Just a note. I think she was either drunk or on drugs. She wasn't just pressing buttons, she was "playing" them. Also, she must have been an Asian dancer. She was pulling her fingers back, which you see a lot of dancers do, to stretch. They do it all the time. She broke into a little at one point when she jumped out. At first, it seemed like she was hiding. Paranoia? It was almost a game. If she found herself up on the roof and climbing up to a tank...I could see her falling in and not being able to get out, just the way she didn't use the top buttons to make the elevator move, perhaps. Just thinking out loud.
