"I look up into those blue eyes that no amount of dramatic makeup can make truly deadly and remember how, just a year ago, I was prepared to kill him. Convinced he was trying to kill me.

Something flickers across his bloodshot eyes. Pain.

"Like you said, it's going to be bad no matter how you slice it. And whatever Peeta wants, it's his turn to be saved. We both owe him that." My voice takes on a pleading tone. "Besides, the Capitol hates me so much, I'm as good as dead now. He still might have a chance." (Chapter 13)
