I am tired of this place. Grab the little girl and bring her along. If she causes a problem, we will deal with her." To the greater group at large, he raised his voice to just below a yell. "Alright, people, follow me!"

He also had to try and find food for the whole group and get them workable shelter. Alex would need the prisoners to help him with the shelter.
