I still don't know where it is at that the Ascians are like, "We need to hurry hurry hurry, y'all!" Can someone point to the point in the story where it happens?

I'm still also inclined to take anything they say with a grain of salt, because like, Lahabrea was all, "We will need the primals in order to get the calamity going." But like, nah, not really. They resort to a chemical weapon to kick off the 8th, which did happen in one of the timelines. No primal involved at all. Ascian words are as air.
