>>26722032>Silver never changed, not even a little.Did you stop playing after the E4? Silver started showing more love to his Pokémon at Victory Road, you see his attitude change at Mt. Moon, and you see that even more at Indigo Plateau in your rematch, where he managed to finally evolve his Golbat.
And Gary wasn't that big an asshole, but he was still abrasive, which is the point. There is never any amount of competition between any of your XY rivals, they're flat as cardboard and don't do anything besides "hey, we're friends! I love [character's gimmick]! We're friends!"
