Sonic and you were casually talking before you gently rested you hand on his shoulder. He looked at you confused, until he heard you mumbled something

"I'm sorry..."

he gasped slightly when he felt a huge shock and fell in your arms...

Meanwhile in Sonic's head...

a Sonic like was watching carefully He looked exactly like sonic but his eyes were full black and his pupils were a magenta pink.

"So this is his friend, huh. Surprised they knew how to wake me up..." it said to itself
