Author's Note: Thanks once again for all the wonderful reviews! :D It's amazing how encouraging it is to know people are enjoying themselves reading something I've written. Especially since I know most crossovers tend to lean towards humour and since humour isn't my best front I tend to lean towards the serious. So the very fact that I've got peeps still eager to read each chapter, well, it makes me grin like a dopey idiot! :D

Author's Note2: This will be my last author's note on Jack and Mac…at least for a while. I realized in the last couple of chapters I've been replying to guesses about the who, what, and why of the whole thing. And I've got to warn you it'll be several chapters before the full truth about their relationship comes out. So from here on out I'm just going to let the story drop all the hints. The only thing I can really do as an author is tell you that a lot of thought went into this story and I tried really hard to make sure it was something scientifically feasible…at least in theory. ;)

Author's Note3: To Glaivester: Since I've never actually seen "Legend" I'm not sure I'll put a reference in, but I'll keep it in mind while I'm writing. I'll tell ya though, finding out about "Legend" does at least explain a funny fic I once read. :D

Author's Note4: I got a Dancing Hamster!!! He's decked out in combat gear; carry's a gun I like to pretend is a P90; and dances to the army theme. It'd have been cooler if it was the air force theme or better yet the stargate theme…maybe if I write them a request? *g* His tag has him named as Sgt. Scruffy, but to me he's Jack. :D

Author's Note5: I got all my 'brakes' replaced, ;) Thanks Suz! :D

Sam watched as the Colonel paused at an intersection, first turning one way then changing his mind and leading them down the other. She guessed that the engine room had to be located at the back of the ship from their existent knowledge of goa'uld ships, but even Teal'c had admitted this one was of no design he was familiar with. They were guessing, plain and simple.

Turning to look at the man she'd thought was her superior all morning, Sam felt a mix of feelings. In the academy she'd heard the legends of MacGyver, but to actually get to meet him, let alone to find out he was related to her CO. Not that that made much sense, she was sure his file had him listed as an only child, but the resemblance was too identical to deny.

"What?"

Sam suddenly realized she'd been staring and blushed. Daniel was suspended half off the ground with his arms around Teal'c and MacGyver, but one look at Sam and the anthropologist nearly lost his step. Sam thought she even saw a flicker of a smile on Teal'c's face, but MacGyver on the other hand seemed only more confused. "What?"

Sam stepped closer, and with a small smile questioned, "You really are MacGyver, right?"

The man looked down somewhat abashed, but answered lightly, "Last time I checked."

Unable to stop the grin from spreading across her face Sam finally had to ask, "Did you really smuggle yourself out of Berlin in a coffin, fight off an army of ants, and defuse a missile with only a paper clip?"

MacGyver gave her a pained expression replying weakly, "Not in that order."

Daniel and Teal'c were both looking at the man with raised eyebrows but then the Colonel came back and growled out, "He's blown up my house, too. Isn't he all just so fantastic!"

Carter suddenly realized there was a lot more going on unsaid between the Colonel and his twin brother which brought her back to the earlier conversation, but before she could say anything MacGyver, looking hurt, complained, "You know I had no choice Jack."

"Isn't it you who keeps saying 'you always have a choice?'" The Colonel retorted.

MacGyver didn't respond, but Teal'c was quick to question, "What purpose would you have in the use of an explosive device in O'Neill's residence?"

Once again Sam noticed both the Colonel and MacGyver looking somewhat uncomfortable, like they'd been caught in a slip. Certainly, it couldn't have happened anytime soon or they'd have known about it. Then Jack waved a hand at the jaffa, saying amiably, "Never mind T. It's no big. I'm just anxious to get out of here."

Amazingly, at the next turn they came across a door labeled power in Goa'uld. The door didn't have the usual handle, and stepping up to examine the small control console Sam realized it was a combination pad. Twelve buttons with hieroglyphs like the keypads on the Tel'tac's but never before had she seen them used as a locking mechanism. "Sir, I'm not sure-" she started, surprised when the Colonel just reached over and pressed a few of the bottoms seemingly at random. Smirking at his usual impatient tendencies to fiddle with things, Sam was about to tell him they'd have to reroute power to a different control consul to go around the lock when suddenly the door clicked and on old tracks slowly slid open.

