Having received an anonymous tip from Janine about an unauthorized building extension to the Optimology building, he is sent by city council to investigate. He calls ahead and sets up an appointment with Mr. Garot to inspect the building. Upon arriving, Theo is knocked down an empty elevator shaft after he refuses to come back another time.
