Pretty much all of this! ;)

I like how she starts off so damaged, then things get worse, but she kinda took charge of that bad situation and used it to grow stronger. We see her broken and the she rebuilds herself. Pretty epic.

^exactly.

Her character development is one of the very few these days that are interesting, meaningful and epic. How she started off as a little girl being dragged, used and controlled by her brother, to where she is now.

I like all of these, her strength of character, her fierceness, her storyline, but her character development the most, she has changed allot since we first saw her as the used, controlled and timid person she was, i love how you see her grow into a confident leader that learns how to control any situation she gets into, she soon becomes unafraid to challenge peoples preconceived notions and by the end, ends up on top. Her character development would be my second favourite next to Sansa's.

The only excuse for her horrendous behaviour.
