There's one thing I can't figure out about Thawne's reverse Flashpoint. After all the trouble he went through to create it, why would he allow a device with the potential to undo it exist? seriously, you'd think he'd prevent the PED from being created or at least destroy it, since he should've known that Barry would try to find a way to undo it. He shouldn't have left anything to chance, but since he did, it all backfired on him and left him in a lose lose situation. Either he dies or he loses his speed. Either, that one oversight led to the death of the Reverse Flash.
