Instead of answering immediately, there's a little pause, big enough for Dankovsky's trained eye to spot. She's not looking at him, more at some distant point in her mind, on things that there's no way Daniil could know about. It's an innocent question. She ought to laugh here. Laugh and shake her head and say-

"Yes."

Not that. But it slips out too easily, quiet as it is. Not a point of pain. Merely sensitivity.
