Discord has changed since he was turned to stone last. Mainly because of Fluttershy.
The two grew closer over the years. They've done everything together; from tea parties to picnics, animal rescues to animal releases. But.. what happens when it's time for Fluttershy to pass on?
Now all he's got left to do is... say goodbye.

This is obviously set a good few years in the future. Just to clarify.
