>by merit of her complete lack of acknowledgement towards them the game effectively goes out of its way to imply ALL of the Paradox Pokemon conveniently decide to fuck off from visible view in Area Zero so Briar never has to perceive them and come to the conclusion of "holy shit HEATH WAS RIGHT OH GOD I'M GONNA FUCKING CUM" prior to finding Terapagos
My literal only thought about this is that narratively speaking, this is supposed to be the part where all the paradoxes get dislocated to start appearing during Heath's era, like how the professor's dislocated to Kitakami for a bit. They were just too lazy to actually disable all the spawn flags for the paradoxes for gameplay purposes until you caught Terapagos.
