Curious about something regarding Emet-Selch ***Endwalker spoilers***
He seems pretty dead set on stopping you, even knowing full well that you're Azem, all through Shadowbringers. Sure, he hopes to do it peacefully until the end, but he's obviously your enemy.
Then he's willing to help you in Endwalker. It makes sense, since you're trying to stop the thing that destroyed his civilization, but I wonder how much of it was motivated by guilt. When it was some unknown disaster, followed by Hydaelyn sundering them, Emet seemed to feel cheated, like his civilization deserved another chance and you were standing in the way of him giving it one. I wonder how much the realization of "well dang, we did this to ourselves" changed his mind.
Edit: I'm aware that the Elpis version is his past self. I'm talking about the Emet ex Machina where he shows up in Ultima Thule and revives the Scions.
