"I'm sorry," he murmurs. "I know. It's uncomfortable. But you've been left like this a long time. It will take... some time to get used to feeling it, I think.

It might make you sensitive, for while."

He opens his eyes.

"But I think it will help."

He has even less doubt about that than when he started.
