The original Earth-1 timeline has been disrupted beyond belief, so I’ve no clue what it even looks like these days.
But wouldn’t it be interesting to get a gander at the host of different timelines that Nora left behind to see how things differed?
With those things in mind, isn’t it hypothetically possible that just about everything we’ve seen in Season 5 (presumably minus flashbacks) has been within a disparate Flashpoint universe similar to the one that Barry set up for himself in the Season 3 premiere?
