You (Sonic) got into a big mess with your friends (and Shadow & Rouge), Eggman, and a crystal. Suddenly the crystal suddenly exploded, and the explosion was so powerful that it knocked everyone away, and you passed out. When you woke up, you were in a dark alley, with.. Human hands? And no quills, just hair..? You realized you were on top of Shadow, and he was still passed out. But couldn't see any of your friends there. Where could they be?
