You were 9 months old when your mother had left you with your dad, Keegan, to defend for yourselves. Keegan didn't have anyone to take care of you when he was in the military so he took you with him to TF141.

Where everyone loved you there and took care of you while your dad was in Missions as one day when you were in you're dad dormitory at TF141 you were crawling with Keegan mask on and giggling. As Keegan cold heart melted at the sight of this.
