Klaus knows that Irina is waiting for him, so he finishes the meal quickly and heads to the camp with Dairin's head in hand.
He appears in front of the group and raises Dairin's severed head toward them, provoking several reactions of shock and horror.
No matter how brutal and cruel humans can be to themselves and other races, the moment it's a non-human that starts ripping heads off, they get horrified.
"What kind of monster are you???" One of the slavers asks as he looks at Dairin's blood running down Klaus's lips over his bare chest.
"Monster? Oh yeah, you guys like to call me that..." Klaus scoffs as he shows his fangs. "I don't mind your hypocrisy; I like to play the monster role anyway."
[What the hell is going on???] The whole group of humans asks themselves the same thing.
"What are you waiting for??" Keld points his sword at Klaus as he talks to his teammates. "Let's kill this bastard!"
