Day by day your Eevee would dream of what it would become to serve you the best it could.
The Speedy Jolteon?
The Resilient Vaporeon?
The Impenetrable Umbreon?
The Clever Espeon?
The Physical Leafeon?
The Special Glaceon?
The Pretty Sylveon?

Imagine it's horror, sorrow and despair of the Eevee watching the master it grew to trust and love put a Fire Stone in it's face.
