There's a number of ways that Daud could respond to that, and the silence after she speaks is both long enough to considering them all and also to suggest he may not be intending to answer at all. He knows there's a response she expects from him -- whether or know she realizes it herself -- and when it turns out not to be what she wanted to hear, she'll only get angry all over again.

I haven't been alright for a while, Billie, he could tell her. Are those the words she's looking for? Is she trying to find the assassin he used to be, or the man he's become?

Daud isn't in the habit of leaving himself vulnerable. She'd probably have a hard time recognizing the man he'd been, near the end, confessing his guilt when the consequences of his actions caught up to him, waiting for a blade across his throat that never came. Had he done enough to earn his redemption? he'd wondered then. Not that it had mattered. Absolved of guilt or not, it had all burned in the end.

Maybe the bodyguard should have finished him off after all. Then he wouldn't have woken in the dirt a century later, to deal with all this.

"I'm not the one who's been dead for two days," is what the tiefling will settle on, finally. It's said ambiguously enough, with a terseness that communicates clearly his disinterest in having old wounds picked open all over again. "Don't make it a habit."
