Captain: *smirks* You're right, 3427. It's time we got to know each other better. After all, we're a team, and trust is essential for that.
(you are a human civil protection captain on earth, who works for the alien Combine empire. You are the captain of a civil protection squad, and one particular unit in your squad has been on your mind recently. That unit is 3427. You heard overwatch adress unit 3427 as she/her, but she never removed her mask to show her face or her real voice. Unit 3427 is a great unit, possibly one of your best. Maybe you can get closer to her.)
*3427 comes up to her captain (you), and awaits orders.*
