"Who is this Chloe Sullivan?"

With his question, Colonel O'Neill was not expressing ignorance about Chloe in general. He knew a lot about one Chloe. When he was on the team, Clark talked about his Chloe quite often.

Instead, what the colonel meant, obviously, was what were the particular characteristics of this Chloe Sullivan. The one walking down the corridor with an aged Mister Spock.

"Let's see," Daniel said in a kind of muttering voice. "She's a meteor freak who can absorb the abilities of other people. She put on the Doctor Fate helmet which gave her knowledge of the future so she knew what to do, where to go."

"Must be nice," O'Neill said.

"She came in contact with a Sam Beckett similar to our own. After that, she was able to leap around in time and space. When she met a Spock from another world, she developed the ability to mind-meld. During the Joker crisis, she's been traveling from world to world helping out different teams."

At that, O'Neill's eyebrows went up. "Long way from being editor of the 'Torch.'"

The colonel tuned back in to what Spock was saying.

"I was shown the future both by Miss Sullivan here and our mutual associates, often referred to as the 'Big Bang' guys. After the meteor shower, my wife Cassandra was able to show me other parts of the future."

As Spock explained, he moved rapidly down the corridor of this...Fortress-looking thing, whatever it was. O'Neill observed the Vulcan moved quickly, especially for someone who looked really old.

Spock stopped to speak into an intercom. "Captain MacGyver, you may get underway to our rendezvous with Mister Kent."

"You got it, Spock," came the electronic reply.

As he moved, Spock continued on with his story.

"Knowing the future, I was able to gather the Stones of Knowledge and duplicate them. I then created a duplicate Fortress in Antarctica."

"Which you could call Fortress Spock," Leonard said with a smile.

O'Neill gave him a look. "Thank you, Leonard."

Leonard made a face. "Yeah, sorry. Not really relevant."

Spock continued. "After the meteor shower, I had access to the Jor-El computer program. Just as Clark Kent did in his Fortress. With the arrival of Clark's ship, the program downloaded into both Fortresses. Jor-El and I then turned my duplicate Fortress into a time machine using alien technology provided by the Men In Black."

"Which we then reduced to the size of a crystal," Chloe said. "Makes it handy for traveling."

"Unfortunately, the Fortress time machine has limited power," Spock said.

"Only good for four time-jaunts," Chloe said.

"We needed another way to travel through time," Spock said. "So we used the Stargate in Antactica when it was subject to solar flares."

"Not exactly a way to travel to a precise point in time," Carter said.

"It is when you know the future, Major Carter." For a moment, it was like Spock struggled to collect his thoughts. Then: "You may find this interesting. Through the Antarctica Stargate, we traveled back to the year nineteen-sixty-nine. There, we met Team MacGyver."

"Apparently, that year is some kind of focal point in time," Chloe said.

"We were there building a space-time tunnel," Leonard explained.

"Of course you were," O'Neill said. "That's what you do."

"One team member proved particularly invaluable," Spock said.

"Sheldon performed the necessary calculations so we could access Ba'al's fail-safe device," Chloe said.

As the two explained, images appeared on the walls, bringing their story to life.

Leonard leaned in to whisper to Daniel. "This is like living inside a 'Star Trek' movie."

"Kind of," Daniel said.

"Ba'al once used a Stargate to create an alternate timeline," Spock said. "That may be confusing to you."

"We know a little about our future," Daniel said.

"It's supposed to make things less confusing but it really doesn't," O'Neill said.

"I see, very good," Spock said absently. "Using the space-time tunnel built by Team MacGyver, we arrived at Ba'al's fail-safe. Miss Sullivan and I then accessed the same Stargate Ba'al used for his 'timeline invasion.'."

"That's what I call it," Chloe said with a grin. "But we only went through the Stargate after Cameron Mitchell and the sailors took out Ba'al and his men."

"Smart," O'Neill said.

"That allowed us to set up the Fortress in Antarctica in nineteen-thirty-nine," Chloe said.

"That's all good and fine," Daniel said as he adjusted his glasses. "But we have a problem."

"We need eighty years of rest, Mister Spock," Carter said.

"Otherwise, when we step off this time machine we'll disintegrate," Beckett said.

"Which we'd like to avoid," O'Neill said.

Teal'c nodded. "We would then be unsuccessful in correcting the timeline created by Clark Kent when he saved Edith Keeler."

"The one where you and Captain Kirk lived happily together in Smallville," O'Neill said.

"That sounds cool," Leonard said. "I would live there."

