>>30082664I think youre forgetting one thing. Lusamines abuse towards Lille started when Gladion left. So they were working on "Type:Full" the UB killer well into Lilles infancy. That is what Gladion left Aether with. It would seem conclusive that they have encountered the UBs (specifically Nihilego) years before the plot.
I dont think its a stretch to say within those years, she was being controlled. Not saying youre wrong, just offering my perspective.