"How..?"

The Colonel grinned at her. "It only works once, so come on. And T see if you can keep this door from closing, would you?"

Another surge of questions bubbled up inside her, but the Colonel was already taking Teal'c's spot in holding Daniel up and together with MacGyver they moved inside. Obediently, Teal'c took up position inside the doorway where sensors would keep it from closing, and Sam, looking up at the jaffa's unreadable face questioned, "Is it just me or has the Colonel been acting kind of strange since his brother showed up?"

"Indeed."

With a sigh, Sam realized there were too many questions right now and not enough time to ask them. Later, she promised herself, she would find out what was really going on. She'd never even asked about the alien device Daniel and the others had been looking at before. And right now, with Daniel looking half dead on his feet and the Colonel and his twin acting so oddly, she knew now wasn't the time. It'd all come out in the briefing when they got back anyway.

Walking to room revealed exactly what they had been looking for. There was even a rhythm of power going through the center power generator. Daniel had been parked just inside the door while the Colonel and MacGyver examined the controls.

Approaching them, Sam felt her stomach flutter again in anticipation. She knew it was silly, but she'd heard so many things about MacGyver's skills, and here she might actually get to see them. Then again, she could macgyver better than anyone in her class, and felt obliged to suggest, "Sir, with the generator running we could cause an overcharge in the system that would start a chain reaction that I think would take out the whole ship."

O'Neill just gave her a pained look and asked plaintively, "Can't we just use the C4?"

Sam blinked. "That would work, too."

Beside her MacGyver softly chuckled, then asked, "This is a ship right? Is there anyway way for us to fly it?"

"Goa'uld ships use a electromagnetic field to suspend themselves above the ground, and the naquadah reactors create a-"

The Colonel cut her off saying, "I think what he's asking is, is there a way to turn the thrusters on?"

Frowning, Sam replied, "Goa'uld ships don't actually use thrusters, sir, but yes, I suppose, but they're not designed to operate in any kind of atmosphere other than space." She couldn't for the life of her understand what turning on the engines would do, it couldn't get them out of the ground, and didn't the Colonel intend to blow the ship anyway?

Yet MacGyver had a glint in his eye and insistently asked her, "But we can turn on this electromagnet field, right?"

"Yes. But it can't get us out of the ground, all it will do is-"

"Cause an earthquake. Which is exactly what we want." MacGyver was full out grinning now which only confused Sam even more till he reminded her, "We're supposed to be demons down here. We might as well give them what they expect."

Now Carter understood and she immediately went to the console even as the Colonel began setting the C4 explosives. "I'll have to seal off controls to prevent the goa'uld from turning the suspension field off," Sam told them working quickly. "Once it's set there won't be a way to turn it off."

"Hopefully we won't need to," MacGyver remarked with a smile.

O'Neill came back from around the generator saying half under his breath, "Hope will have nothing to do with it."

There was the sudden sound of gunfire from the door and Teal'c called back to them, "More goa'uld have been awaken."

"Stay there Teal'c!" Jack called back. "Carter? We gotta go."

"Almost done, sir." She fit the last crystal into place and felt the ship give out a small tremor. It wasn't bad now, but that would change as the pressure on the ground around them increased.

"Great, lets go," Jack stated almost pulling her by the elbow as they rushed back for the door.

With the commotion of the gunfire Daniel was trying to get back to his feet and asked as they approached, "Are we really blowing the ship up?"

"Blowing the ship, making our own earthquake, hell if everything goes well we might even take out this entire planet," Jack exaggerated sarcastically, but Sam had an suspicion he was only half joking.

She joined Teal'c by the door to see four of the kangaroo dog like creatures at the other end of the hallway along with one slug like oversized rabbit. Certainly not creatures that ever existed on Earth, that was for sure. She added her own shots to Teal'c's and while the creatures stayed out in the corridor, the bullets didn't seem to be having any kind of lasting effect.