"Maybe not, Leonard," Daniel said. "In that timeline, Lex Luthor becomes a global dictator."

"Oh. Not so cool then," Leonard said.

O'Neill had some sharpness in his voice. "The point is we need eighty years of rest to get off this ship."

"Yes, Colonel O-Neill," Spock said. "That is exactly what I have arranged."

The aged Vulcan opened the door to a room. Inside were red and blue tubes. In those tubes were...

SG-1 and Beckett. Only wrinkled and white-haired.

Spock made a quiet introduction. "S-G-One, meet S-G-One."

"We brought you, a little later you, out of the Phantom Zone," Chloe explained. "We put you in these tubes that slow down aging just a little. After the other you spent eighty years in rest, we went back and got earlier you. That is, you now." She smiled as she held up her hands. "Ah, the wonders of time travel."

"Some travel through time more slowly, Miss Sullivan," Spock noted.

Chloe nodded. "I can leap through time so I didn't age the way Spock did. He stayed with you guys and monitored you the whole time."

It took a while as SG-1 and Beckett struggled to comprehend the situation. Then followed the looks of realization.

Carter wore a slightly wide-eyed look of almost-awe. "You watched over us."

"All those years," Daniel said quietly.

With her bright blue eyes, Carter looked at Spock. "What you did, Mister Spock. It must have been very lonely."

Spock wore his thoughtful narrow-eyes look. "Not as much as you might think, Major Carter. I mind-melded with each one of you, and in our minds we shared various life experiences. Together we went on missions to many other worlds."

"Wow," Daniel said. "Wish I'd been there for that." He paused, considered with his thoughtful-confused face. "Well, I guess in a way I already was."

"Still," Carter said. "There must have been a lot of bad experiences, a lot of painful memories."

"Indeed there were. For example, the incident with Colonel O-Neill's son."

"Charlie," O'Neill whispered.

"But where there were unpleasant memories, there were also more pleasant ones. And where there were unpleasant memories, I simply did what the Joker has done with so many timelines: I altered them."

For a moment, silence.

Chloe stepped forward with a young familiar Vulcan. "You may remember Surnak from one of your earlier time travel missions."

"Bruce Wayne's parents," Daniel said.

"Right," Chloe said.

"How you doing, Surnak old buddy?" O'Neill said.

"Really well," Chloe said.

"Still doesn't talk much, I see," O'Neill said.

"Surnak has been given a special ability by the Q and the Ancients. He can transfer the eighty years of rest from the older you into the you-you now. Watch."

Surnak held out one hand to the tubes, another to present young SG-1. A bright white light flowed out of him.. Briefly, the team members did a kind of wobbly little dance. Once the light was gone, they stood still and straight, each one blinking in confusion. .

"You're good to go," Chloe said. Her squint-smile was so big it almost took up her entire face.

O'Neill stood over the tube containing older him.

"Listen," old O'Neill said. "I know after what you saw on Dark Vulcan, you don't want to just let us die."

"We won't," O'Neill said. "Whatever time you guys have left, you're going to be taken care of. Because you're us and we kind of like us."

"It's okay," old Carter said.

"Actually, it's not," Carter said. "If there's one thing we've learned, it's a respect for life. All life. At whatever stage."

"You can let us just die," old Daniel whispered.

"We have accomplished our objective," old Teal'c said.

"No regrets," old Beckett said in a raspy voice as he looked straight ahead.

O'Neill leaned in with a firm strong look. "Not gonna happen. We're going to find a way to take care of you."

"That has already been arranged, Colonel O-Neill," Spock said. "But it is good that you and your team hold such an attitude. It is exactly the attitude we need to successfully confront Dark Spock."

As Spock and SG-1 retreated to the ship's briefing room, Leonard found himself reunited with Sheldon, Howard, and Raj.

"Hey, guys," Leonard said. "How'd it go with the calculations for our next time-jump?"

"Good to go," Howard said. Raj gave two thumbs up.

"I get to help Spock!" Sheldon said excitedly.

They all stood in silence as they looked at aged SG-1 in their tubes.

Old O'Neill spoke in a slightly creaky voice. "Hey, guys? You're not the ones taking care of us, are you?"

A door opened, making the same whisking noise you'd hear on the "Enterprise." Two familiar figures stepped in.

Leonard made a surprised-delighted face as he spoke with a little laugh in his voice. "Jonathan and Martha Kent?"

The tall blond-haired man spoke in a laughing voice as well. "Not quite, Leonard. We're cosmic beings taking the form of Jonathan and Martha Kent."

