Peter is quite good at saving his own neck...though she might be surprised to know he has at least a little glimmer of honor, deep down. He may or may not have expended it all by now, though.

'When'd you get so tetchy?' he wants to ask. He even opens his mouth (or his mind, or however he's been speaking) to say it before he gives it a good bit of critical thought and decides it might count as complaining. "Fine," he says instead.
