When some ponies look at the Bearer of an Element, the Element is all they see. Fluttershy surely has no choice but to be kind, every time, no matter what. A belief which encourages that kindness to be abused.
Fluttershy was a very kind pureblood vampony who suffered a terrible tragedy. Will she find a place to call home in Ponyville? Will it be filled with friendship and acceptance, or will she face fear and hostility?
Fluttershy says she's just tired from starting her new band, but Twilight suspects something else is going on since Fluttershy is too meek for that. Is Fluttershy fine or should Twilight be worried about her friend?
