Princess Celestia, in her infinite wisdom, sent Twilight Sparkle to Ponyville in order to learn about the Magic of Friendship; many years later, and after hundreds of adventures with the five amazing friends she made that day, she now stands watch over the last of them as they prepare for the end. Naturally, they refuse to go quietly into that good night.

After all, there's always time for one last spin around Equestria, right?

The right thing to do and the best thing to do are sometimes mutually-exclusive; when Fluttershy finds the deposed Chrysalis injured and near-death in the Everfree Forest, she knows that the wisest course of action to pursue would be to leave her to her fate. She's a sworn enemy of ponykind, after all, and will only seek to hurt them further once she's rehabilitated.

One's true nature can never be changed, can it?
