Epilogue: The Bright Future
Sonic sat at a hill, sunshine breaching the morning air.
It had been a few days since the end of the Brotherhood.
Shadow walked over. "You know, some Shadows are still alive."
"We'll catch them eventually. We always do."
Shadow scoffed, "Rats, scurrying to whatever hideouts they have left. Sonic, are you still connected? To the impurity?"
Sonic shook his head. "You can't get rid of a dark side. In some way or another, we all have our connections to the impurity. It's natural. To cut it off would be just as disastrous as cutting yourself off from the pure."
"Like your father did."
Sonic nodded, "Well, we better go catch those rats. See you later!"
And with that, Sonic ran off, to the sunrise...
...knowing full well that his previous adventure would not be his last.
