[ Hannibal's expression briefly shows a bit of doubt at Percy's statement, though he doesn't challenge him on it. It's just an odd thing to hear, because heroism, myth, and all of the ideals that Hannibal genuinely admires as a reality for Percy. They're only a fiction for Hannibal, and so for someone to call themselves a hero is still odd. He had accepted Yuna's proclamations without comment, though he had found them a bit presumptuous, but Percy's tired, world-weary tone gets him to at least believe it a bit more. Though he does think that the idea that Percy doesn't get a choice in it is a bit unfair.

He's not really inclined to speak about heroism, though. It's a subject that is a counterpoint to him, and so he answers the question instead. The answer itself is... Probably more simple than Percy would expect. ]

She asked for my help. [ A pause, and then: ] Will's, technically. But he volunteered my assistance. Because she asked, I knew I could trust her. If she chose to betray us, then it would have been unwise.

[ Even in those casual words, there's a sinister edge, because the implication is clear. Hannibal wouldn't have been satisfied with letting Chane take him down, even if she were to come with him. So they had kept each others' secrets, and Hannibal felt secure enough in that. ]

My poster is completely accurate, I find. "Complete and utter hedonism"— It's a succinct summation, and too succinct, in truth. And hedonism is living without regret. [ Hannibal pauses. It's a longer pause, and a thoughtful one, but again, he decides to give honesty. It's not quite what Percy was asking, since it's vague, but it's meant only to hint at an explanation. ] I have only regretted one thing in my life, Percy. I chose to abandon the concept of regret after. So, no, I do not regret it. I never will.
