Interesting gundam witch episode, mostly just confirming the obvious suspicions. Eri died in the prologue but achieved such a high permet score, all of her consiousness was still within the permet network. Permet is some sort of resource that holds and shares data. Sulletta was a 'replichild" which seems self explanatory. What wasn't super obvious was that the gund bit controlling eris are also replichildren, so they are basically just eri's consciousness copied several times in the permet data storm stored within aerial. Everyone seems united in their cause of removing sulletta from all the plans around quiet zero for her own good which is frustrating to watch, because obviously she's going to get involved again, but perhaps as her own person.
I suspect Miorinne's plan won't go very well, since shadiq and dawn of fold are behind the riots, but who knows at this point.
