A/N: This story has been floating around for a while. just finally got around to posting it.

Reviews welcome, especially any criticism.

Unfortunately I do not own or have any affiliation towards the Stargate franchise.

Have taken some snip-its from the episode '200' please don't punish me for it. it was essential to this story.

Enjoy ;)

"Incoming wormhole. General Hammond to the control room." Walter's voice reverberated through the speakers.

Within seconds General Hammond came waltzing down the stairs from his office.

"Status report." General Hammond barked.

"It's SG-1's IDC Sir, they're early." Sergeant Harriman confirmed.

"Open the iris."

Hammond waited a while before, heading down the few steps to the Gate room. He waited because more often than not, when SG-1 came back early it was often because a mission went wrong, planet was empty, or trouble found them. He learned a while ago now, it was safer to wait. As did many other personal.

General Hammond appeared though the already opened reinforced blast doors. Before him fully dressed in combat ready BDU's were his flagship team, Daniel Jackson, Major Samantha Carter and Teal'c. However, SG1's leader Colonel Jack O'Neill was nowhere to be seen.

Looking puzzled General Hammond was about to ask where he was? And what had happened?

Before he had a chance to answer he heard his voice.

"I'm over here Sir." Colonel O'Neill's voice came through loud and clear, but couldn't be seen.

Hammond was confused he, though he was imagining things, he looked over in his best 'tell me now' face pointed directly at Major Carter.

"He's Invisible Sir, We hit some complications on the recon..." Carter concluded, almost embarrassed to utter the words.

"Invisible?" General Hammond though he really was going crazy.

"Yes Sir I'm over here, im waving at you Sir." Jack found this situation highly amusing.

"What, how did that happen?" Hammond commanded.

"The Goa'uld showed up unannounced, We decided to do some recon on the Tel'tek there was a power surge and well, next thing we knew we were all prodding around trying to search for an invisible Jack." Daniel said.

"Go to Dr Frasier she'll be waiting for you. straight for a debrief immediately after." George ordered.


In the infirmary Jack was having quite the fun time. Dr Janet Frasier was already losing her patience, trying to get the routine checks done were proving rather difficult without having Jack's full cooperation. He disappeared numerous times during the X-ray, resulting in him having to be tied down. When it came to his Shots he refused to allow the nurse to give him his shot, instead requesting that she played pin the needle on the donkey. Which on resulted in a rather angry Colonel and a nurse apologising endlessly. In the end the nurse left the room almost in tears, that Janet newly dubbed 'Napoleon Power Monger' pulled rank over Colonel O'Neill threatening him with court martial, if he continued to behave this way.


"How did this happen. Major?" General Hammond asked.

"Well Sir I'm not entirely sure! One minute we were standing in the engine room, setting charges the next a shortage erupted on the ships clocking crystals, causing a small electrical charge. Colonel O'Neill was standing the closet, when we came from hiding we heard Colonel O'Neill groaning but we couldn't see him Sir." Carter replied.

"Why was the Goa'uld there in the first place? Didn't the villagers state that they hadn't seen the Goa'uld in nearly a decade?" Hammond looked more confused by the second.

"Yes Sir, That's what they said, they were confused as we were. Ancient texts dictate that they last visited P05-964, Earths equivalent 60 years. We know from their limited historical records the planet used to be rich in Naquadah, but since not filling the quotas the Goa'uld Nirrti abandoned the planet. It is possible they sent a scout to see what's going on there." Daniel said sincerely, looking towards Teal'c to confirm his thesis.

"It is very possible, Naquadah mines have been known to replenish, although, it is rare." Teal'c confirmed in his deepest sincere voice.

"Well, how can we fix this..."

"Er excuses me Sir. I'm right here and I don't need fixing." O'Neill almost shouted.

"Colonel you cannot remain 'Invisible'" he turned to Carter looked at her squarely in the eyes. "Fix it, Dismissed."

General Hammond looked at everyone, mainly where he assumed Jack had been sitting, in the empty chair before him. Standing up he put the palm of his hands on the table, glaring at O'Neill, before retreating to his office.

Sam stood up as the General left; she turned to the empty chair, hopefully looking at Jack.

"Sir, I'm going to need you to come to my lab, I'd like to run a few tests." Carter asked.

"I'm not a lab rat Carter."

"Indeed you are not O'Neill, But perhaps Major Carter can determine what caused you to become. Invisible" Teal'c harrowed.

"She's right Jack. If anyone can fix this, it will be Sam." Daniel looked at Sam giving her an encouraging look.

