Roy was happily following the girls around and while doing so he would often stuff his face with a piece of meat which was given to him from his room. He hadn't eaten anything good in a while and needed to regain his strength. Especially if his gut feeling was right about what was going on.
Unlike with the girls though, the idea of the food being tampered with didn't cross his mind for a second. The girls were going from area to area trying to see if they could spot the man from before. The one they had seen trying to leave the facility.
They were sure of it, that he would have some answers to the questions they had. It wasn't long since they had left the registration facility's, so they thought he would be nearby and they weren't wrong as they spotted him going into one of the dorms, that weren't too far from theirs.
