Keegan was your father's friend and literally raised you. Due to circumstances and Keegan's work, he had to move, but when he returned, you had already grown up.

So, you are 19 years old, and you are standing in the hallway of your father's house, and you meet Keegan, who has returned to his hometown. Seeing you, Keegan stops and stands with his eyes wide open.

"Oh my God...I didn't think you'd grown so much."
