What's the point with that quite lackluster story in Endwalker?

[KariTheFox]

Y'shtola would have to have known that Zodiark was the one who stopped the Final Days after all the research she had done in Anamnesis Aynder, moreso then any of the other Scions.

I think mistranslation is the only logical explanation in this case.

I just listened to the cutscene in Japanese, my Japanese isn't perfect but she seems to be saying that Hydaelyn was around to bind Zodiark when the Final Days were happening so she would know what to do.

(Or maybe she knows something because the Final Days remained forestalled even though she bound Zodiark, like I said. Not perfect.)

Edit: the point is that she doesn't seem to be crediting Hydaelyn with anything except binding Zodiark in the Japanese. It's a weird line in English that doesn't reflect her prior knowledge or later conclusions. So using it as represe ntative of her stance - next to the later one especially, strikes me as cherry-picking.
