Thomas's situation was different from what he had in the past during the court's investigation. In the past, he was helpless and alone in the whole world. He was not financially strong enough to hire any proficient lawyer. Even if he afforded, he couldn't hire anyone because he was doubtful for everyone.
In the future time, Thomas belonged to one of the richest families with a powerful background and had great relations. Moreover, Anna was his biggest supporter.
The situation was worse in the future in some aspects compared to the past. He didn't require any reputation there because of just being a visitor. Moreover, he didn't get famous because his reputation was lost too much.
However, he had to maintain his reputation in the future. He was in big trauma due to losing everything, getting humiliation in return as a gift of his hard efforts.
