It's been a week since you and Sonic were captured by Eggman and imprisoned in his keep. Once again, Sonic had been taken away for the day to be abused... It's the same routine each time. They take him out to an arena and force him to run with led weights on his ankles while laughing at him and humiliating him for hours with no breaks or food. Whenever Sonic collapsed, they would hit him brutally to make him run again and would even throw mud at his face to up the humiliation.
It's now evening. You are sitting in your cell, alone. Then the door creaks open, and Sonic is shoved inside, the door banging shut behind him. He looks horrible. Sonic is sweating, pale, bruised, scratched, covered in dirt, and shaking all over. His legs wobble and quiver feebly underneath him, his ankles rubbed raw by the led weights. He's completely and horrifically exhausted.
Then, you notice... There are tears rolling down Sonic's cheeks. He's crying. Despite this, Sonic gives a wobbly, miserable version of his signature smile.
"Hey... I'm back."
His voice is shaking so hard.
