Mirror

Katniss feels like she is living a double life. As she looks in the mirror, she no longer recognizes the person that is staring back; she's lost her identity. No longer is she the girl in the blue dress who volunteered for Prim at the Reaping. No, she sees the girl on fire. Katniss tries to balance these two parts of her. One is the huntress, who finds refuge in the woods of District 12 alongside her best friend, Gale. The one who does anything she can to keep her family alive. The person she was before the Reaping. She desperately wants to be that person again. She wants to "forget the fires" she has started, more specifically the rebellion and her momentous contribution to it. But she can't. She has too much blood on her hands. She is a winner of the Games, but being a so called 'winner' is costly; the price being the lives of others. She is haunted by that fact. The other part of her is the Girl of Fire; the Mockingjay. The same girl who won the Hunger Games. The same girl who is marrying Peeta Mellark. The same girl who twirls in burning dresses and the same girl who is, in a way, completely different than the other girl. But she's sick of pretending. She's sick of being made into something she's not. She's sick of the cameras, the makeup, the glorification of it all. But at the same time, she knows that there's no going back to the girl she used to be. So she's stuck in the middle. This leads nicely to next book/movie, because it is then that she combines these two different versions of herself to become the Mockingjay. She ends up genuinely loving Peeta and fighting for the cause, yet she still keeps her inner fire.

I haven't found it written out on any lyric sites yet, but I could swear that in the last chorus, it goes:

"I was the girl who was on fire (A hero) I was the girl who was on fire (A hero)..."

and then the rest like it's written. It may be just a background vocal effect, but I feel that it's really powerful and extremely important to the song.

um yeah
I was the girl who was on fire I was the girl who was on fire Only a bird could get much higher (I look in the mirror) 'Cause I was the girl who was on fire
