Hannibal's ears detected the change in tone in his friend, and his brain automatically translated it and filed it away at the same time. It was a strange thing, to be privy to all these sides of Erik that the rest of the world did not see. It was likely strange to the other man, as well, given what he'd said previously about not being the sort to have friends. There was a trust building between them, and it felt like it was happening at an exponential rate.
"To die where you loved to be, to remain within the walls of peace and beauty forever, is a worthy endeavor." It didn't disturb him to hear that Erik had planned to die. Death was the natural end to everything living. It was only being in the City that Hannibal had seen and accepted that there could be other ends. Lestat, Pam, and Eric had all shown him that there was another life after life. Being a zombie himself had shown him that there was a more horrible sort of death that could linger, and Magdalene's arrival had informed him that such events could take place just about anywhere, that some saw it as their natural end.
He still could not, despite what his vampire friend had told him, believe in God or Heaven or any of that. He saw far more logic in what Erik wanted, for his bones to rest in a place that he was fond of, even if he would not actually be there.
"I have to admit, Erik, I did not imagine you the type to give up on anything."
