I found something very weird interesting. There is this old grandpa in the pokemon center in Lapis Ward who tells you a story. It is about a guy who was battling Shade all the time, the frantic soul, Savage, as the people called him. Eventually he beat Shade but he didn't turn back to normal. He also said that he might be still challenging the leage, which implies that we will be introduced to this character later on? This is actually a very good way to foreshadow his appearance in the plot (if he is in the game, and if he will be useful in any way to the story).
