Wash raised an eyebrow as Casey bolted out of the room, waiting until he heard a door slam to look back at Bones. "You know he's lying, right?"

He quieted down at Bones' explanation, slowly closing his eyes. That...that explained a lot. "Greg defended her," he said after a few moments. "On the spire. Or- he didn't tell me what happened, at least. He said it was an accident - a mistake." Probably because he knew that Wash would put a knife through Peridot's gem if he'd found out what happened - an option that was still on the table, as it turned out. Evidently Wash wasn't as over the idea of revenge as he'd thought. "The way he's been acting, I wouldn't be surprised if he blames himself."
