The good news was that Chris died quickly. This was good news for both of them because it meant that Chris didn't have to suffer much and Arthur didn't have to waste time and effort killing him.
After making sure that his enemy was dead, he released the guy's spine and let his deformed body drop to the ground. Then he cleaned his arm and gauntlet with a spell.
While cleaning his arm, he said to Roar, "In the spirit of not wasting, you should come and fill up your stomach with this."
Roar came over eagerly to eat the corpse. Meanwhile, Arthur glanced at the other four to see if they wanted to fight too.
But the other four took off as soon as he glanced at them. So he shrugged and grabbed the space pouch of the guy he just killed so as to look through it.
While he was doing this, he walked back to where Thor was. Then he resumed storing their loot.
