Assumption thrashed, avoiding Henry's hands and pulling his club back. A red mist swam through his mind and all he could think of was how Henry wanted to kill Walter and if he didn't stop him, then Henry would do it and take Walter away from him just as his mother had been. He brought the club down again, and again, striking over Henry's face.

Walter finally gathered his senses from Henry's blow, looking down and staring in shock as Assumption viciously beat Henry. He had seen Assumption fight other Pokemon and get really into it but this? This was completely different.
"Assumption." He tried to speak gently, awkwardly lowering himself and hesitantly reaching out to his Pokemon. He didn't want to try and stop Assumption and get caught up in his blind rage.
