Relief floods Stephen, both because no one had died at Kevin's hands and because Stephen will not have to handle the enormous mess that would be Kevin killing and eating a citizen of the Capitol.

"Oh, thank god," gushes Stephen, holding a hand to his chest. "That's fine. You can do that. Kill as many rats as you want, it doesn't matter. But please do keep in mind that killing actual humans is illegal outside of the Arena, and that any attempt to murder a citizen or another Tribute while in the Capitol will be severely punished."

He doesn't even sound angry. He just sounds relieved.