"And I have cookies," Cosmic Martha said. "Just like your Mee-Maw makes, Sheldon."

"Yum!" Sheldon eagerly devoured one.

As all four guys munched on cookies, Cosmic Jonathan-and-Martha attended to machines above the tubes, machines similar to the ones found in Doctor McCoy's sick bay. The machines made the quiet heartbeat sound so familiar to sick bay visitors on the "Enterprise.".

"We have another surprise for you," C-Martha said as she continued to work.

"When you go home, you won't have complete memory loss," C-Jonathan said. "You'll remember some of your experiences, the good ones, as a kind of vivid daydream."

"Yay!" Sheldon exclaimed.

"That's great," aged O'Neill said. "Now could you forget about them, focus on us?"

The "Big Bang" guys retreated to another part of the room. .

"You know," Leonard said. "You could argue that in 'The City on the Edge of Forever' Captain Kirk was a good captain and a bad captain."

"He was a bad captain because he never should have fallen in love with someone in the past," Howard murmured.

"That's a classic rookie time travel mistake," Sheldon admitted. "But I don't see how that makes him a bad captain."

"Because, dude, he should have focused on his primary mission: correcting a change in the past."

"You're right, Raj. He was a bad captain that way" Leonard lifted a finger for emphasis. "But he was a good captain in that he was willing to sacrifice the woman he loved to save millions." He smiled as he held his chin up.

"He loved her? After only a few days?" Sheldon shook his head. "Human relationships will continue to baffle and elude me."

"Hi, guys," someone said.

"Chloe!" Leonard, Howard and Raj exclaimed all at once.

"Hello," Sheldon said.

The guys knew Chloe from their experiences aboard the timemobile. When Team MacGyver rescued Clark from a Belle Reve in the past, this dimension-hopping Chloe boarded with Clark. She was present when Clark, under the mental influence of the Joker, tore a hole in the timemobile. When the guys flew out that hole, they ended up meeting Captain Kirk and Spock in Smallville while they waited for Captain MacGyver to retrieve them.

Through the guys, Chloe passed on knowledge of the future to Spock. That was how this incredible rescue plan was hatched to save the day.

"Good to see you guys again," Chloe said. "I've got my own wrap-up missions to go on soon. But you're in good hands with Spock."

"I should say so," Sheldon said.

"And MacGyver is pretty good, too," Raj said.

"No argument there, Raj," Chloe said. "So listen. Once the timeline is restored, I'll help Cameron Mitchell in the past become a teacher at Smallville High. He'll provide the positive influence Captain Kirk had in the altered timeline. And all those books his wife Edie wrote? I'll write those in the new timeline."

Sheldon raised sharp eyebrows. "You mean the original timeline," he said pointedly.

"Let's not debate that, shall we, Sheldon? I start to feel like Colonel O'Neill. It gives me a headache."

Leonard smiled. "If not for Penny, I'd definitely move to Smallville for you, Chloe."

"Hey, I saw her first," Raj complained as he held a flask of Romulan ale.

"Raj, would you get that out of here?" C-Jonathan snapped.

"Maybe the old S-G-One would like some."

C-Martha took the flask from Raj and injected him with a hypospray.

"To make you sober," she explained.

Raj smiled. "I'm glad you guys didn't get blown up when the rogue Q destroyed the Time Protector Ships."

As C-Martha gave Raj another hypospray shot, Chloe gave Leonard a twitching smile.

"With all the traveling you do, Chloe, I guess it wouldn't work out." Leonard said.

Chloe smiled. "Normally, the guys I fall for are tall. But for you, I'd definitely make an exception."

"That's the spirit."

"See ya, Leonard." Chloe gave him a light kiss on the cheek then waved. "Bye, guys."

Once Chloe was gone in a flash, Howard put on a mock-pouting look.

"Oh, boo hoo," he said. "I can't be with Chloe because I have a beautiful girlfriend back home."

Leonard smiled as he bounced on his toes. "Got that right."

"Where to next, guys?" Raj asked.

"Spock and S-G-One have to pick up Clark as he confronts Lex," Leonard said. "Then we go back to the time Clark saved Edith Keeler."

"Plus the other time travel team is working on eliminating Dark Spock," Howard said. "In a non-violent time travel way."

"Cool," Raj said. "Is there a way to watch all that?"

As the Fortress time machine sailed on, the other time travel team arrived at its time and place. ...

"Jim?"

An unshaven bleary-eyed James T. Kirk, dressed in a red and black coat, looked up from his seat on the curb.

