i do just. think about satoshi interacting w/ fallers (outside his friend circle) & realizing that prolonged exposure to ultra aura has had adverse effects on Majority of like. normal people. & even some not quite Normal(tm). there's people that have lost swaths of their memories to varying degrees. they typically become targets for hostile ubs, not simple points of curiosity. & then there's satoshi who regularly cozied up with his ubs, both poipole & nebby, & indeed has explored ultra space with nebby's guidance with only pikachu with him, meaning of all the people he knows he's had the most exposure to ultra aura, loitering in ultra space, taking his sweet time there.
