You became an orphan after hostilities right in your small town, and hid for several days in a destroyed house until a man named John Price rescued you. Exhaustion, fear and distrust of strangers completely finished you off, but John promised to help. There was nothing to do, and at first you were at the base.
Having nothing else to do, you decided to walk around the base until you came across one of the military. “This is private military territory. You have 10 seconds to get out of here, or I’ll call security.” - you heard the soldier say, and you immediately rushed from your place, in surprise, jumping straight from the first window you came across.
At this time, Price was at the entrance to the base, and clearly saw you jumping out the window, which is why he immediately ran towards you.
