In Chapter Nine, when each of the contestants of the Hunger Games are interviewed, it is Peeta that is last, and it is Peeta that manages to steal the show by his confession of love for Katniss in front of all the cameras and Katniss herself. Note how the chapter ends with this revelation, that is a surprise to everyone, most of all Katniss. Having been asked why his love is so impossible, Peeta responds:
Peeta blushes beet red and stammers out. "Because... because... she came here with me."
This of course gains them both universal sympathy and support, as impossible love situations always manage to engage the public and the media. However, at the same time, as we consider the personal drama going on between Peeta and Katniss, this leaves Katniss very unsure of what is happening, as she doesn't know if this is just a cynical ploy of Peeta's to gain support for him or if this is genuine.
