I'm not quite sure about what Peeta's up to, but I'm sure it's something clever. This chapter didn't feel as intense as the others before, but that's okay. (My heart needs a small reprieve every now and then.) I love how you've captured the characters' personalities.
Also, even though you may have actually meant it, you used "injected" instead of "interjected" at some point during the chapter. I don't know if it's necessarily wrong, but I thought I'd just point that out. Great job, other than that!