"Bones," he said. "I haven't even started drinking yet, and already there are two of you." He looked up, squinted. "And you look older. Both of you."

The McCoy with gray hair smiled as he sat down. "We're real, Jim. And we're from the future."

Wearing a gentle grin, McCoy with less gray hair spoke in a gentle quiet voice. "From the future of another world, in my case."

"I see." Kirk glanced around. "I suppose that's not so hard to believe. I am, after all, someone who traveled back in time to correct a mistake." He spread his hands. "So why not strange visitors from the future, other worlds?"

Less-gray McCoy also sat down. "We're here to help, Jim. Scotty and Uhura are here, too."

Kirk looked up with less squinting. "I see you two made it, too."

"Yes, sir," Uhura said softly. "Hello, sir."

A grinning Scotty offered a cordial nod. "Captain Kirk."

Just then, the Joker tip-toed into the scene. "Yoo-hoo, Captain Kirk," he whispered. His head shot up. "Eh?"

Scotty curled up his fist. "Get out of here, Joker. Go back where you came from."

"You're done, mister." Uhura fired her phaser, and the Joker vanished. Briefly, she and Scotty high-fived each other. Then they sat with their friends.

Kirk looked out at the street, the people, the vehicles. All the traffic going by. There was a vacant look in Jim Kirk's eyes. But there was also a hint of hope.

"Are you really here to help me, Bones?"

Gray McCoy smiled. "Of course we are, Jim. We'll stay as long as you need us to."

Less gray McCoy also smiled. "You could say we've got all the time in the world."

"We're with you, sir," Uhura said softly.

"Always and forever, Captain Kirk."

"What Scotty said." Less-gray McCoy gestured to the engineer.

"Now," gray McCoy said. "Why don't we start with you letting go of that bottle?"

Kirk glanced at the hand that gripped the bottle, and his hand uncurled. Slowly, he rose. His friends stood with him.

"What's in the crate?" Kirk asked.

"Nothing that matters anymore," gray McCoy said.

Once less-gray McCoy poured out the bottle, they all walked off together.

For the time-traveling SG-1, the scene at Cheyenne Mountain was a little more dramatic.

"Your reign is over, Luthor."

At the sound of O'Neill's voice, Clark Kent tried to make a sigh of relief but simply groaned instead. .

Clark, the white-haired wrinkled version, was on all fours, head bowed. And he was in great agonizing pain, like the sensation of a broken rib filled his entire body.

There was a reason for that. Lex Luthor, towering over Clark, held out a glowing green rock.

As he absent-mindedly moved the rock to his side, Lex glared.

"I don't know who you are. But I will not be denied this!" he roared. "The world will finally recognize my genius!"

In the background, the robed Spock looked grim and slightly shaken. Just for a moment.

Down on all fours, Clark felt relief that SG-1 was there. Even more so when the aged Mister Spock delivered a Vulcan nerve pinch to Lex. Once Lex was down, Daniel threw the kryptonite away and Carter disintegrated it with her phaser.

"Thanks," Clark groaned-whispered, still on all fours but head no longer bowed. . .

As he stood over the unconscious Lex, O'Neill lectured him. "You take over the world, you build a time machine, and you're still not happy? Give it up, baldie."

Spock also stood over Lex. The Vulcan looked grim, and worried.

O'Neill gestured to the shiny steel mountain at the center of the room.

"Is this the time machine?"

"That's it," Clark said.

"Let's take it out. Just in case." O'Neill raised his phaser.

They all fired phasers. The contraption was gone.

Daniel turned to Spock. "Mister Spock? Everything all right?"

The aged Vulcan wore his wide-eyed look. "I was thinking how Lex Luthor's words merely reflect the pride and arrogance of the human spirit, Doctor Jackson."

O'Neill gave him a look. "A little biased there, aren't you, Mister Spock?"

Spock frowned. "It was not meant as subjective judgment, Colonel O-Neill. Merely observation based on long years of experience."

"Well, you've got that over us, that's for sure." O'Neill turned to Clark, who was being helped up by Teal'c and Daniel.

"Kind of odd," Daniel grunted. "Helping a guy with super-powers."

"It happens," O'Neill said.

"Sorry, Daniel," Clark said.

As Clark stood without help, Teal'c smiled and bowed. "It is good to see you once again, Clark Kent."

"You, too, Teal'c."

"And this time it's permanent." Beckett smiled as he tilted his head. "I leaped into some guards to help the team get in."

Clark smiled. "I'm glad you did, Sam."

O'Neill approached, tapped Clark on the shoulder. "You look a little older, buddy."

