Something made Kallik burn with each strike, and while Glaukos became aware of how voracious the boy was in his assault, he did not care. It was different from the other tactics during their training; he assumed this change was merely an effort to best his rival. A switch in his behavior.

Glaukos thought he felt Kallik deflate somewhat, after the hit. He moved to snap at him, and was met with teeth nearly gripping at his forearm, and so he had to move swiftly out of that before harm could be done. It took all of Glaukos' effort to pull away and to turn - when he'd rather be bearing down upon his assailant - and that saved him some obvious injury.

He was grunting with the effort, and was dissuaded from a timely counter attack, which left the boys separated; they could both catch their breaths now, which was a detriment to Glaukos as he wished to overpower. That was his entire tactic: overwhelm, overpower, dominate.
