 Marin, I've got a lot of work to clear up this morning. I thought you might like to know where the mice came from. They don't bother us anymore. I've also determined the origin of the rats. They're under control. I wonder if they are, Mr. Hafner. What do you mean? Mr. Hafner, I've checked this with Whitehead. Between 100 million years and 20,000 years ago, this planet was changing violently and quickly. The first change wiped out the dinosaur just the way it did on Earth. But it kept on changing.
