Mr. Monk and the Naked Man - S6-E3
Character mistake: SPOILER. Arlene Boras murders Vicki Deline in order to stop her telling Peter Magneri that he has an aortic aneurysm. Boras wants Magneri dead to clean up by short selling the stock in his company. Boras is a medical professional, and she would know that an aneurysm can burst if the patient is under stress or is shocked in some way. Allowing Deline to tell Magneri that he is in danger of dropping dead on the spot would kill him, which is exactly what she wants.
Mr. Monk and the Naked Man - S6-E3
Character mistake: SPOILER ALERT Monk accuses Arlene Boras of swapping Peter Magneri's X-rays in order to hide the fact that he has a potentially lethal aortic aneurysm. We see Magneri being examined and we see Boras handling his records, and they are not X-rays. Magneri was examined in an MRI scanner and Boras swaps the MRI scans - not X-rays.
Answer: The two men are trying to work out a secret deal between them without involving the union, which means the workers' interests aren't being represented and defeats the whole purpose of a union. The mayor would lose labor's support and Cusack's union troubles would just be starting.
