Confused by the events going on before him, Gregor stood back with the fireball growing inside his jaws. Did the caveman just really collapse the cave? He might be more dangerous than he looks. But whatever, they could deal with him when and if he becomes a problem. After all, he had shown no hostility to anyone but the inanimate cave. For a moment, Gregor considered launching his fireball at the mysteriously reappeared Arthur. He knew little about Arthur, but Adrian had told him enough to know that he needed more firepower still. So he kept charging, in the hope that the dragon girl would cover them.
