Kregg never changes his tone of voice, while talking to Mark. Even after Mark mouths off, all he does in response is punch him, wipes off the blood and continues with no change in tone. Delivered as good as always by Clancy Brown. I wonder if Darkblood will come back.
I wonder what Cecil and the Guardians will react when Mark comes back and telks them what Kregg has tasked him with. And Oliver of course.
Red Death sounded like the way Clancy voices Mr Krabs in that scene at points
