Ah yes, there it was, the question he'd been waiting for. "Emogen used to know someone very dear to me. Lieutenant Nathaniel Castle." He didn't want to upset Telyn, but he refused to lie to her either. She was his granddaughter, damn it, and Emogen had been his son's girlfriend. If he'd had anything to say about it, Jonas would have met Emogen years earlier than this, especially if Nate was still around. Nate isn't coming back. You saw him die. You knew it was true the moment you saw it.
He inclined his head. "Again, I'm so sorry to hear." And he was. He didn't want to see Telyn hurt, or to make that face again. By virtue alone, he was going to defend her. It would be harder for him to make it not quite so obvious. Somewhere, Selena was probably shaking her head at him right now.
