All of a sudden, the king starts hearing voices. Someone, a blue blood, is taunting him, saying that he gave the Windsor the kingdom and that he's isn't respecting the gift he received. The king gets scared, pulls out his gun and starts firing wildly, killing all his guests. As he's shooting, a hand grips his head and crushes it. Regis, the owner of the hand, appears out of thin air and tells Yngvi that he can rule now before saying that they're going to war. He goes to eat the former king's children.
