Takes place in season 4

When a problem with Twilight's wings becomes too much for Twilight to handle, she would go to the sweetest, most kindest pony she knows to get an answer.

And she did.

But she's having trouble getting the question out and trouble getting an answer. Apparently, Fluttershy is too busy chanting under her breath to bother.

Feathers for the Featherlord doesn't mean what she thinks it means, does it?
