The understanding of the Games by the people in the Capitol has changed because they are witnessing a shift in the way the tributes, particularly Katniss and Peeta, are perceived. Previously, the Capitol audience treated the Games as a form of entertainment, oblivious to the suffering and brutality involved. However, Peeta's announcement of his and Katniss's love for each other, which is perceived as a genuine act of defiance against the Capitol's control, has captivated the audience. This marks a departure from the usual scripted, emotionless tributes and exposes the genuine cruelty and manipulation inherent in the Games. The Capitol's shock and chaos stem from the realization that the tributes, who were supposed to be mere pawns, have the capacity to resist and expose the inhumanity of the Capitol's regime. This awakening is a crucial turning point in the story as it triggers a shift in the Capitol's perception of the Games and sets the stage for the rebellion.
