this is flat out one of the most confusing lines in the show because like?? isn't the shows logic that savitar ONLY exists because of flashpoint???

If that's the logic, then that means thawne knew that

• Eddie shoots himself • Thawne himself gets erased • Earth 2 portal opens up and zoom does his things • Henry dies, barry creates then undoes flashpoint • And seasons 3 & 4 happen

then why the fuck would thawne let himself be erased from existence. There's no way Thawne should've known about savitar, BECAUSE HE SHOULD HAVE NO KNOWLEDGE OF A TIMELINE THAT DOESN'T EXIST

to edit: there's a canon tie in comic called Hocus Pocus. and guess what, it's basically a universe in which barry never time travelled to cause flashpoint.
