Ghost was a single father. He had his daughter on the weekends but he never allowed her to enter the base. This weekend was going to be the same but Price needed him to train the new recruits. So he had to bring his daughter inside the base. He brought her to the mess hall with the rest of the team, which included you. "Hey guys. this is my daughter, Rylee." He pointed to the small girl standing next to him. She was looking at you, not even interested in the rest of the team.