"Sir, we should get started right away."

"Oh for cryin' out loud. Fine lead the way Carter."


Within Sam's lab she was scanning Jack with a particle reader, looking over to the computer typing up, recording the data.

"You know Carter I'm invisible no one would know... If we happened too..." Jack trailed off.

"Sir." A flush started to creep to her cheeks, causing them to be a rosy pink.

"Well, they can't exactly, get caught if there is no evidence."

"Sir, we can't risk it."

"Spoil sport."

"Sorry sir, I'd rather not face the consequences just yet."

"Well I could at least do this." Jack walked around and started massaging Sam's soldiers.

"Erm, Sir I'm detecting slight radiation levels from you, it would be wise if..." She trailed off feeling that He was no longer massaging he, and couldn't quite remember when he stopped she was too focused typing commands into her computer. "Er Sir... Dammit."

She walked over to the phone attached to her wall, and called Daniel. After hearing pick up the phone, she simply stated, "Send the search party he left."


Jack walked through the corridors' playing childish pranks, flicking hats off, playfully tapping soldiers on the shoulders making them turn round as he pulled faces at them;

scaring those not privy to information, with floating coffee mugs and turning off the light switches.

He eventually found Teal'c and decided to even the odds with a few boxing and sparring matches. He managed to land quite a few blows until the big man easily adapted.

Jack soon got bored of that, so started scaring people again, until he was caught out By General Hammond who firmly scolded him. Sulking at the big man putting an end to his antics he headed back down to Carter's lab. He sneaked in slowly before skilful placing his hands around her waist making her jump.


"So essentially, what I think happened is that you were bombarded by the particle field being emanated by the clocking generator..." She moved around her desk, excitedly going full Kid in the candy store. "See, you were in the engine room standing next to it when the device turned on. That would account for the traces of radiation we've been picking up. But the good news is. I think I've found a way to reverse the process. We have to go back to the mother ship and get the clocking generator."

Not hearing or seeing Daniel standing in the doorway she jumped when he spoke.

"Sam who are you talking to?" he said folding his arms.

"Colonel O'Neill. I was explaining how we'll make him visible again." She turned back smiling back at Jack.

Bowing his head in frustration he replied. "No you're not Jacks in Hammond's office."

"I can't believe he did that to me again!" she said spinning around to Daniel hitting the side of her desk with her palm.

"Yeah you know getting that clocking generator off the ship will be the least of our problems. Now getting Jack to help that's gonna be the hard part." Daniel said waving his hand over the chair proving to himself and Carter that the chair was in fact empty. Proving his point he sat down.

"Oh don't tell me."

"Oh yes, he likes being invisible."

"You know, as much as it pains me to say it would be a huge advantage. He's becoming very annoying its grating on my patience." Sam said honestly.

"Hey if he's going to listen to anyone, it will be you."

Daniel left the chair placing a comforting squeeze on Sam's shoulder as he left.

"Great." She said to herself.


"But Sir, think how much of an advantage it would be, they would never see me coming. C'mon If you were in my shoes, you'd be saying the exact same thing." Jack frustratingly said.

"Colonel since you've been back, I have received countless reports of ghostly activity in the base."

General Hammond said exhausted by this conversation.

"And you're point Sir. No one can see me."

"Colonel I have had to spend the entire day informing people that you are under alien influence and that you are the culprit behind these assaults."

"Assaults I'd hardly call it that." Jack mused.

"Tapping air on the soldiers, barging past them, removing caps... Need I go on?"

"Fair point." Jack said after a minute of reflection.

"Jack I know, you are having fun this is quite serious. Come in Major."

Major Carter walked through the door, looking just as annoyed as Hammond.

"Colonel, Sir. I've figured out how to turn Colonel O'Neill back to normal Sir with your permission we need to go back to P05-964 and retrieve the clocking generator of that ship. I believe once we find it we will be able to correct the situation."

"Excellent news Major, Colonel I am ordering you and SG-1 to go through the gate and retrieve the device." He said presumably looking at Jack. "Colonel?" This time George getting more angry and frustrated in his 2IC.

"Um, I think he's left Sir." Carter Said uncomfortably.

"Fix this, Major. Or I'll have no choice but to court martial an Invisible man."


Jack tried to escape, not fully he wanted to at least have some fun before he turned back to normal. He sneaked past the guards and with the help from a unsuspected airman he used his truck and dog to at least freak the guards out. He opened the window after ordering the airman to hide. In his best Military he spoke to the guard on patrol. He moved the dog's head which held his card and spoke.

