Hijacked Peeta Mellark
While Peeta Mellark was captured by the Capitol, President Snow hijacked Peeta's brain to think that Katniss is trying to kill him. Peeta also thought that Katniss was the one to kill his family. He said," It's her, she's the one that caused all these people to die. My family is dead!" (Mockingjaypart2) luckily the doctors of District 13 help Peeta trust Katniss again, and he is not hijacked during the rest of The Hunger Games Series.
