Emerald implies that Groudon and Kyogre don't even hate each other, they just can't control their own power once awake and can only manage it by clashing against each other. Rayquaza's presence causes them to regain control again, and they leave Sootopolis peacefully. Archie and Maxie watching this realize that their efforts were probably both pointless in the face of nature's might, and also the wrong way to go about it anyway, and they leave peacefully too, to make amends.
