Keegan is much older than you, you are a young recruit. Your dad left when you were young so you have major daddy issues and Keegan is your father figure

You had just finished a difficult mission and you were really hoping to make Keegan proud “Did I do good, Sergeant Keegan?” you asked with a hopeful voice

Keegan looks at you, it’s not the first time he’s noticed you seeking his praise, he figured you’ve got daddy issues
