The season finale of The Flash ended in a shock in that Barry Allen, as we know him, no longer exists. Follow. Our Barry went into the Future then returned to slightly before he left. It was our Barry who ran in the opposite direction, stopping the magnetic ring of doom that would destroy the multi-verse, thus it was our Barry who was disintegrated in the Speed Force.
The Barry who destroyed Zoom and also ditched Iris was the second Barry, a copy, “created” by our Barry returning to the past before he left. It was this second Barry who traveled back to the Past to save Nora, Barry’s mother. Second Barry rescued Young Barry and his father, as well as killing Reverse Flash outright and saving Nora.
But when Second Barry did that – you’ll notice that First Season Barry, who was watching disappeared. That is because First Season Barry – the one we’ve followed through two seasons of The Flash – no longer exists. As Zoom predicted Second Barry has now destroyed himself twice, as well as Zoom and Reverse Flash. This Second Barry is the only Speedster left, assuming he also didn’t wipe himself out of existence in a paradox.
Think about it – with Second Barry destroying Reverse Flash and saving Nora, that means young Barry was raised by Nora and Henry Allen. Nora never died. Henry was never accused of and found guilty of her murder. Young Barry was never sent to live with Joe West. Young Barry may have never even met Iris West, much less fallen in love with her. And, to make things worse – Young Barry would have never been driven to become a police officer – or with Joe West’s influence to not be a cop – to become a forensic analyst, a CSI. That Young Barry probably went to college, given his parents, but who knows what he studied – or if he even returned to Central City after college. There’s no reason to assume he’d become a CSI anyway. And he never became The Flash.
But it’s worse than that – because without Barry, What would have happened. Thrawn mentions Dr. Wells Particle Accelerator happening “15 years” later and he needs for it to happen earlier. Thrawn also rigged the explosion that created both the MetaHumans and The Flash. Did this never happen? Did it happen differently? Second Barry may have created Earth 2 where Barry has no powers, Caitlin and Cisco are “evil” – Killer Frost and Reverb, specifically, as well as giving rise to Zoom in the first place.
Also, don’t forget – in the finale of Season 1, Barry goes back in time to save his mother and stop Reverse Flash. Yet, in the house – he’s warned off, by himself. In Season 1, Barry heads the warning of, well, himself, and Nora dies. Now, we have an alternate timeline, and a second Barry goes back in time, saves Nora, and Barry (our Barry) disappears. What is going on?
I’ve seen the animated Justice League: The Flashpoint Paradox, which I’ve also reviewed, but I haven’t read the 6-book Flashpoint (and World of Flashpoint) series from DC Comics. However, with DC’s new Rebirth maxi-series picking up from Flashpoint, and the fairly consistent dropping of Flashpoint hints and references in CW’s The Flash, one thing’s for sure, next season is going to be very interesting.
