Power Walker had no idea what had happened between Silent Walker and Gravis.
However, just an hour after Silent Walker went silent, he told Power Walker that he and Gravis had come to an agreement.
Silent Walker used his "Law of Honesty" to tell Power Walker that their enmity had been solved.
They didn't need to keep Gravis here anymore.
"It's good that you know your place," Power Walker harrumphed. "This time, you managed to survive thanks to the kindness of my junior brother. Don't anger him again, or you will die."
"I won't," Gravis said with a smile. "We came to an agreement, after all."
"You can escort him back to Opposer City," Silent Walker said. "We don't need the full five years."
Power Walker threw some more reprimands at Gravis, but then he escorted him back to Opposer City.
An hour later, Gravis was back in Opposer City. Power Walker handed Gravis over to the guards, and Gravis gave his emblem back.
