Lucy comes to a halt, turning hesitantly back towards him. That surprises her, actually. For a moment she wonders if he's just trying to appease her, but then she remembers that he's presumably forced to tell the truth just as much as she is. Not that this news exactly makes her jump for joy. Big deal, he's not sleeping around. It doesn't mean anything. Right?

"You're gonna have to do better than that," she tells him after a few moments. Another tear spills as she says it, but she's reasonably collected now. It's like she's resigned herself to the worst possible outcome.
