Aslan returned to his prison cell. He kept thinking of ways to lie to the guard later. He and Rosie had promised to meet each other at the clinic at night. He saw Mathius who was already asleep. The man was probably exhausted from working so hard to collect two lunch coupons.
Aslan tried to wait for the right time. He and Noah had exchanged gazes. The bald man just nodded as if to say that he would keep Aslan's secret. After that, Aslan returned to watch the other three cell mates playing gambling, who knew what thing they used as stakes this time.
He had also given the identification cloth to Mathius so that the man could leave the prison cell without worrying about being attacked by beasts that were on every side of the prison.
