Cain sells a future that has learned from the mistakes of the previous future. His presentations used to concern desalination ventures. Now they concern a more personal form of renewal.
Bring him a failed Second Coming pledge and he can explain how discipline, reserves, and confidence will make it useful again. The kitchens do serve food. A person choosing where to stand in line has reason to notice that before investigating his biography.
He likes a public accounting of other people's promises. His own accounts require a longer appointment.
The stewards keeping his queues in order answer to a quieter man. Cain calls him brother. People listening carefully have noticed that the courtesy is not returned.
