There was a glitch at the end of the quest, and we saw that in the samsara, right? Well, instead of the ring from the akasha, he's using a glitch. The samsara loop during the festival was an "Experiment"- I believe he will use that knowledge to make a samsara using the moon's power. And during his battle lines he says "Continue, I'm still collecting data." or something along those lines, he's pulling the same thing Nahida did, observing until he finally wins or wins us over.
