Answer:
Katniss is at first so angry with Peeta for his comments, believing that he made her look weak, that when they get off on floor 12, she shoves him. He knocks an urn over, shattering it, and then falls and cuts his hands on the shards. Haymitch, Effie, Cinna, and Portia find them there and explain to Katniss that Peeta has made her look desirable, that the entire Capitol is talking about her, so Peeta has, in fact, done her a huge favor. She apologizes to Peeta and, again, feels that she owes him.
That night, she and Peeta say goodbye to Effie and Haymitch, who will go to the Games Headquarters. Haymitch's final advice is to start running at the sound of the gong, to ignore the Cornucopia and put as much distance as possible between themselves and the other tributes, and to find water. That night, sleep eludes Katniss, so she heads up to the rooftop to get some air. She finds Peeta there, his hands bandaged. They talk about the Games that will come tomorrow. Katniss has been thinking about the landscape, hoping for trees, while Peeta wants to make sure that he remains true to his identity in the Games, that he doesn't turn into some kind of monster in the arena. Peeta doesn't think he can survive the Games, and when Katniss offers encouragement, they argue and Katniss leaves.
The next morning, Cinna and Katniss take a hovercraft to the arena, a place that becomes a tourist hot-spot when the Games are over. Katniss has a tracker injected into her forearm. After they land, she goes underground to the Launch Room, or the Stockyard as the people in the districts call it, and begins her preparations for the start of the Games. Cinna helps her dress and does her hair in her trademark braid down her back. Then, he pulls out the gold mockingjay pin that he found on the shirt that she left on the train. He fastens it to her shirt, and they hold hands until it's time for Katniss to enter the arena. Cinna says that he truly believes that Katniss will win.
A cylinder carries Katniss up to the arena, where she's met by bright sunlight and the voice of Claudius Templesmith, the Games' announcer, marking the beginning of the 74th Hunger Games.