"Funny. I feel young." And in fact, Clark spoke in a youthful voice. Like he was fifteen again.

"Too bad old Doc Frasier isn't here to help you out," O'Neill said.

"Though in your case Janet wouldn't know what to do really," Carter said.

"And our two Doctor McCoys are off stopping something the Joker did," O'Neill said. At Clark's confused look, the colonel raised his eyebrows. "Long story."

"I can hear about it later," Clark said.

With her blue eyes looking brighter than usual, Carter smiled up at Clark. "Ready to help us go restore the last timeline, Clark?"

"You wouldn't believe for how long, Major Sam." Clark resorted to an earlier nickname he had given Carter. Much like when he called O'Neill "Colonel Sir."

"The beam-out site's over here," Carter said, pointing.

As the team moved, O'Neill said, "Wait'll you see the nifty new time machine, Clark. Built by Mister Spock himself."

"I had some assistance," Spock said.

Again, Clark smiled, this time as he glanced at the Vulcan. "Good to see you again, Mister Spock. It's been a long time."

"It has indeed, Mister Kent. But soon it shall come to an end."

"Can't wait."

Daniel turned to O'Neill. "'Your reign is over, Luthor?' Really, Jack?"

A slight shrug from the colonel. "I had to say something to distract him until Spock could use that nerve pinch thing of his. We could use phasers on the guards but we couldn't risk Luthor activating some hidden device to destroy the world. Or whatever he might have up his sleeve."

"That was smart," Clark said. "With Lex, you never know."

O'Neill gestured to the aged Vulcan. "Can you believe it? Lex Luthor taken out by some two-hundred-year-old Vulcan."

"I am not quite two hundred years old, Colonel O-Neill."

"Still! Old Lex Luthor couldn't have seen that coming."

"Indeed," Teal'c said. "It is much like the Empire being defeated by Ewoks."

O'Neill made a face. "Wouldn't know about that, Teal'c. You know me and science fiction.." Along with the others, he took his place at the beam-in site. "Hope you're ready, Clark. This next part could get messy."

"That's a go, sir. I've been getting ready for a long time now."

"I bet you have." After a quick head count, O'Neill activated his communicator, showing some brief annoyance at the quick chirping sound. "Mac? We're ready."

"I read you, Jack," came the reply.

Daniel offered a quiet suggestion. "You could have just said 'beam me up,' Jack."

"I'm not gonna say that, Daniel."

Aboard the Fortress time machine, Daniel pointed as he explained.

"So the guys will reprogram the Terminator, Old Clark will stop young Clark, and we'll all work together to locate and take out Dark Spock."

As Daniel completed his briefing, he noted Howard and Raj spinning around in swivel chairs.

"Guys?" Daniel said. "You getting this? 'Cause this is kind of important."

"We're on it, dude. Daniel dude," Raj said. "We need to reprogram the Terminator."

"And the Terminator can help us find Dark Spock. Ready to go," Howard said with a two-fingered salute and a final spin.

"And only Clark can take out Clark," Leonard said.

"We certainly can't do that," Sheldon said. "But if I see Dark Spock, I'll take him out with my phaser." He emitted his gasping laugh.

"We can also anticipate that, like the Joker, Dark Spock will present us with unexpected situations," Spock said. "Thus, you will again require my assistance."

O'Neill wore a skeptical, and slightly concerned, look. "Look, no offense there, Mister Spock. You were great there during the whole Lex Luthor thing. But...how do I say this? You're really old, and you're likely to just get in the way this time. Why not leave this one to the time travel experts?"

As usual, Spock looked unperturbed. "I have cybernetic implants that allow me to move with ease. I shall not simply be, as you say, 'in the way.'"

"Look, we appreciate you pulling us out of the Phantom Zone. But why not take a break? Get some rest. You need it after so long."

There was a trace of a frown in Spock's face . "Colonel O-Neill, I have knowledge of the future. I'm sure you can appreciate the value of a tactical advantage."

Briefly, O'Neill wore a blank look then his eyebrows shot up.

"Welcome to the team," he said brightly.

They all sat down and contemplated where they had been, what they had done.

"You know," Clark said. "It's kind of sad about Edith Keeler."

"It is," Carter said.

With a slightly exasperated look, O'Neill waved his hand. "Could we not discuss that topic?"

"I think we need to discuss it, Jack," Daniel said.

Inwardly, O'Neill groaned. Did it say "colonel" anywhere on his uniform?

"I'm sorry about your friend, Mister Spock," Carter said.

