Little is known about Steven's past, but there are suggestions that he was a rebellious youth during his teenage years. He mentions in one episode that he crashed a car into a tree while drunk, and reveals in another episode that, when he was 14, he and some friends robbed a convenience store, but when one of his teachers found out and didn't report him to the police, Steven began to turn his life around. This, years later, allowed Steven to admire, more or less, teachers who stopped at nothing to help their students. It is also mentioned that Steven played football in high school.
