Katniss is back from the Capitol with Peeta as winner of the hunger games, and now they are being showered in fame and glory. Not only did they win but they are the first ever two victors; now they must keep up the lie of them being star crossed lovers for the press or Else they will upset many if not all of the districts because they cheated the hunger game. when Katniss got back home to district 12 she was welcomed with a surprise visit from President Snow who was sitting in her living room. During the visit he implied that he didn't like being fooled and the there would be repercussions on katnisses part.
After the Hunger Games, Gale and Katnisses relationship isn't as strong as it was. I think a contributing factor to their relationship no being as strong is all the talk about Katniss and Peeta being star crossed lovers, and the time they spent apart.
Katniss seems to be mostly concerned about will her behavior at the games have effected the people she loves. especially after the visit from President snow?