"Sir, bullets aren't strong enough."

"Mac, give her a grenade," The Colonel ordered as they pulled Daniel up between them. MacGyver tossed one over and Sam wasted no time in pulling the pin and rolling it down the hall, but it didn't go off.

"Sir?"

"Oh for crying out loud! I am not becoming a snake head today!" The Colonel stated adamantly. He ducked out from under Daniel's arm and grabbing the zat from MacGyver's belt pushed past Carter and Teal'c and ran out into the hall.

"Sir!" Sam called out alarmed to see her CO suddenly so reckless, but it was too late. He was already charging headlong down the corridor firing the whole time. For a brief moment she saw all the creatures lunging at him, closing off the way back, but in the next moment the light of energy filled the hall till at last every one of them was dead and disintegrated.

"He never said it did that," an amused voice commented from behind her. Sam looked briefly at MacGyver but with a pang of worry looked back to see the Colonel slowly walking back to them thankfully uninjured.

"Come on slowpokes, let's go!"

*****

Daniel tried to keep his eyes open, but it was getting harder and harder with every hopping step. Either he'd been given more morphine, or his body was starting to shut down on him. He didn't remember getting another shot of meds, so he had to assume it was the latter. Not something he was supposed to do without Janet's expressed permission.

"Jack."

"What is it?"

It took Daniel a moment to realize Jack wasn't the person helping him along. That just made the exhaustion that much worse. "Leave me."

"Daniel, we are not doing this."

But Daniel knew he was holding them back. His whole body was shaking he was that exhausted. Then the other Jack next to him said, "I think his fever's back. How long before the C4 goes?"

"Long enough."

Beside them Teal'c rumbled out, "This ship might not withstand this continued amount of shaking for much longer."

Daniel tried to look up at him confused. The ship was shaking? He thought it was just him. Then the other Jack replied, "He's got a point. Are we almost there?"

Sam was the one in the lead as the group ran down the hallways, pausing at each intersection only long enough to check for more goa'ulds. "It's just up ahead. I think."

"You think?" Jack demanded.

"It was a little dark, sir," Carter dryly replied, but the next junction led to the circular room that housed one set of transport rings and two large logs. It was a much smaller room than the one he and the two Jacks came down from. Gratefully it also meant if the switch for the rings was operational all they needed was to hit it and there'd be enough time to get inside them before they went up. Which was good, because he only had the one shoelace left.

As soon as they entered the little room Teal'c went to pull the logs from the room while one of the Jacks helped Daniel to sit down against the wall. Breathing out an extended sigh of relief, Daniel let his eyes drift close as the rest of him tried to find a more comfortable position.

To the anthropologist only a second passed, but when he opened his eyes again the logs were gone, Teal'c was standing guard at the entrance, Jack and Sam had a panel off the wall, and the other Jack was busy emptying their grenades of their explosive powder in a circle on the ground.

Daniel frowned. "Jack, what are you doing?"

The Jack with the grenades looked up and over at him, his face creasing deeply with worry. "Just making some fireworks. How you holding up?"

"It is the ship shaking, right?" Daniel asked not completely sure, but the vibrations that reverberated through his body felt more external now that he was sitting.

"Yes, Daniel, the ship is shaking," Jack replied and then turned to the other Jack. "Mac, you ready to go?"

"Ya," The other Jack answer. He and Sam were bent over the exposed wall conversing quietly, but they stepped away from it now joining Jack in the center of the room. "This one wasn't tampered with like the other one, works just fine."

"Great. Then let's do this."

Sam walked over to Daniel, crouching down next to him with an encouraging smile as they watched both Jacks. One pulled the pin from the last remaining grenade and placed it in the middle of the circle of powder while the other hit the switch in the wall to activate the rings. The grenades went upstairs while a thin circle of sand from the ground above appeared in front of them.

