Flint was NOT pleased that the boy couldn't listen to common sense. First the snake girl had used the slime to glue his weapon to the wall, now the boy wasn't even willing to stop what could be a greater threat. Rolling his eyes in exasperation, he broke off the half of the makeshift metal weapon that wasn't stuck to the wall and felt Bron try to kick the man who was at least twice as strong. However, as Flint was aware that strength did NOT equal capacity to root oneself(again, Ursa wrestling), he rolled forward out of the kick and tossed the broken metal bar at the snake girl, seeing it interrupt the slime's flight path. Bron was worthless now, but he was NOT letting the Faunus leave unpunished. Pushing off of the ground, he leapt over the snake girl, placing her between himself and Bron so the boy would be forced to help via going through her. It was there, with perfect timing as Flint noticed, Cereza came in with Taos on the back of a Nevermore. He didn't like the way she was controlling the bird, but she was still learning, and he couldn't have asked for a better moment as he picked up the now corpse's head.
"Those Nevermores DO get peckish, don't they?" he said to himself, tossing it into the air where the bird snapped it up, Cereza dropping Taos in response. One jump later and it was in his hands, where he gave it a quick riff to get inside the Faunus' head so he would have a pin on her location if she were to try and slip away, and to tell the Nevermore to take Cereza back to camp. Tink and Tank, both still semi-weightless, he commanded to split up, break range, and escape into the tunnels. And lastly, he called out to the oldest and most durable of the Death Stalkers, telling it to come to him and wait five blocks away for an expedient retreat if need be. While he wanted this girl neutralized, he did NOT want to be captured or killed, as he still had dozens of villages to burn. Landing back on the ground, he gave Taos a few swings, and started making the blade vibrate from the steady but minor release of Heavy Sound dust. Now, not only would it repel the slime, but it possessed a sharper cut.
"You think me a monster, yet would pardon a murderer for my head? My actions are done in revenge, yet yours appear to be merely in spite. SO TELL ME, BOY," he said, his voice building to a roar, "WHICH OF US IS THE MONSTER?" His words were regal and imposing, their effect amplified on the snake faunus, who would be getting that feeling the other Faunus got that maybe this Flint guy was someone to listen to and that boy was looking more and more like the target... At least, that was what Flint hoped she was thinking. She seemed a little bent off for your average Faunus, there could have been possible... side effects to her mind he didn't account for. As he spoke, he made sure to keep focusing on the girl's slime, watching to ensure that it didn't start attacking him again.