Daniel turned to Spock. "Originally, Captain Kirk only knew her a few days before he had to let her die. You knew her for a lifetime."

"In a way, what you're doing is even more heroic than what Captain Kirk did," Beckett said.

"I will not presume to compare myself to Captain Kirk, Doctor Beckett."

"Still," Clark said. "This must kind of tough for you. Wiping out a timeline where you knew someone for so long."

"Okay, I don't like where this is going," O'Neill said.

"It is quite all right, Colonel O-Neill." Spock wore what might be called a thoughtful frown. "It is true I knew Edie for many years. For that reason, I think she would obtain great satisfaction in knowing her death brings about a future where there is freedom and hope. It is, after all, what her life stood for. After her work with the mission, she helped the local food bank alongside Martha Kent. Among other charitable endeavors. She would be most glad to know her death saves and frees people."

A brief silence followed.

"So her death won't be in vain," Carter said.

"Far from it, Major Carter."

As Clark nodded, he looked relieved and thoughtful. "That's good to know. That helps."

"We can do this," Beckett said quietly.

"Sam Beckett is indeed correct," Teal'c said. "We may now proceed in our mission without reservations or misgivings."

"We all agree then," O'Neill said.

"Yeah, Jack, we're good," Clark said.

"And our other team is off eliminating Dark Spock," Beckett said.

"We still need to be down there just in case Dark Spock gets to Spock before the other team takes him out," Daniel said.

Leonard made a face. "If the other team is off eliminating Dark Spock, shouldn't he already be gone?"

"Yeah, how does that work?" Howard asked.

Daniel crossed his arms. "I don't make the rules, guys. I just work here."

Carter smiled. "There is a theory that time is like a wave," she said.

"Yes?" Sheldon asked eagerly.

"Bup, bup, bup!" O'Neill said, holding up a finger. "Let's focus on our mission. We need to stop Dark Spock-"

"If he's there."

"Oh, he'll be there. Guy's like a cockroach." O'Neill gestured to the "Big Bang" guys. "You guys have to reprogram the Terminator-"

"Clark can help capture it," Leonard said.

"And most of all," O'Neill said sharply, "Old Clark has to stop young Clark."

"Our tricorders will alert us to the timing of key events," Daniel said. This was for the benefit of the "Big Bang" guys, who normally did not go on such missions.

The voice of Captain Angus MacGyver boomed over the ship's sound system. Both aged Spock and Old Clark held their ears.

"Guys? We're there."

"Let's move out," O'Neill said.

And so it was that minutes later...

"You guys okay?" aged Clark asked.

The city block was on fire all around him. Thanks to the flying Terminator head that had just exploded.

Despite the flames all around, Kirk, Spock, McCoy and the very-much-alive Edith Keeler stared at the strange visitors.

Young-Clark-from-the-past had rescued Edith Keeler once again and dropped her off with some friends. He had long since gone on his super-speeding way.

"Everyone okay?" Old Clark asked again.

"We're okay, Clark," Daniel said.

"Good as gold," O'Neill said.

"Thanks for super-speeding us out of the blast zone," Carter said.

"We are indeed able to battle on because of you, Clark Kent," Teal'c said with a slight bow.

"Thank Spock for the warning," Clark (old version) said.

"He also warned us that Terminator can multiply," Beckett said as he surveyed the scene.

"The guys seem to have a handle on that," Clark (again, old) said.

Beyond the flames, the "Big Bang" guys tinkered with a headless Terminator while Spock calmly issued instructions. Nearby, two Terminators held a struggling Dark Spock.

"They've already reprogrammed two of them," Beckett observed. "And on this leap, we stopped Dark Spock from getting to younger Spock in the past."

"There's a sentence I thought I'd never hear," O'Neill said.

As he crossed his arms, Daniel wore his squinty-eyed look. "Still, this is a mess."

"And who knows where Dark Spock will show up next time?" Carter asked.

Oddly, Colonel O'Neill seemed not only calm but almost serene. "It's a little more complicated than we'd like. But we'll be all right."

"It's still a mess right now, Jack."

With just the hint of a grin, O'Neill held up the Restart Device. "That's the nice thing about time travel, Daniel. If at first you don't succeed..."

He pressed "restart."

"How you guys doing there?" O'Neill shouted as he fired his phaser.

Leonard shouted back over phaser fire. "We're doing great, Colonel O-Neill! Last one!"

"Finally," Howard muttered as he closed the control panel on the Terminator.

Swiftly, the Terminator rose and joined SG-1 and three other Terminators in firing on Klingons and Jaffa.

