As the battle continues, the two of them discuss how they're going to get rid of each other. They're both worried that the other's magic will overpower them, but they both realize that they've got to keep fighting, even if it's just for the sake of fighting. They agree that the only way they'll be able to fight is if they merge, and they agree that this will be the way to do it. They also agree that if they don't fight, the other will die.
