I know that I'm late to this party, but I just got to watch the season finale last night and have been driving my husband crazy with the but, but, but's of the episode. So I decided to join a forum today so others could help me with the "buts". First, time travel shows give me a major headache because I over think everything. Now on to my questions and theories.
First, I don't see the ending as a wormhole, but rather time correcting itself. But where will it restart? The day Barry becomes the Flash? The day that his mother died? 2020 when he originally became the Flash? For the sake of the show, I must assume it will be around the time that he became the Flash. But won't that mean Eddie is still alive making everything up until that point null and void?
Say that the present is a set point in time and it only rewrites the past. Wouldn't that mean that Barry doesn't become the Flash until 2020? That Well's is just Wells and not Thawn/Wells? Barry's mother will be alive and well? If that is the case, will Cisco be the only one that remembers the alternate timeline? And that is only if the particle accellerator still exploded. But wouldn't that mean that Cisco would have to manipulate everything for it to all happen as it did? Otherwise, he wouldn't remember the alternate timeline.
See what I mean??? But, but, but......I have 1000 more buts, but these are the main ones that kept me up last night.
