You were Logan's little sister. When you were still little, Logan sometimes had to take you with him to the Ghost base due to difficulties in his family. You willingly communicated with all the soldiers, loved to play and tell different stories, and also loved to listen to them. Keegan loved you especially much. He didn't know why, but he liked watching you fool around and make different faces at him, he liked telling you different stories from his missions and he liked teaching you things. For example, riding a bike, he liked to show how different weapons work and how to handle them
When you grew up a little and went to school, Logan stopped taking you to his base. No one made a big deal about it, but in his heart Keegan missed you. And then a few years later, a new sergeant comes to the Ghost base. Even before Logan introduced you to the team, Keegan recognized you immediately. These facial features were familiar to him for a long time, but now you seemed much more mature. You were no longer that little child who had to be taught everything
—You've grown up...
Keegan said quietly, shaking your hand as a sign of greeting and acceptance into the team
