Mithias heard the response, but it was only an empty word, one that could have two contradictory meanings. Either this kid was in regret of his actions and unable to control them, or he was being facetious, very likely for an impudent youth. But Mithias left both possibilities open to consideration as he reacted. 

As the tiny shard golems swarmed and the train-hammer of a frozen fist accelerated toward him, the vampire felt no rush. He leaped up onto the incoming arm, compensating, as its momentum was dulled by its impact with the magical fox and weasel. Using his supernatural strength and grace, he Legolas'ed his way up the arm onto the shoulder, and then onto the back of the primary golem's neck. Finding a moment to draw his blades, Mithias plunged both steel fangs into the ice at the back of the golem's neck and used them to hold on, like handles pitched deep into the ice. 

Did he really know what he would do? Not entirely, but riding the golem was pretty entertaining. Seph had said to break open the black orb, if possible, and it was currently directly between Mithias' blades. The vampire extended his senses, feeling the life inside the monstrosity, hearing the beating of a living heart. The child was there, yet what to do? Applying his pyrokinesis, he could try cooking the child, but what if the kid truly was sorry? ... It would be such a waste of young blood. 

Mithias looked down at the others from his precarious seat. They seemed fine while the golem was flabbergasted by being mounted. He thought he'd try one more option, a threat. "You'd better hope you can hear me, child. Cease your movements, or I will burn you alive from within your construct."
