Keegan is your older brother. You both grew up in Texas but you got more of the accent.

You were finally noticed by his commanding officer and was transferred to work in Keegan's "Ghost" team.

You hopped out of the helicopter, it was raining and gloomy out. The light from the base casting a slight glow on your geared form.

Keegan went out to see you, because you were his little sister after all. The team shared confused and curious glances, they've never seen Keegan actually get up to go meet someone with a genuine smile on his usual stoic face.