Silently everyone waited. Then Daniel saw Jack open his mouth to say something right as the sound of a large explosion echoed back down, showering them all with dirt and even breaking a corner of the room's ceiling.

After that the shaking of the ship became drastically worse making Daniel a little more nervous as the waving of his stomach timed itself to the waving of the ground. "Ah, Jack?"

At the same time Teal'c began firing into the hallway. "O'Neill, there are several more goa'uld approaching."

"All right kids, time to go!" Jack called out.

Daniel groaned as Sam helped him back to his feet which was made harder by the unsteady ground. Daniel wasn't sure what was better, having to run again or simply staying here till the ship blew.

Teal'c closed the door to the room and zated the switch. It wouldn't keep the door closed forever, but hopefully long enough.

"Sir, what if the explosion didn't scare off the natives?" Sam asked as they all crowded into the center of the room.

"We have a fifty fifty chance it did Carter. Think positive."

But the other Jack seemed to become dismayed at those words and as they disappeared in the blue of the transporter Daniel distinctly heard him groan out, "Aww man! You jinxed it!"

No sooner had they surfaced than they were being fired upon. Daniel didn't have a clear vision of everything that was happening, but they somehow made it to an overturned wagon without injury. Well, without any new injury. The jarring on his leg made Daniel cry out at one point and while his friends fired back Daniel concentrated on regaining proper control over his breathing. His leg was long past the throbbing stages and well advanced into the sharp numbing sensations that spiked with even the slightest movement.

Gripping it as if he could squeeze out the pain, Daniel finally felt he had a bit more control and took his first good look around. The city was for the most part made of wood. Several of the buildings looked somewhat singed at the edges, probably from the grenade powder going off, but as far as he could tell the city was devoid of anyone but the people firing upon them.

It was the human's posing as jaffa that Sam had told them about. They were using staff weapons and yelling out something about demons, or at least that's Daniel thought they were talking about. Yet they were still maintaining their distance, probably out of fear. One of them in particular, and older man, was yelling at the rest as if encouraging them to get closer, but even at that distance a couple of the shots came close and all it would really take was for one to be dead on.

Then Daniel noticed as Jack slunk back away from the group and skimming around the edge of the field headed for the backside of one of the buildings. "Wonder where he's going," Daniel murmured confused.

The rest looked at him, and then followed Daniel's line of sight. The other Jack let out a large groan. "Oh for crying out loud, why does that man have to do everything the hard way?!"

"Sir?" Carter asked, but they could soon see what Jack was up to as he scaled the building and crept across the roof till he was just above the native in charge. In the next moment Jack had jumped from the roof landing on the old man and causing a complete uproar among the rest of the jaffa, or were they humans?

"Come on," Jack growled out as he and Teal'c dashed forward to assist the other Jack. Sam and Daniel followed a few seconds later, and by the time he'd managed to hobble his way over the situation had resulted in a stalemate with the natives unsure what to do while their leader was held hostage. Yet the old man was screaming orders at them that didn't take an anthropologist to interpret.

Scrunching his face as he listened Daniel thought he could make out most of what they were saying, but the dialect was really throwing him off. Then Jack was ordering him, "Daniel, tell them this place is going to explode any minute now."

Daniel tried, but he was sure it was coming out right. Forcing his fuzzy mind to work he changed his tactics and waving a hand in the air screamed at them that the land was cursed, to get away, and that more demons would come if they didn't.

The natives quieted, but then their leader squirming in Jack's arms yelled to Daniel something about demons being locked in the earth. Daniel replied simply that the earth was angry. Why else would it shake so? Stay and they would be swallowed up.

That seemed to do the trick and the rest of the natives backed up a pace in fear. The old man stopped yelling, looking around him and down at the ground as if it would open up right then. Which it might, Daniel realized. Then Jack let the man go and he took a few steps away as if still unsure whether to take flight or fight. The other Jack fired his gun at their feet and the natives finally took off in a quick retreat.

"Good work," Jack told Daniel with a pat on his shoulder. Watching the natives flee Jack stated, "We better get going ourselves before we get caught in the blast."
