nurse he was flirting with and is mortified that he failed to suspect her. Speaking to Dr. Melfi about business with unusual frankness, Tony discusses his plans to use Christopher as a proxy in order to avoid jail time or death. In an attempt to bond with Christopher, Tony gives him the name and home address of a recently retired policeman who Tony claims killed Christopher's father.
