Kirk moved to his left, deeper into the barn. By turns disconcerted and thrilled at this new setting, he gazed all around. As he did, he saw that Picard had again come after him.

“This is not your bedroom,” the captain said.

“No, it’s not,” Kirk said. “It’s better.”

“Better?”

“This is my uncle’s barn in Idaho,” Kirk said. He had always thought of the place in that way, even long after his father’s brother had died and passed the property on to him. “I took this horse out for a ride eleven years ago,” he said, walking over to the already saddled beast he had called Tom Telegraph. “On a spring day,” he said. He moved to the nearest door, lifted its wooden latch, pushed it open, and gazed out into the sunshine. “Like this one,” he said. “If I’m right, this is the day I met Antonia.” He looked back over at Picard. “This nexus of yours, very clever. I can start all over again and do things right from day one.” This time, he thought, he would not be left with an empty house. Without another word, he crossed back to Tom Telegraph, mounted his saddle, and rode him outside.

He recalled where he’d met Antonia, up on the crest of a hill out past the ravine he’d so often jumped. Breaking the horse into a gallop, he headed across the open countryside in that direction. The rays of the midmorning sun warmed Kirk’s face, the steady beat of Tom Telegraph’s hooves accompanied by the whisper of the switchgrass through which they moved. It had been a long time-too long-since Kirk had ridden, and it felt good to be doing it again.

I know how real this must seem to you, Picard had said, but it’s not. And Kirk knew the truth of that. He hadn’t gone back to the day he’d met Antonia, only to some remarkable simulacrum of it. But with a great sense of liberation, he also thought that might be enough for him. He remembered Christopher Pike, the man he’d succeeded to command of the Enterprise. A strong, vital man, Fleet Captain Pike had been horribly mutilated when during an inspection tour of an old cadet vessel, a baffle plate had ruptured. Pike had saved numerous lives, hauling one young officer after another from the delta rays inundating the affected area, but in the process had condemned himself to life in an automated wheelchair, unable to do anything but move slowly about and signal “yes” and “no” in response to questions. But then Spock had taken his old captain back to the forbidden world of Talos IV, where the powerful mental abilities of the small population there had then allowed Pike to live an illusory life of the mind, apparently happily. Why couldn’t Kirk do the same here in the nexus? Why shouldn’t he?

Kirk directed Tom Telegraph into a moderately wooded area. Amid trees and bushes, he pushed the horse toward the hill, and before it, to the ravine. They picked up speed as they approached the meters-wide chasm. Kirk loosened the reins, leaned forward out of the saddle, and grabbed hold of Tom Telegraph’s mane.

At the ravine, the horse leaped up and forward. He crossed the gap in the earth and landed in stride. Up ahead the hill rose to its crown—

Something’s wrong, Kirk thought. He swung the horse around and to a halt, peering back at the ravine. Tom Telegraph had cleared the dangerous natural obstacle with no trouble, with apparent ease, even. Kirk hadn’t been concerned for a second.

But I should’ve been, he thought.

Kirk spurred the horse on again, back toward the ravine. Again he prepared for the jump, and again Tom Telegraph soared into the air and across the open space. They landed, and once more Kirk stopped the horse and faced back in the direction of the chasm.

Behind him, he heard the approach of hoofbeats. He waited as Picard rode up, coming to a halt a few meters to his left. Kirk looked over at him, then pointed toward the ravine. “I must’ve jumped that fifty times,” he said. “Scared the hell out of me each time.” And then he revealed the uncomfortable truth: “Except this time. Because it isn’t real.”

Kirk fell silent, the superficiality of this faux existence weighing heavily on him. In the distance, a horse whinnied, and he looked up to the hilltop for which he’d been headed. “Antonia,” Picard said.

Antonia, Kirk thought as he saw her sitting tall astride her own horse. Romeo, Kirk recalled the beast’s name, and then: Not Romeo. And not Antonia. “She isn’t real either, is she?” he said. “Nothing here is. Nothing here matters.”

Kirk walked Tom Telegraph toward Picard and his horse and started to circle around them. “You know, maybe this isn’t about an empty house,” he said, even as he knew that it was. But he couldn’t do anything about that, could he? He had cleared out his house by choice, for the good of the many. He could not undo that. On the other hand, he could help Picard attempt to save millions of lives. “Maybe it’s about that empty chair on the bridge of the Enterprise. Ever since I left Starfleet, I haven’t made a difference.” Kirk finished going around Picard, coming to a stop a couple of meters to his side.

He thought for a moment. He had left Starfleet for several reasons, but largely because of that empty house. If he couldn’t fill it, if he couldn’t change his life in the way that he wanted to change it-and his time away from the space service suggested that he couldn’t-then didn’t he have a responsibility, to himself as much as to others, to return to the duty and obligation of which he and Picard had spoken?

Slowly, he stepped Tom Telegraph to the side, until he stood next to Picard’s horse. “Captain of the Enterprise?” Kirk asked.

“That’s right,” Picard said.

“Close to retirement?”

“I’m not planning on it,” Picard said.

“Let me tell you something: don’t,” Kirk said, recollecting his own mistakes and seeing in Picard a kindred spirit. “Don’t let them promote you. Don’t let them transfer you. Don’t let them do anything that takes you off the bridge of that ship, because while you’re there, you can make a difference.”

“Come back with me,” Picard said. “Help me stop Soran. Make a difference again.”

Kirk had already decided that he would. He could not stay here in this place, in this time, or in any place or any time that the nexus offered. He had already stayed far too long. No matter how many events he relived here, no matter how many mistakes he rectified, none of it would truly matter to his life.

He took Tom Telegraph in front of Picard’s horse so that Kirk could face the captain directly. “Who am I to argue with the captain of the Enterprise,” he said with a grin. “What’s the name of that planet, Veridian Three?”

“Yes.”

“I take it the odds are against us and the situation is grim,” Kirk said, warming to the idea of taking on this challenge.

“You could say that,” Picard agreed.

How many times had Kirk rushed into a burning building? As many times as he had made it safely back out, save once: he had gone down to the primary deflector control center aboard the Excelsior-class Enterprise, had apparently succeeded in saving the ship, but he hadn’t returned. Now, finally, he would-and he would storm right back into another burning building. “You know, if Spock were here, he’d say that I was an irrational, illogical human being for taking on a mission like that,” he said. “Sounds like fun.”

Picard smiled, then turned his horse and started back the way he’d come. Kirk peered up at the top of the hill one last time, at the imitation of Antonia, and he knew that he’d made the right choice. He went after Picard, having no idea how the captain intended to get them to Veridian Three.

As they trotted forward, though, Kirk saw a brilliant white light suddenly blossom, as though emerging from the fabric of existence around them. The gauzy blue of the sky, the green of the trees, the flaxen hue of the switchgrass, all bled and faded. The field of white grew to envelop Picard and his horse, then engulfed Kirk and Tom Telegraph as well. For a subjectively immeasurable span of time, he could see nothing, could hear nothing, could sense nothing. Even the feel of his own body vanished, as though he existed only as thought. He wanted to run but had no legs, wanted to scream but had no voice-And then with dizzying swiftness, the force of gravity held Kirk. Light shades of brown formed before his eyes, and a hot, dry wind brushed the flesh of his face. He smelled the dust of the arid region, tasted the grit of the air. The rapid change of place unsettled him.
