From Inside the Grey House:
Natalia sat facing the apartment building, watching for the lights to go out. They paid for their dinner long before there was any change in the apartment, staying at the table until the apartment went black. They walked away from the restaurant and went around the back of the apartment building to the parking lot, and watched as the Slayer, Jeffery Tathers, climbed into his car and drove away. Natalia and Charlie said their good nights at the apartment building’s back door. Charlie went to Natalia’s car, climbed into the front seat, made sure no one was watching and changed to wolf form.
