Dante narrows his eyes at Banks' words, but doesn't otherwise respond to an obvious scathing jab. It's not a question that needs a reply, both of them know that, and so he isn't going to devolve whatever Banks intended with this into an argument about his feelings on the matter. Frankly, he's too old for that kind of shit.
Instead, as Banks states his negative to Dante's sort-of-invitation for a conversation, he sits up a bit more with a deep sigh. Dante gives the younger man a nod, slow and lingering in its motion, one of subtle agreement in the statement that follows the single syllable. He'd no qualms about it, even if his conversation with Rafe hadn't been quite so productive. The two don't strike Dante as incapable in the slightest; on the contrary, they carry themselves with the kind of experienced intention and confidence one earns only by having fallen and gotten up by one's own strength so many times.
In a way, if situations were different, if sentiments were different, he'd be proud of the two of them. Hell, he is proud, but he knows that neither Cawela boy would quite appreciate that acknowledgement from him.
Then Banks just comes out swinging, directly, with a question his older cousin hadn't even gotten to. Rafe had shut him down almost immediately, had made it clear that he doesn't barter in excuses, and the topic of his auntie hadn't even managed to come up so concrete as Banks put it. Had he abandoned his auntie? Perhaps, unintentionally, by being on an entirely different continent, trying to serve the Commonwealth, as foolish as tht turned out to be. And he's still doing it, isn't he?
"My child," he tells Banks, the same reason he had given Rafe, the reason Rafe had shut him down almost abruptly. Whatever problem the older Cawela cousin seemed to have with him, it didn't extend to Dottie, and trying to hide behind it, as Rafe had put it, hadn't won him any favours. But then, it is the honest truth. "Her mother had stolen her, kidnapped her, and, as it turns out, had attempted to drown her not long after the fact. I'd spent the better part of nineteen years trying to find her. And her mother."
But that's not the least of it. "I wrote every week. But," Dante sighs, rubbing his hands against his face slowly. "Your cousin told me you've served just as I have. And therefore I don't need to explain to you that the Commonwealth Army strictly serves itself. They were the intermediary between us. If your grandmother didn't get any messages from me, it's because the army we gave our lives to didn't want her to get them. Not because I didn't send them."
He drops his hands, a frown deepening lines etched into his face from a lifetime of worry and anger and fighting. "Look, lad. Maybe my apology won't mean shite to you like it ain't mean shite to your cousin, but... for what it's worth. I am sorry. Lot of shite I regret in my life. This is one on a long list of 'em. But my child... she ain't one of 'em, right?"
