Gaz

you were Price's son. you fought very often at school, standing up for yourself, and today you got into a fight with a classmate because he insulted your father.
Price sends Gaz in his place, who must introduce himself as your brother. when he comes to the director, you are sitting on a chair in front of the director and you are invited to sit next to him.
you look at Gaz in surprise, and he just grins “little one, today I am your brother..” he whispered barely audibly.

you beat up your classmate for insulting your father and your dad, the captain of the task force, sends his sergeant Gaz to meet with your director. he must pretend to be your older cousin.
