Read chapter 4 in hunger games. What's going on in that chapter?

Peeta offers to help Haymitch clean himself up. The offer makes Katniss grateful but also reminds her not to be too affected by his kindness since they will soon be opponents. She remembers again her early days of learning to hunt and provide for her family. One skill she mastered was identifying which herbs, roots and plants were safe to eat or use. She recalls how her father once introduced her to her namesake, the edible root Katniss, and how he told her "As long as you can find yourself, you'll never starve." Her memories make her feel guilty for having been too stern with her mother, and sad about home. She goes to bed without wearing any of the fancy clothes they've offered her. She knows her look will soon be out of her control, defined by an appointed Games stylist.

Effie wakes and then chaperones her to an overflowing breakfast. Watching the drunk Haymitch at breakfast, she realizes she detests him and wonders whether previous District 12 tributes lost partially because he was too much of a clown to line up decent sponsors. When Haymitch makes a joke mocking their plight, Peeta retorts sarcastically and Haymitch punches him. Katniss drives her knife into the table near his hand, and he realizes that he might actually have fighters this year. After verbally assessing their skill-sets, he agrees to stay sober enough to help them.

His first command comes as they arrive at the station. He makes them promise to acquiesce to the demands of their stylists, no matter what they think. Meanwhile, Katniss is overwhelmed by the grandeur of the Capitol, which is much more fantastic in sight than it ever was on TV. She is surprised to see Peeta playing to the gathered crowd, until he reminds her that by attracting fans, they attract sponsors and improve their chances at survival. She realizes again that she must stay wary, for "the boy who gave [her] the bread" is also playing a shrewd game that will ultimately mean he has to kill her.
