From the start, Peeta does everything he can to help Katniss survive. He joins the Careers in order to lead them away from her and even fights off Cato, who wounds him badly. To survive, Peeta uses his exceptional camouflaging skills to hide until Katniss finds him and nurses him back to health. While Katniss doubts Peeta's love for her, thinking that he is only keeping up the "lover boy" act, he seems genuine throughout the novel and feels betrayed in the end when he discovers that Katniss has not been as sincere as he has.
