As the being stepped back, Lyall took the chance to gather up Sandra's remaining cards to place with the rest of her deck. He eyed the being warily and with slight anger before turning most of his attention to his brother. The Infestation's influence had grasped him quicker than Lyall anticipated, especially considering the fact that his deck had already become corrupted to create a new set of monsters and cards. He needed to keep a closer eye on him, because if he didn't, Ryu was capable of turning completely evil or going insane. 

"You hesitated on that last part," Lyall told Ryu when he finished speaking. "Good, that means you're not completely at the edge of being far gone."

Lyall raised his right hand at Ryu and released a flash of murky light through the Iswarm crest on it. He was maintaining the infestation, wanting Ryu to still think clearly and to keep it from corrupting him further. The Iswarms were generally evil and destructive creatures afterall. Back in Aria City when Lyall had first released them, he had to keep them in check to make sure they didn't just go around destroying everything or running off to destroy other things outside the City.

"Tell me Ryu, how is the Judgment Dragon?"

That monster, along with Sandra's Chaos Fairy, would help in bringing Lyall's work back home to a conclusion.
