"Me, I feel great. Hungry, though. What's for chow?" Anderson said quickly, "Nick doesn't want us to eat just now." "Thanks," muttered Paresi in vicious irony. "He's the doctor," said Ives good-naturedly. "But don't put it off too long, huh? This furnace needs stoking." He fisted his huge chest. "Well, this is encouraging," said Paresi. "It certainly is," said the Captain. "Maybe the breaking point is just the point of impact. After that the rebound, hm?" Paresi shook his head. "Breaking means breaking. Sometimes things just don't break." "Got to pass," said a voice. Johnny, the pilot, was stirring. "Ha!" Anderson's voice was exultant. "Here comes another one!" "How sure are you of that?" asked the doctor. To Johnny, he called, "Hiya, John?" "I got to pass," said Johnny worriedly. He swung his feet to the deck. "You see," he said earnestly, "being the head of your class doesn't make it any easier. You've got to keep that and pass the examinations too. You've got two jobs. Now, the guy who stands fourth, say--he has only one job to do." Anderson turned a blank face to Paresi, who made a silencing gesture. Johnny put his head in his hands and said, "When one variable varies directly as another, two pairs of their corresponding values are in proportion." He looked up. "That's supposed to be the keystone of all vector analysis, the man says, and you don't get to be a pilot without vector analysis. And it makes no sense to me. What am I going to do?" "Get some shuteye," said Paresi immediately. "You've been studying too hard. It'll make more sense to you in the morning." Johnny grinned and yawned at the same time, the worried wrinkles smoothing out. "Now that was a real educational remark, Martin, old chap," he said. He lay down and stretched luxuriously. "_That_ I can understand. You may wear my famous maroon zipsuit." He turned his face away and was instantly asleep. "Who the hell is Martin?" Ives demanded. "Martin who?" "Shh. Probably his roommate in pre-pilot school." Anderson gaped. "You mean he's back in school?" "Doesn't it figure?" said Paresi sadly. "I told you that this situation is intolerable to him. If he can't escape in space, he'll escape in time. He hasn't the imagination to go forward, so he goes backward." Something scuttled across the floor. Ives whipped his feet off the floor and sat like some cartoon of a Buddha, clutching his ankles. "What in God's name was that?" "I didn't see anything," said Paresi. The Captain demanded, "What was it?" From the shadows, Hoskins said, "A mouse." "Nonsense." "I can't stand things that scuttle and slither and crawl," said Ives. His voice was suddenly womanish. "Don't let anything like that in here!" From the quarters aft came a faint scratching, a squeak. Ives turned pale. His wattles quivered. "Snap out of it, Ives," said Paresi coldly. "There isn't so much as a microbe on this ship that I haven't inventoried. Don't sit there like little Miss Muffet."
