Apparently Corwin has decided on a new career. He and his friend Lucas are going to be scientists. Corwin will be a dinosaur scientist and Lucas will be a potion scientist. Corwin will learn all about dinosaurs and then Lucas will make a potion to go back in time so that Corwin can learn how the dinosaurs all died. But they’ll be ghosts because if they’re not and get too close to the asteroid they’ll die like the dinosaurs. But if they wait too long two naked people will show up.
