DOUBLE THE GIFS OF KATNISS! The scene that the last gif is from at the end of it she says "I love you Peeta." If you listen carefully you can hear. At first when I heard about I wasn't sure but I watched it again to make sure.
At first shes scared, because she wants to live. Then in catching fire she's unsure of who she is. In mockingjay, she is pissed off at the capital for destroying her.( and I got that from her facial expression)
