Katniss spend most of her time hunting with her now and arrow. Surprisingly being picked for the Hunger Games she uses her bow and arrow skills to win the games and ends up having to use them for the quarter quell.
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)
