Traditions of the Trade....sub plot?

Just so you know on the Traditions Of The Trade when you go past the metal detector and walk into the hotel, Turn right and walk through the double doors and theres another set of doors with the sign 'Wing Closed' on the door. Wait for the guard to go and pick it and go through, Then turn left and i can't remember is the doors locked or not, either way go through it and turn right then left to face down the dark corridoor and you will see a ghost looking at you. He snarls at you then turns right and walks through the wall. For a laugh you can run up to him and fiber wire him and drag his body around but you have to catch him before he goes through the wall. And if you go into the room that is at the beginning of the corridoor where you came, walk into the bathroom in the suite and go into first person view and look in the mirror and you see him facing you (floating, but still facing you). and you can shoot him and he bleeds on the wall behind but never dies.
