As soon as Mato reached into the apartment to toss the steaks, Jawsey flitted into the empty apartment to one side, then through the wall in hopes of catching the Hellhound by surprise. Unfortunately the 'steak' had fallen short and the beast was writhing on its chain, and more than ready to fight.
The hellhound was quick, for a being of meat. Jawsey was as quick as he could think, and thanks to AM's spell his thoughts were quick indeed. While the hounds was still lining him up for a lunge, Jawsey was flying over its back, intending to rake the astral part of the hounds make-up. The hound twisted faster than Jawsey had expected it to and he almost missed, but then he just stopped. The hound, slave to physics, continued its spin, bringing its head right into position for Jawsey to slam his feet into the beast, sending it staggering.
The hellhound was staggered, but not willing to give up the fight. It snapped at Jawsey, but the elf was easily able to fling himself back through a wall and out of reach -- and then to charge right back, smashing into the hound with the full force of his will.
That seemed to have been enough, the creature's aura confirming it's lack of consciousness.
After a moment Jawsey pulled himself together from the adrenaline of the fight, and manifested next to the boy.
"I took care of the hellhound. My team mates will be here in a moment to free you, and we'll get you out of here. The more that you can cooperate, the faster we'll get you away. Now, is there anything we need to know?"
