Paresi said, "You can't conclude that, Ives. They've inconvenienced us.

They've turned us in on ourselves, and put a drain on our intangible resources as men and as a crew. But so far they haven't actually done anything to us. We've done it to ourselves."

Ives looked at him scornfully. "We wrecked the unwreckable controls, manufactured that case-hardened darkness, and talked to ourselves on an all-wave carrier with no source, about information no outsider could get?"

"I didn't say any of that." Paresi paused to choose words. "Of course they're responsible for these phenomena. But the phenomena haven't hurt us. Our reactions to the phenomena are what has done the damage."

"A fall never hurt anyone, they told me when I was a kid," said Ives pugnaciously. "It's the sudden stop."

Paresi dismissed the remark with a shrug. "I still say that while we have been astonished, frightened, puzzled and frustrated, we have not been seriously threatened. Our water and food and air are virtually unlimited. Our ability to live with one another under emergency situations has been tested to a fare-thee-well, and all we have to do is recognize the emergency as such and that ability will rise to optimum."

He smiled suddenly. "It could be worse, Ives."

"I suppose it could," said Ives. "That blackness could move in until it really crowded us, or--"

Very quietly Hoskins said, "It _is_ moving in."

Captain Anderson shook his head. "No...." And hearing him, they slowly recognized that the syllable was not a denial, but an exclamation. For the darkness was no longer a half-meter deep on the bulkhead. No one had noticed it, but they suddenly became aware that the almost-square cabin was now definitely rectangular, with the familiar controls, the communications wall, and the thwartship part.i.tion aft of them forming three sides to the encroaching fourth.

Ives rose shaking and round-eyed from his chair. He made an unspellable animal sound and rushed at the blackness. Paresi leaped for him, but not fast enough. Ives collided sickeningly against the strange jet surface and fell. He fell ma.s.sively, gracelessly, not p.r.o.ne but on wide-spread knees, with his arms crumpled beneath him and the side of his face on the deck. He stayed there, quite unconscious, a gross caricature of worship.

There was a furiously active, silent moment while Paresi turned the fat man over on his back, ran skilled fingers over his bleeding face, his chest, back to the carotid area of his neck. "He's all right," said Paresi, still working; then, as if to keep his mind going with words to avoid conjecture, he went on didactically, "This is the other fear reaction. Johnny's was 'flight.' Ives' is 'fight.' The empirical result is very much the same."

"I thought," said Hoskins dryly, "that fight and flight were survival reactions."

Paresi stood up. "Why, they are. In the last a.n.a.lysis, so is suicide."

"I'll think about that," said Hoskins softly.

"Paresi!" spat Anderson. "Medic or no, you'll watch your mouth!"

"Sorry, Captain. That _was_ panic seed. Hoskins--"

"Don't explain it to me," said the engineer mildly. "I know what you meant. Suicide's the direct product of survival compulsions--drives that try to save something, just as fight and flight are efforts to save something. I don't think you need worry; immolation doesn't tempt me.

I'm too--too interested in what goes on. What are you going to do about Ives?"

"Bunk him, I guess, and stand by to fix up that headache he'll wake up to. Give me a hand, will you?"

Hoskins went to the bulkhead and dropped a second acceleration couch. It took all three of them, working hard, to lift Ives' great bulk up to it.

Paresi opened the first-aid kit clamped under the control console and went to the unconscious man. The Captain cast about him for something to do, something to say, and apparently found it. "Hoskins!"

"Aye."

"Do you usually think better on an empty stomach?"

"Not me."

"I never have either."

Hoskins smiled. "I can take a hint. I'll ra.s.sle up something hot and filling."

"Good man," said the Captain, as Hoskins disappeared toward the after quarters. Anderson walked over to the doctor and stood watching him clean up the abraded bruise on Ives' forehead.

Paresi, without looking up, said, "You'd better say it, whatever it is.

Get it out."

Anderson half-chuckled. "You psychic?"

Paresi shot him a glance. "Depends. If you mean has a natural sensitivity to the tension spectra coupled itself with some years of practice in observing people--then yes. What's on your mind?"

Anderson said nothing for a long time. It was as if he were waiting for a question, a single prod from Paresi. But Paresi wouldn't give it.

Paresi waited, just waited, with his dark face turned away, not helping, not pushing, not doing a single thing to modify the pressure that churned about in the Captain.

"All right," said the Captain irritably. "I'll tell you."

Paresi took tweezers, a retractor, two scalpels and a hypodermic case out of the kit and laid them in a neat row on the bunk. He then picked up each one and returned it to the kit. When he had quite finished Anderson said, "I was wondering, _who's next?_"

Paresi nodded and shut the kit with a sharp click. He looked up at the Captain and nodded again. "Why does it have to be you?" he asked.

"I didn't say it would be me!" said the Captain sharply.

"Didn't you?" When the Captain had no answer, Paresi asked him, "Then why wonder about a thing like that?"

"Oh ... I see what you mean. When you start to be afraid, you start to be unsure--not of anyone else's weaknesses, but of your own. That what you mean?"

"Yup." His dark-framed grin flashed suddenly. "But you're not afraid, Cap'n."

"The h.e.l.l I'm not."

Paresi shook his head. "Johnny was afraid, and fled. Ives was afraid, and fought. There's only one fear that's a real fear, and that's the one that brings you to your breaking point. Any other fear is small potatoes compared with a terror like that. Small enough so no one but me has to worry about it."

"Why you, then?"

Paresi swatted the first-aid kit as he carried it back to its clamp.

"I'm the M. O., remember? Symptoms are my business. Let me watch 'em, Captain. Give me orders, but don't crowd me in my specialty."

"You're insubordinate, Paresi," said Anderson, "and you're a great comfort." His slight smile faded, and horizontal furrows appeared over his eyes. "Tell me why I had that nasty little phase of doubt about myself."

"You think I can?"

"Yes." He was certain.

"That's half the reason. The other half is Hoskins."

"What are you talking about?"

"Johnny broke. Ives broke. Your question was, 'who's next?' You doubt that it will be me, because I'm _de facto_ the boy with all the answers.
