant world line changes (Ignoring the first, most critical one for now). The show now bombards you with clues, which later you will need to try and work out what is occurring. Its of interest, but nowhere as captivating as the first four episodes. I suspect the objective is to make it less dramatic so the next stage of the series is much more shocking. Not as good as the last episode, but certainly not a bad episode.
