A/N: I kinda forgot to mention any spoilers, um well pretty much general stuff to the end of season 8.

Chapter Three.

Doctor Frasier was an exceedingly thorough individual. After subjecting SG-1 to every test known to man, except for Sam who was limited to tests that were safe for the foetus, they had finally been allowed to leave the infirmary for the briefing with the General.

Escorted by the two SF's, the team climbed the spiral staircase and entered the briefing room just as Jack left his office and seated himself at the head of the table, SG-1 followed suit with Sam sitting to his right – at least that was normal Jack thought – Daniel next to her and Teal'c taking the seat at his left.

"OK campers, we're here in the briefing room," Jack began sarcastically, with a wave of his hand to illustrate his point; yep he was still a little pissed. "Frasier just called, you are…ah you know, not some freaky aliens who look like you. Apparently you aren't suffering any brain damage either, though I'm thinking of calling in a second opinion on that one." Sam winced at his tone. "So anyone care to share with me just what the hell is going on with you." His gaze moved from Teal'c to Daniel, before settling on Sam, waiting.

"Ok. Well sir, it seems that we," and here she moved her hand to indicate Daniel, Teal'c and herself, "are not from this particular reality." She paused, wait for it…

"What?" Jack asked, his face screwing up in confusion.

"I'm not sure yet how it happened exactly sir, but everything we've seen and heard since coming back through the 'gate definitely indicates that this is some sort of parallel world to ours, very similar, but with marked differences."

Jack slowly leant over and allowed his head to thump onto the briefing room table and then proceeded to shake it side to side. "You sure you didn't just hit you're heads or somethin'?" His voice was fairly muffled, but they heard.

"We did not." Teal'c replied.

"Ok, there's just some things I don't understand," Daniel began.

Jack's head shot back up, "Just some things?" He said incredulously. Daniel shot him a look, well at least that was the same Jack thought.

"When I went through the Quantum mirror originally, I went there as me, same clothes and everything. But, well Sam you are definitely not the same and my hair is definitely longer than it was this morning." Daniel continued.

"Yes, I know I thought about that. Umm, apart from the rather obvious difference," Sam glanced down to her distended belly, "I was also wearing different clothing, my vest and P90 were gone."

"You," Jack spoke up, looking at Sam again. Though he tried to mask it, she saw the apprehension in his eyes. "Sam…can't wear a combat vest anymore, turns out they don't make them in the maternity lines. And Doc's orders were no heavy lifting, which she said included big guns, go figure." He smiled at her, she looked just like his Sam…his smile vanished as his eyes flicked over all of them, then he abruptly rose and practically flew down the stairs into the control room.

"Walter dial up P3X 292 now!" Jack ordered as SG-1 caught up with him.

"Yes General." Sgt. Harriman said as he started the dialling sequence. Whilst Jack was retired and therefore not officially a General anymore, retired senior officers were still often addressed by their former rank. It was a sign of respect that everyone on base still called him General. "Chevron one encoded sir."

It seemed like forever to Jack that the wormhole finally established. He keyed the comm. himself and spoke into the small microphone.

"Stargate Command to SG-7, come-in!" He said roughly.

"Yes sir, go ahead." Came the response.

"Are SG-1 still on planet with you?" Jack asked. There was a long pause on the other end. Walter looked up at the SGC's commander in surprise and then over his shoulder to SG-1.

"SG-1 left through the 'gate around one hundred and sixty minutes ago sir."

Jack felt a fist form tight inside his chest, "Are you certain Major?" He said gruffly, his face like chiselled stone as he stood stock still.

"Yes sir, Lieutenant Andrews was with them at the 'gate and saw them go through sir, she also says the coordinates were definitely correct for earth sir."

"Thankyou Major, O'Neill out. Shut it down Walter." Slowly Jack turned to the SG-1 standing behind him in the control room, "Well I think it safe to assume that my SG-1 never made it back here, so where the hell is my SG-1?" As he stormed back toward the briefing room the others followed, exchanging concerned glances.

As Jack took the first step of the staircase he stopped suddenly and turned around, locking eyes with Sam. "Ah crap!" he exclaimed. Moving to Sam's side, he brushed away a lock of her hair with a gentle hand. "I'm sorry Sam, I'm such an ass. C'mon."

Jack felt like a total prick. She may not be his Sam, but she was still Sam and she was still heavily pregnant, he'd forgotten how hard it was getting for her to go up and down this steep staircase. He put his left arm around her shoulders and used his right hand to hold hers as he helped her up the stairs. She was looking at him with bright, wide eyes and he noticed the slight blush that spread over her lovely face. He guessed that she wasn't used to having him hold her and that coupled with the fact that she called him 'sir' all the damn time, told him that things were different between her and her Jack in her world.

When they managed to get back to the briefing room, Sam was breathing heavily. Jack pulled her chair out for her and she gratefully sank into it as everyone else also took their seats again.

"Sir, I've been thinking," Sam said. Jack smiled, yep just like his Sam. "You're team went through the 'gate for home, but never got here, instead we arrived. I think that somehow we got switched, you're SG-1 is most likely in our reality." She concluded waving her hand at Daniel and Teal'c.

"Ok so say I believe this…" Jack was interrupted by Daniel.

"It's not that hard to believe is it Jack, I mean I know in our reality we've had some experience with different realities?"

Jack glared at him, "so what now?"

"Well sir, Daniel, actually this is very different from the other experiences we've had. There was no quantum mirror involved. Somehow the 'gate must be responsible, but I have no idea how that could be. Not only this but we've actually, well, swapped bodies. Sir, I recommend limiting non-essential 'gate travel until we figure out how this happened."

"Right and how the hell you're going to fix it Sam." Jack felt better knowing that his Sam and the rest of his friends were safe in her reality, but well the whole thing was way too weird. He was about to have a baby with someone who looked like his wife but wasn't really and his wife was somewhere with the him who has no idea where that sweet mole is. "Do what you have to do, but Sam take it easy ok." He reached over to place his hand over hers, but she pulled her hands away. He felt like someone had kicked him in the guts, but shook it off, reminding himself that this wasn't his Sam. "Well go to it." He said, raising and returning to his office.

Sam noticed him reach for her hands, she couldn't help it, she didn't want him to touch her, she wasn't his wife and he wasn't her Jack, ahh General, not that her General was hers. She took a deep, cleansing breath and stood. SG-1 made their way to Sam's lab, to try and figure out how this could have happened.
