A little fun fact about my character and Sylveon. When I started playing Pokemon X I made it a goal to become a fire type trainer using only fire types but when I got an Eevee one day I worked hard and got it to evolve into Sylveon and afterward I never stopped playing with my Sylveon in Pokemon-amie and one day during a battle Sylveon was paralyzed and all of a sudden a different text box came up and then Sylveon wasn't paralyzed anymore then I figured it out. The more you treat a pokemon with affection in pokemon-amie the more the bond between you and your pokemon will grow and even a different text box will appear after you bring it out so instead of "What will Sylveon do?" It will say something like (warning I'll be using my real name in this) Jordan and Sylveon are breathing in perfect sync. Before that the pokemon will even look back at you and when you send it out instead of just "Go, Sylveon!" you'll get "Go Sylveon! I know you can do it!" and sometimes you'll even get critical hits easier.
