In 1969, with the animal testing done, Astrid Pflaume and Kurt Weimer are sent back in time to 1916 in their first journey through time. While they are there, they accidentally kill Lenin, then nervously activate their return trip. They return to their own time, and nothing has been changed. Schoemann postulates that they should be able to return to the changed world they have created because they now have a quantum affinity with it; this will be how they change the world.
