Is there a NEW way to play with a time travel episode? Yes – shockingly – there is. The cause and effect issue of “the timeline” is always fun to get your mind around – but what if a terrible event is caused in the past by your attempts to NOT prevent a terrible event!? Didja get that? Heavy, right? And what if only by disrupting your rescue attempt will you ever find your way to safety? Woah. Awesome.
