Quail to Mockinjay

Character Arc as defined by Robert McKee, is the process which "...not only reveals true character, but arcs or changes that inner nature, for better or worse, over the course of the telling."

If you can use just one element from this season's newest, Hunger Games: Catching Fire, use the character arc.

The ending and final image -

"The Hunger Games: Catching Fire ends on Jennifer Lawrence’s face: Katniss learns that District 12 is no more, and that they’re heading to the secretly resurrected District 13. Katniss goes from frightened and sad to angry and determined. She is the Mockingjay."

From Producer Nina Jacobson - “I love the choice Francis made to end on that close-up of Jen,” she said. “I think it’s so bold. And she’s one of the few actors who can pull off a moment like that: To let the resolution that you’re going to get be all emotional and in her face is, I find, really powerful. But we were really mindful of making people feel like a journey had been completed. That as a character she had advanced.”

Were there any other characters that experienced the arc?
