Kyle whispered to her, "You." He was a hunter, and also a good tracker, and a good listener. He heard someone outside. He pulled a giant pistol with two wheels for bullets out. He loaded the gun with heat-detecting bullets. "These will go right to the heat source. And, of course, kill your little helper. What do I do in my spare time? I'm an engineer. I create things. Most of them are good." He smirked and winked at her, then stood up and went to the door.
Outside, Kyle's little brother, Ordo, grabbed one of Kyle's big loaded guns and shot it multiple times at the clawed boy, then ran away laughing. "Fight bullets! Fight bullets!"
Inside, Kyle listened as bullets shot ever towards them. They would find the closest and most powerful heat source, and pummel it. He opened the door a crack and shot another round for good measure. Then he shut the door.
Darcy and Erica reached the market, and everybody in their group was waiting. Their group, or clan, or pack, was called Thrust. There were other clans, yes, but they had different names: Claw Clan, named after their long metal claws on their hands, Turn Clan, the evil clan in the area that had been known to fight with screws and nails, but also... other things. Kyle was part of that group.
