With his adrenaline racing, Simms didn't register the thing digging into his arm right away. He hardly heard someone yelling at him from down the hall. He was just content to keep swinging at this kid's face until it was so swollen that he couldn't tell where his eyes were anymore. But Chase had hit him with something, and after landing a few more punches, he pulled Chase off the wall and shoved him down to the floor.
"The fuck is this?" he snapped as he scooped up the plastic shard, turning it over in his hands before flinging it angrily into the hallway. Having given Chase a couple seconds to breathe, he remedied that by turning and kicking him in the gut, hard. "What the fuck do you think you're doing? You want to be a fucking hero?" He grabbed Chase again, this time by the hair, and dragged him out into the hallway, pulling the cell door shut behind him when they both cleared it. He knelt down over Chase and pinned him by his throat again, punching him once more before just holding him by the throat. "I've been waiting to fucking hurt you, you fucking weirdo. I should just fucking kill you now."
But he didn't give Chase the chance to think that he might right there. He let his throat go, then grabbed his wrists and started pulling him towards the door to the station.
