Scenario: #3 - The Docks
To complete this scenario, go to the office and look at the phone. Go back to Miles whom is on the phone, and talk to him about the passes. When he is talking to the worker, steal the passes. Afterwards you will talk to Miles again and try to get in. The employee will ask you questions on who you are. You can tell him whatever you want, or not even answer at all. When prompted, press to give him an alternate answer (aka your fist).
