Catching Fire Plot Twist

In the second book of "The Hunger Games Catching Fire", there is an unexpected plot twist towards the end of the story. Katniss has just shot an arrow at the arena to destroy it. This is when the twist begins. At first I thought she was going to kill the remaining tributes and continue on with the games, but instead she remembers who the true enemy is and destroys the arena. Once the Capitol is destroyed. A hovercraft picks her body up and once she awakens from her drug induced coma, she sees Plutarch, Haymitch, and Finnick talking at a table. Plutarch is the new game maker, but now Katniss will soon see that he is part of the rebellion against the Capitol. Plutarch explains to Katniss that these tributes were chosen to help in the rebellion, and that they are headed to District 13. Katniss thinks that it doesn't exist because it was supposedly destroyed completely by the peacekeepers. This plot twist sets up for the next book of the series and changes the readers whole mindset on what is going on in the novel. I like the plot twist. I think it keeps the trilogy going, and it adds a little excitement and anticipation for the next book.
