A Welcoming Colleague
Engineering conversation
Chuck Freudenberg becomes one of the few people at Hired Girl who enjoys discussing engineering for its own sake. He offers Dan corrections and context as Dan catches up on thirty years of technical progress.
Respect without spectacle
Chuck's interest in Dan is not limited to his status as a Sleeper. Their friendship grows through practical criticism and shared curiosity rather than public fascination.
A Warning About Work

A Warning About Work
Protecting new ideas
When Dan describes his automatic secretary design, Chuck warns him to check his employment status before developing it on company time. He believes the idea can work and wants Dan to retain control of it.
Advice from loyalty
The warning is direct, not self-serving. Chuck recognizes that the company may claim an invention Dan never agreed to give it and helps him avoid repeating the mistakes of his earlier partnership.
A Disturbing Patent

A Disturbing Patent
Dan's fear of amnesia
Dan shows Chuck patents for Eager Beaver and Drafting Dan and worries that the matching inventor name means his memory has failed. The question unsettles him more than the commercial history of the inventions.
A calm counterargument
Chuck points out that another D. B. Davis could exist and that improbable coincidences are not impossible. He helps Dan test an explanation instead of reinforcing his panic.
A Secret Disclosed

A Secret Disclosed
Time travel mentioned
Chuck explains the classified temporal experiments he encountered as a student. He emphasizes their uncertainty, expense, and lack of a reliable way to select direction or return.
A friend listens
Dan is tempted by the chance to investigate the past, while Chuck tries to restrain him. He ultimately gives Dan enough information to make an informed choice, despite the risk to his own classified status.
A Promise to Look Further

A Promise to Look Further
A safer inquiry
Chuck offers to ask Aladdin's chief engineer about the identity behind the patent, giving Dan a lower-risk route than temporal displacement. Their ordinary professional network could resolve the problem without a dangerous experiment.
Friendship under strain
Dan nevertheless follows the temporal lead, but Chuck remains the confidant who helps him think clearly. Their relationship is defined by frank disagreement rather than unquestioning agreement.
