Peeta stares at the doctor for a minute, and he's not sure what to say. Not becaues House has a cane but because he's both not used to doctors and because he's never heard a doctor be so brusque.

Not that Peeta knows many doctors in the first place.

"I'm Peeta Mellark. I need advice about my leg." Peeta pauses for long enough for it to be considered stopping. He's never discussed his prosthetic with anyone, not even with Katniss. She knows it's there, of course, but they don't talk about it - it makes Katniss feel guilty.
