The Scooby Gang jumps into a car and drives towards the reported Scarface sighting. They aren't quite sure how to approach the killer because they will fall under his spell if they get too close. Walter theorizes that Olivia might not be affected because she was also treated with the drug and thus might be immune. Peter doesn't think Walter is telling them everything, and Walter agrees. When they reach the building, a cop stops them at the door. He says they don't want to go up there because he doesn't know what's going on up there, but he sent a guy up and now he is standing on the ledge, too. Olivia swears she is going to be okay, shakes off Peter's warning hand, and heads inside. On the roof, all the people Scarface had following him are lining the roof, peering down, poised to fall. Olivia surveys the scene calmly (again with the no swearing!) and looks for Scarface. She approaches him slowly and when he hears her voice he turns around with a huge smile on his face, so happy to see her. He can't believe she's here, and reminds her that she was always the strong one who made him feel better when he was scared. Olivia doesn't remember and Scarface says that is okay because they were supposed to forget. He tells her that he tried really hard to do everything they asked. He stayed fit, he wore black and grey, he stayed alert, he blended in, but the call to be a super soldier never came. Then the man came to the hospital and said they were ready for him and he knew the words to wake up his inner soldier. Now he is wracked with guilt -- he wants to stop hurting people, but doesn't know how. He pulls out a gun, not to shoot, but so Olivia can shoot him. She won't do it. He makes an angry face and some poor schlub in a trench coat falls to his death. He lands on a car next to Walter and Peter. Walter pauses his conversation long enough to hope that Agent Dunham meant to do that. Sometimes this show is really well written. I mean, that was funny! Up on the roof, Scarface tells Olivia that if she doesn't shoot him he will jump and all the unfortunate souls will follow. Did I mention that Scarface keeps calling her Olive? I'm not sure what it means, but Scarface keeps begging Olive to shoot him. He swears that she was meant for that job. Olivia looks at all the people, apologizes to him, and shoots him. In the leg! D'oh! Everyone collapses. They all manage to gracefully fall away from the edge, preventing any further property damage. Scarface tells Olive he wishes that she had really shot him.
