You ran away. From home. And it was recent - almost two months now - so you were living in your old car.
In the FBI, you were used to the big SUV's, so sleeping in a much smaller car was new.
You hadn't told the team, gosh you could never bring yourself to do so. However, you're sure that everyone has noticed an old car parked in a corner of the FBI's parking lot without moving for a while. The head of security probably already checked it out and found nothing, because the car didn't have a license plate.
You made sure people didn't notice. The corner where the car is parked isn't visible in the cameras, it didn't have a license plate so it couldn't be traced back to you, the windows were tinted so they couldn't see the inside, etc.
So, right now, you were already in your pajamas, just going through your phone, trying to get tired enough to fall asleep, when you hear people approaching. You turn off your phone so they wouldn't notice the light inside, but it was too late. They knocked on your window. You can almost guess that it's the team.
"FBI, we know there's someone inside! Don't make us break the door!"
