^kinda has to be, though. Either a different resistance leader, or still one with that name, but a different father. It's great with the closed loop thing and all, but there has to be an original timeline leading UP TO that closed loop. Unless someone is arguing that this is even MORE screwed up, and no time exists outside of a 1984-2018 (give or take) bubble? Gotta have original conditions to create a loop with in the first place. Once you get into the loop, it can be self-perpetuating, and continue with stable itterations of Kyle, Sarah, and John, but before the very FIRST time travel occurance happened in 2018, there HAD to be an account of the past before that point...
No, as I said, that's the point of a closed loop being a paradox and all that. Nothing creates it except itself. That's why it's a paradox!
It's not that there's no time outside the loop, just that events inside that loop feed back on themselves. Just like in Red Dwarf
