Remus looked back. At this point, he had already gotten to the 5th Step so he had slowed down his speed a lot. The 5th Step had always been his limit and he had never been able to traverse more than a few steps. But he knew there was no way that a first-year could ever hope to reach him, even if he was an Aura Knight.
When he looked back, however, he saw Leo just finish talking with Lyra and then start walking toward him. He turned back in annoyance. His opponent wasn't taking the entire ordeal seriously at all.
He took four steps forward and stopped. This was his limit. He turned around, sat down and waited. He was waiting for Leo to fail so that he could win the bet.
Leo smiled when he saw Remus sit down. He kept walking forward without showing any signs of being under pressure. As he was walking slowly, he got to the end of the 4th level in a minute. He was only a step away from the 5th Step.
