Oh wow, you hated the guy that "destroyed" your world. What a huge friggin' shocker. Do you want me to weep little tears now that I knew you did and that you don't now?

[But it's....odd. Having that confirmation that he was genuinely hated. And being told by someone they were sorry that they did. And he doesn't really have any way to react to it beyond his usual behavior.]