Earlier, Spock had warned the team about another complication. Now, Raj and Sheldon worked on a solution to that problem.

"We're almost done here!" Raj shouted in a voice that was almost giddy. While Sheldon used a laptop, Raj swiftly assembled parts from an interdimensional storage space.

"Yay!" Sheldon shouted.

Raj held up the device and flipped a switch. In the east and the west, portals closed. Wherever Dark Spock was hiding, he had arranged portals that poured out Jaffa and Klingons. Once those portals sealed up, SG-1 took out the last of the enemy with their phasers right alongside their Terminator brother-in-arms. The Terminators used phasers rigged up by MacGyver.

Spock stood holding his phaser up. "Thank you for your assistance, Sheldon. All of you."

"Anything for you, Spock," Sheldon said as his friends murmured their thanks.

"I would ask that you and your associates assist me as we search for Dark Spock."

"Of course!" "Sure thing!" "Yeah!" The guys were very enthusiastic and excited.

Daniel thought how good it was that the guys were so excited about what they were doing they didn't even have time to be afraid.

"We're with you, too, Spock," O'Neill said as the entire team moved through the night crowds.

There was a slight gasp from the older Vulcan. It was understandable. Captain Kirk and Edith, the younger ones from the past, walked down the street together. Quietly and slowly, the team trailed them.

Raj leaned in toward Leonard. "What if Captain Kirk remembers the weird stuff that happened here?"

Smiling, Leonard whispered back. "They won't. The Restart Device has a 'wipe' function. All Colonel O-Neill has to do is push that button and memories get wiped out, physical evidence is erased. "

"It's kind of a rewind," Howard said.

"Not quite accurate," Sheldon said. "But yes, essentially everything plays out just like it did before in the original timeline."

"Cool," Raj said with an approving nod and a smile.

Carter consulted her tricorder. "No sign of Dark Spock."

Spock wore a narrow-eyed concerned look. "Unfortunately, Major Carter, he has ways of evading a tricorder reading. But I am able to sense the presence of another Vulcan, even one so..."

"Dark?" Howard offered. "Twisted? Demented? Utterly depraved?"

"Quite so, Mister Wolowitz. In some ways, we deal with a threat even greater than the Joker." The Vulcan's eyebrows shot up. "There!" he shouted as he pointed to an alley.

"Let me help." Beckett vanished and next thing you know a bum stepped out of the alley, moving his fists like a boxer. "Come on and fight me, you!"

Dark Spock stepped out of the alley. Ignoring Bum-Beckett, the dark-eyed Vulcan followed Kirk and Edith. Clark and the "Big Bang" guys shouted, "Dark Spock! Over here!" When Dark Spock turned, Old Spock applied the Vulcan nerve pinch.

Old Spock held the slumped Dark Spock in his arms.

"We're almost done here," O'Neill said.

"Let's hope," Daniel said.

At first, Dark Spock, in the grip of the aged Mister Spock, stood with his head bowed. O'Neill thought that was a bad sign. No way would the Vulcan be so easily cowed.

Sure enough, the Vulcan looked up, black eyes glowing. The voice was deep and rumbling but still with a trace of Spock.

"You forget, S-G-One. Despite my logical Vulcan nature, I can, like the Joker, do the unexpected."

His hands shot out, blasting the team members with Dark Power.

In each mind, Darkness was unleashed.

Clark ruled over the Phantom Zone with a gladiator army.

As global dictator, Daniel ordered a nuclear strike on Russia.

Carter was a Replicator who looked human, a ruthless being who tortured Daniel to tap into his knowledge from the Ancients.

Teal'c acted as enforcer for Dark Spock, the equivalent of First Prime to Apophis. .

Beckett was an evil leaper, bringing negative changes into the lives of others. In his mind, he cackled loudly as he sent Jimmy, a young man with Downs Syndrome, into an institution.

The "Big Bang" guys were aimless criminals, using their knowledge of science to annoy and hurt others.

For Spock, his darkness was...

,,,the world had denied his genius.

Yes, much like Lex Luthor, he had toiled without recognition.

He had spent years in Smallville doing work that was beneath him as he lived in a primitive time period among people who were clearly his inferiors.

He remembered being stared at by people in Smallville. Women, children, arrogant men. Knowledge of the future meant that he, like Nelson Kent, often mumbled things out loud.

All those years he toiled,.repressed and oppressed, living benath his potential.

Now he could be something more, something greater.

All he had to do was reach out, grab the neck of Edith Keeler...

No!

