The Reality of Immortality

So, Sonic and his friends all live their lives as usual. Whenever Eggman would attack, Sonic would save the day and always be the hero. And so it went on and on as they all moved on in life, with Shadow still being young as usual. Everyone moved on in life....until they all grew old and aged, and then began gradually passing away, leaving young Shadow behind.

The last to leave was Cream and she left, Shadow couldn't take the pain anymore. He hibernated himself for another 50 years. Will he find a new life to live once he has awaken once more, or will he continue to live his immortal life of loneliness?
