Probably a dumb question but who gets the third starter at the end? I've seen the rival keeps the two other starters you don't pick but maybe they give away another one? Or do they keep both of them around the whole game? If so then which one is the mega, the one with advantage or the weak one? If I pic idk Paxton and Tepig will Taunie always use Feraligatr as a normal mon and Mega Meganium as ace or the other way around?
