course I’ll try to think of something, but dammitall, this is really a problem in physics — I need Scotty for the whats, hows and whys of the accident to get even a start on it!”
“I was afraid of that,” Kirk said.
“There’s something else you ought to watch out for, though.”
“What’s that?”
“It’s a psychological problem — this business of being identical twins. Even under ordinary, biological circumstances, being an identical twin is a hard row to hoe. You’re constantly having identity trouble; mothers think it’s cute to dress the kids alike, teachers have trouble keeping their records straight, friends can’t tell them apart or think it’s funny to pretend they can’t. It all usually comes to a head in puberty, which is when the who-am-I problem becomes acute for everyone, but for identical twins it’s hell. If they get through that period without becoming neurotic or worse, they’re usually all right from then on.
“But Spock didn’t go through it, and furthermore he has been emotionally isolated almost all his life, by his own choice. Now, suddenly, he has been twinned as an adult, and it’s a situation he has had no chance to adjust to, as the natural twin has. The strain is going to be considerable.”
Kirk spread his hands. “Help him if he’ll let you, of course, Doc, and I’ll try to take it into account myself. But it seems to me that the adjustment is almost wholly something he’ll have to arrive at by himself. And bear in mind that he has had a lifetime of training in controlling his own emotions.”
“Not controlling them — suppressing them,” McCoy said. “The two are very different. But of course he’ll have to handle it by himself. One thing laymen never understand about psychotherapy is that no doctor has ever cured an emotional or mental upset, or ever will; the best he can do is to show the patient how he might cure himself.
“But Jim, don’t minimize this — it’s no small consideration. In my judgment, there’s likely to be a real emotional crisis, and sooner rather than later. I’ve already noticed that one of them’s gone considerably off his feed. Won’t hurt him for a while — Vulcans can fast a long time — but anorexia is almost always the first sign of an emotional upset.”
“Thanks,” Kirk said grimly. “I’ll be on my guard. And in the meantime, let’s see if Scotty’s thought of any tests yet.”
He left the sick bay and went to the engineering bridge.
“Scotty, I hate to keep taxing you with the same old question, but Doc says he can’t get anywhere on setting up a test for the real Spock, or the replicate, until he has at least some sort of idea of how the duplication happened. Any clues yet?”
Scott said miserably, “Ah dinna ken, Captain. Ah dinna oonderstahnd it at all.”
There were blue-black isometric smudges under his eyes, and it was obvious that he had not slept at all since the start of the botched transporter experiment. Kirk stopped pressing him at once; clearly he was doing his best, and his performance wouldn’t be improved by distracting him.
Then everybody, not just Scott, was interrupted by the call to Battle Stations.
Kirk’s immediate assumption — that Uhura’s sensors had picked up something that might be another ship — proved to be true, but he was no sooner on the bridge than he became aware that this was only a small part of the story. For one thing, the automatic drive log on his control console showed that the Enterprise had been off warp flight for a split second before the alarm had sounded. She was now back in subspace, of course, but the trace the sensors had picked up was that of an object so small that if it had really been a Klingon ship it would have been incapable of detecting the Enterprise in subspace over the distance involved.
“What,” Kirk demanded grimly, “were we doing off warp drive?”
“The computer took us off,” Sulu said, with the justifiable irritation of the helmsman who has had control snatched away from him by a brainless mechanism. “It still seems to be operating on the old benchmarking schedule. Maybe in all the subsequent confusion, nobody ever told it we were going to Organia.”
“That’s flatly impossible,” Kirk said. “I logged that order myself. Somebody had to countermand it. Mr. Spock, ask the machine who did.”
The First Officer — it was Spock Two who was on duty — turned to the console, and then said, “The computer reports that I gave the order, Captain, as is only logical. But in point of fact I deny doing so — and I strongly suspect that my counterpart will also deny it.”
“Wipe that order, and see that it stays wiped. Mr. Sulu, put us back on warp drive on the double.”
“Already on, Captain.”
“Mr. Spock, is the computer malfunctioning?”
“No, Captain, it is in perfect order. There is no doubt that one of us did so instruct it. But since such a course clearly involves grave risks of detection by the Klingons, and has no compensatory advantages, it can only have been given because detection was exactly what was hoped for. That is why I conclude that my counterpart will also deny having given it.”
“The argument applies with equal force to you,” Kirk pointed out.
“I am thoroughly aware of that. Unfortunately, however, there is no other reasonable explanation.”
“No time is recorded for the issuance of the order, I suppose.”
“No, which further argues that the issuer wished to remain unknown.”
Kirk thought a moment. “Lieutenant Uhura, any sign that we have in fact been detected?”
“I think so, Captain. If the object has laid any sensors on us, they’re too feeble to register on my board — but it dropped into subspace just after we did, so it can’t be a natural object and may well be following us — though at a very respectful distance.”
“Mr. Sulu, execute some simple, showy evasive maneuvers and see if it follows those. If it does, lose it — or if you can’t lose it, outrun it. It can’t pack enough power to pace us.”
“I’ll lose it,” Sulu promised cheerfully.
“Mr. Spock, you are relieved of all duties. Mr. Sulu is designated first officer pro tern. Lieutenant Uhura, notify all concerned that henceforth and until further notice, orders from either Spock are without authority aboard this ship. We are proceeding to Organia as before, and until I say otherwise; the benchmarking program is cancelled. Any questions?”
There were none.
“Mr. Spock, call your counterpart in your quarters and notify him that we’re both coming to visit him. In the interest of ship’s harmony I’ve been trying to avoid such confrontations, but one of you has driven me to the wall — me, and himself.”
Kirk had not been in the first officer’s quarters since the incident of Spock’s near-marriage on Vulcan itself — the painful episode Kirk had obliquely referred to in his first interview with Spock One, the episode during which an amok Spock had quite seriously tried to kill him. These quarters were very like his own in general plan, but considerably more austere. What little decoration they sported consisted chiefly of a few pieces of cutlery, vaguely and misleadingly Oriental in design, which reminded Kirk that Spock’s parental culture — on his father’s side though now fiercely rationalistic in its biases — had once been almost equally fiercely military.
Kirk was not surprised to notice that the quarters showed not the slightest sign that they were being occupied by two people instead of one. There were two Spocks here now, however, and they were staring at each other with cold but undisguised hostility. The battle had been joined, overtly, at last. Perhaps that was just as well.
“One of you two gentlemen has been uncharacteristically stupid,” Kirk said, “and if I could detect which one it was, I’d fire him out the emergency airlock in his underwear. Wantonly endangering the Enterprise is as serious a crime as violating General Order Number One, as far as I’m concerned — and as you both know very well. So I’m at open war with one of you, and both of you are going to have to suffer for it. Spock One, did you countermand a course order that I’d logged in the computer?”
“No, Captain, certainly not.”
“A routine question. Very well. You are relieved of duty, both of you, and I wish you joy in trying to stay out of each other’s hair in the same quarters with nothing to do. In the meantime, I’ve got no grounds to want to cause either of you selective discomfort, if you know what I mean, and I’ll try to see that I don’t. In return, I want your advice. Spock One, do you agree that whoever had the computer take us off warp drive wanted the Enterprise detected by the Klingons?”
“It seems to be the only possible conclusion,” Spock One said.
“Why did he do it?”
