Joshua was strong, but he was also outnumbered. He hissed at them, as Henry and Iestyn - as tired and hungry as they were - both came at him. He pulled a flick knife out of his pocket and he opened it in one fluid motion, charging straight at Henry, until he managed to pull Henry into his arms, the knife at his throat. "BACK OFF!" Joshua yelled to Iestyn.
Henry froze in fear, and the fight went out of him. He was dragged out of the cell, the door slamming behind him. He wasn't taken far though. Instead he was just shoved up against the bars of the cell opposite Iestyn's, and then Joshua handcuffed him up there, his arms stretched out above his head.
Henry wanted to beg for him to stop, or to ask what was about to happen, but his voice seemed stolen in fear. Or it was, until Joshua grinned and then buried the flick knife's blade deep in Henry's abdomen. Henry screamed and Joshua laughed, stepping back to marvel the knife's hilt, sticking out of Henry. Then he chuckled all the way back out of the basement.
Henry was stuck staring down at the knife in his belly, and he could do nothing about it. His arms were chained over his head, and he was too far away from Iestyn to reach. So he breathed heavily, distressed, panicking. Oh god, he was going to die!
