Beyond any and all changes to Nora’s later timeline, Barry would need to navigate his daughter through outmaneuvering Time Wraiths, and whatever time-induced consequences that come up in the “present.”
As far as we can tell, Nora Allen went back in time in part to help Barry and the gang stop The Thinker’s Enlightenment, though no exact reasons were revealed.
Ultimately, it sounds like Team Flash will be faced with the question of whether or not the future is better off with Nora’s interference, which could have some devastating consequences.
She seemingly saved him from a fatal failure by turning back time and helping him destroy the falling satellite, and if so, then she effectively repeated the exact same mistake Barry did when he created Flashpoint after saving his mother, which is obviously a bad deal for everyone.
