Chapter 16: Describe Katniss(and Rues's) plan to attack the Careers' pyramid?

After lunch, the girls devise a plan. They will set up three campfires, which Rue will then light at intervals to distract the Careers so Katniss can destroy the Cornucopia. As a means of communication, Rue teaches Katniss her harvest whistle and they agree to send the message via mockingjays in case either is delayed on her way to the rendezvous point. Before they part, Rue hugs Katniss, an emotional move that calls Prim to her mind.
