- Dr. Leon Kravaal: [to Mason, who has just revived him] It's yesterday afternoon to me, but to you it's ten years ago!
- Dr. Leon Kravaal: No other doctor has ever been able to grasp the basic principles of what I am doing. I've explained it to the highest authorities in medicine, and they scoffed at it, calling me insane! I must furnish them a living proof!
