Renji frowned. "People disappear all the time," he said. "I knew one that came back. But he didn't remember anything that he'd done here. And he remembered more stuff from back home than he had before." He shook his head. "I just know when they're gone, I can't find their souls any more. Which normally means they're dead, but maybe not in this case." He considered the rest of what Allen had said. "If he was just wearing his uniform... well, I found my uniform in my room last night, and that might've happened to other people. But if he had his weapon and was fighting the other prisoners... well, that happens. Every other night. They take some people, do stuff to them, and for that night they work on Landel's side, whether they want to or not." He stopped for a minute, staring down at his plate, his lips compressing into a thin line. No, he wasn't going to think about it. He gave his head a short, sharp jerk, then looked back up at Allen. "So it's not his fault, if that's what happened. On the nights they don't do that, that's when they take people up to that hallway and torture them."