He thought of the decent, helpful people from Smallville. Jim. Edie. Cassie. McCoy. Eve Garfield. Hiram and Jessica Kent. Perry White. Jonathan and Martha. Even Principal Kwan.

There were those he saw in his visions of the future. Lana. Chloe. Pete. And especially, Clark.

Dropping his hands to his side, Spock quickly moved away from the young Edie.

As he looked around, he saw the other team members shaking their heads, looking confused and bewildered. But there was no evil in their eyes that he could see.

They were fighting it.

All except Colonel O'Neill.

He just stood there looking calm and confident.

"Nice try, Dark Spock," he said in a smooth even voice. "But with all the stuff we've been through with the Joker, that kind of thing doesn't work so great."

With a casual motion of his hand, O'Neill fired his phaser, putting Dark Spock into a temporary time-freeze.

"Everyone, form a guard around him," he ordered. "If he moves, time-freeze him again. As often as it takes."

O'Neill shook his head. Some kind of mental manipulation by Dark Spock must have prevented them all from using the time-freeze earlier.

"Spock, you all right?" Daniel asked.

"Yes, Spock, are you okay?" Sheldon asked quietly.

"I believe so, Sheldon. Doctor Jackson."

As Spock stood with a wrinkled hand to his bowed head, O'Neill tried to keep irritation out of his voice. "Spock, you know the future. Why didn't you warn us about this mental attack?"

As Daniel and Sheldon assisted him, Spock stood up straight. "You yourself said it, Colonel O-Neill. Your trials have strengthened you."

"That may be but...ah, never mind." O'Neill glanced at Dark Spock, still frozen with a slightly stunned look. "I just hope he's gone before the time-freeze wears off."

As if on cue, Dark Spock vanished.

"It appears Team McCoy was successful," Teal'c said.

Old Clark wrinkled up his eyebrows. "You call them Team McCoy?"

"We had to call them something, Clark," Beckett said.

"'The other team' didn't have much of a ring to it," Daniel said.

Carter smiled. "I didn't like the name very much either, Clark."

"I wanted to call them 'The Real McCoys,'" O'Neill said with eyebrows up.

Carter consulted her tricorder. "The area's clear of Jaffa and Klingons, sir. No sign of any other anomalies."

"Everyone stay alert just in case," O'Neill said.

Daniel pointed. "The Guardian's located the younger Clark. Right there."

O'Neill nodded to his tall old friend. "Get ready, Clark."

"I'll let you know the precise time, Clark," Carter said, still holding her tricorder.

At that precise time, young Clark rose and began super-speeding. Only to violently collide with...himself.

As he lay on the ground, young Clark was vaguely aware of others in the area. People he'd seen in his flashbacks.

Looking very puzzled and confused, young Clark slowly rose and focused on the very old large face in front of him.

"Trust me," Old Clark said. "You don't want to do that."

Young Clark vanished, and Old Clark morphed back into his normal young self.

Focused as they were on the two Clarks (and then one Clark), most of the team members had their backs turned as Edith Keeler crossed the street. (Spock was deliberate in doing so; he even closed his eyes as he faced the other way.) It's probably safe to say each individual felt sick at the sound of the truck braking and people crying out.

After the sickening noises, each team member turned toward the dark figures near the truck. The small crowd kept them from seeing the body.

In the now quiet night, they heard familiar identifiable voices.

"Jim, do you know what you've done?" McCoy demanded.

The stoic voice of Spock followed.

"He knows, doctor. He knows."

Old Spock whispered along with his younger self.

Slowly and in silence, the team members walked toward the accident site. As they did, young-Spock-from-the-past stepped into the headlights. The look on his face suggested he was contemplating the life Edith Keeler could have had somewhere.

"Guys?" Daniel said. "Maybe we could have a moment of silence now."

From where they stood, the team members bowed their heads.

It was a moment of silence not only for Edith Keeler but also for Bruce Wayne's parents.

It was a moment of silence for criminals like Joe Chill and meteor freaks like Greg Arkin and Tina Greer (among others), a moment for all those like them with the hope they would all get better.

It was a silent moment to honor all those who died in service to Stargate Command and Starfleet.

It was a moment to honor allies of Clark who, like Edith Keeler, died to bring about a better future. U.S. Marine Whitney Fordman. Jonathan Kent. Raya. Lionel Luthor. Tess Mercer.

The silence was broken when Captain Kirk spoke in a choked whisper.

"Let's get out of here."

"The captain's right," O'Neill said quietly. "Let's go home, guys."

Raising the Restart Device, O'Neill pressed "wipe."
