"Prim," he says, taking a couple more steps forward before he crouches down in front of her, "it's okay. I'll look out for you."

For once, looking out for a kid he's not about to send into the arena? I'll be a nice change.

He doesn't know if what he's been told is true, if this is a scheme of the Capitol or something far bigger, as if that were even possible, but he does know this much: he's got to look out for her. Political calculations aside, Katniss and winning her over to the rebellion aside, she's just a kid, and she needs help, and there have been so many kids over the past ten years he couldn't help.

If she looks at him and into those piercingly green eyes, she'll see nothing bt sincerity there.
