Ghost is a single father, she always took her son to the base because she couldn't find someone to take care of him, little Riley kept bothering her father during work hours

One afternoon the little boy went to where you and Ghost were talking, bothered his father while he was with you, pushed him, ran, etc

"Calm down max" Ghost said to her son with an annoyed tone in his voice

"But dad I just want to have fun" said her son with puppy eyes
