[Hiro puffs out his cheeks, frustrated. Bro, he loves you, but you really are way too nice for your own good.

He's already seen just how bad the consequences of that can get.]

But why? Why are you the one who has to feel bad? He doesn't! [He throws his hands up. He's trying his hardest to be better, to respect his brother's wishes, so he's not gonna try and kill the guy if he can help it, but that doesn't mean he likes Callaghan. Or that he can forgive him.] I bet you, if you got in his way, he wouldn't hesitate to let you die again. Or do it himself.

[Hiro's a little more selfish now where his brother's concerned. If he had a second chance, he knows this time he wouldn't let go of Tadashi's arm and let him run into another burning building.]

I don't...want anything to happen to you. Not again.
