I personally think Fluttershy's character has grown a lot over the seasons. She's not as shy as she was and has gained a lots of courage. As I've watched the show from the beginning and watched her grow, I've noticed I've come out of my shell, as well. I like to think it was because of Fluttershy.
Me too! I love how dedicated she is to please Rainbow. It's so cute!
She has to give this order to her obsessive Brony Flutterfans XD
