And Nona didn't belong--doubly. She couldn't be called normal, and she wasn't a repair job as the other accidentals were. Looked at closely she was an original as far from the average in one direction as Anti was in the other. "What's she staring at?" asked Anti as the others slipped past her into the compartment. "Is there something wrong with the little dial?" "That dial has a curious history," said Docchi. "It's not useless, it just isn't used. Actually it's an indicator for the gravity drive which at one time was considered fairly promising. It hasn't been removed because it might come in handy during an extreme emergency." "But all that extra weight----" "There's no weight, Anti. The gravity drive is run from the same generator that supplies passenger gravity. It's very interesting that Nona should spot it at once. I'm certain she's never been in a control room before and yet she went straight to it. She may even have some inkling of what it's for." Anti dismissed the intellectual feat. "Well, why are you waiting here? You know she can't hear us. Go stand in front of her." "How do I get there?" Docchi had risen a few inches now that Jordan had released his grip. He was free floating and helpless, sort of a plankton of space. "A good engineer would have sense to put on magnetics. Nona did." Anti grasped his jacket. How she was able to move was uncertain. The tissues that surrounded the woman were too vast to permit the perception of individual motions. Nevertheless she proceeded to the center of the compartment and with her came Docchi. Nona turned before they reached her. "My poor boy," sighed Anti. "If you're trying to conceal your emotions, that's a very bad job. Anyway, stop glowing like a rainbow and say something." It was one time Anti missed. He almost _did_ feel that way and maybe if she weren't so competent in his own specialty he might have. It was irritating to study and work for so many years as he had--and then to be completely outclassed by someone who did neither, to whom certain kinds of knowledge came so easily it seemed to be inborn. She was attractive but for him something was missing. "Hello," he said lamely. Nona smiled at him though it was Anti she went to. "No, not too close, child. Don't touch the surgery robe unless you want your pretty face to peel off when you're not looking." Nona stopped; she was close but she may as well have been miles away. She said nothing. Anti shook her head hopelessly. "I wish she'd learn to read lips or at least recognize words. What can you say to her?" "She knows facial expressions and actions, I think," said Docchi. "She's pretty good at emotions too. She falls down when it comes to words. I don't think she knows there is such a thing." "Then how does she think?" asked Anti, and answered her own question. "Maybe she doesn't."
