2020 Barry, 2014 Barry, and 2016 Barry all have to exist so that Current Barry can happen, but they themselves don't exist after that purpose as their times no longer exist exactly as they experienced it.

The only person who breaks the above rule seems to be Eobard, an incredibly experienced time traveler who might know how to bend the rules, but he could easily just be messing around before he has to go die. Or he could have altered those little bits at the end of season 1 with his new knowledge that Barry no doubt spilled. But that still wouldn't change much, and Current Barry wouldn't have the knowledge of him somehow getting away.

Who knows? Is anyone here a time traveler? I am, but i take a Waverider. It's less confusing.
