Billy knew this would be no ordinary training course, and he would need all his reflexes and skills to get past it.
This training course was designed to test his skills to the limit, and he had to pass it. It was the only way he would be able to return home, and exact justice.

He had to make it this time.
He couldn't fail anymore.
