[Hiro had expected Tadashi to be upset, but he's not ready for it when it happens. He flinches at his brother's tone; he still can't look at him. He runs hands through his hair, drags them down his face, all nervous energy and guilt and - god, now the feeling of messing up in a big way is as fresh as if it just happened.]

I know, I know, I get it. I screwed up. I just - he didn't care, about what happened to you, and he said it was your mistake, and then I...I dunno. Suddenly I was so mad I only wanted one thing.

[Not so different from Callaghan, in a way. The thought leaves a bitter taste in his mouth.]

...I don't want to be like him. Maybe he was right, though. He's escaped. I saw him, and even after all that I couldn't stop from getting mad. Maybe I'm really not cut out to be anything like you, either.