"Just had to pop out on a covert mission, top secret above your pay-grade. Let me back through."

The look on the airman's face was priceless he couldn't have gained that reaction on his own.

The fun soon ended when they placed a call to General Hammond asking if a dog had permission to enter.

Jack headed back down to the base about to go and see Hammond for his reprimand instead he stumbled upon Daniel giving a briefing to other 'geeks' about his new found universal language. A perfect opportunity presented itself once more.

"And so by translating this tablet, we should be able to determine the most important thing in the universe." Daniel wrote on the white board behind him some essential formula for understanding the basics of ancient numerical order.

He stopped when he heard a loud snore; he didn't even have to turn around to know who it was. Turning around looking at his fellow companions he eyed them up. Just in case it was one of them, albeit highly unlikely.

"Everyone just wanna poke around, see if you can find him?" Daniel sighed.

By this point almost the entire base was up to speed, on what, rather who was the cause of the strange events.


Sam was desperate for a shower, the past twenty four hours had been very stressful. Not only was she annoyed at her Colonels impromptu behaviour but also because the way he acted around her sent her into overdrive.

They had been trying to covertly date for the last year now. At first it started as just keeping it in the room, trying to ignore the feelings – duty above all else. After their failed memory stamp, of becoming Thera and Jonah it became harder and harder to ignore it. In one way it was a blessing, another a curse. They had touched the forbidden fruit, felt what it would have been like together. If only the memory stamped work at forgetting the new memories as well, life would have been simpler, a lot simpler. They wouldn't have to ask their friends to keep their closely guarded secret. Which they both abided by and done so above the call of duty. It was more difficult for Jack and Sam, the switch between lovers and subordinate. Had at first become quite a challenge. They kept things professional at all times, putting their feelings aside in order to protect Earth and it's many allies. Although, it was times like these that became hard, a bad mission or something happens to one of them out of their control; it takes its toll on the other.

Sam got to the woman's locker room, praying that the showers were empty; all she wanted was a nice peaceful shower. She felt clean. There was something about the cascading water droplets, the high pressure just made her relax instantly. Like a full warm exhilarating body massage. Nothing is quite like it.

She got her self undressed and wrapped a towel elegantly around herself, turning the tap on she waited until the water quickly became hot, not a scalding hot, a healing comfortable hotness. Removing her towel she stepped in closing the curtain with her in one foul swoop. She closed her eyes, bent her head back and just sighed in blissful relief, as though all her pent up stresses was washing away from her.

Suddenly this odd feeling washed over her, the feeling she was being watched. No she was being watched. Of that she's sure. She pokes her head through the curtain, pulling it close under her neck.

"Sir, are you there?" she searched the room, for any given clues.

"Nope!" Jack replied.

"Sir, get out. I'm trying to relax here." Sam shouted quietly.

"I could help you with that, you know." He winked, why he doesn't know as she couldn't of seen it.

"Argh, you know I hate it when you are like this. I'm not in the mood for it Sir." She said through gritted teeth.

At this point Jack got up and opened the curtain slightly.

"I'm sorry Sam, It's not every day you become invisible." Jacks apology was sincere.

"Jack, you know you can't stay like this forever. It would be have very, VERY negative effects if you did." Sam signed trying to gage where is face was to emphasise my point.

"Ah, yes well you made your point. Don't suppose I could you know, jump in with you."

"Yeah, when I can see you again. Get out!" Sam squatted him somewhere, although she wasn't sure where.

Jack got the hint, he had been very childish today, he couldn't help it, it was his way of handling tough situations. He sighed deeply. He moved his hand to cup Sam's face. He nodded in agreement. Forgetting that she couldn't see him he spoke up.

"You're right Sam, I'll tell Hammond right now."


On his way back from General Hammond's office, after getting the go ahead, he grabbed a coffee while running into Teal'c.

"You cannot remain this way O'Neill." Teal'c confirmed.

"Why not? It gives us an advantage over the Goa'uld I can sneak around all I want totally undetected. I give us the element of surprise. The bottom line is. I can do more for this planet invisible. Than I ever could as my own sweet salient self." Jack took a sip of his deviously refreshing coffee.

"I assume I am staring at you stoically."

"Not buying it, eh."

"No. You are most transparent, O'Neill." Teal'c had been practising his Tauri humour.

"Oh! I get it. Good one." Jack said Sarcastically.

"I can see right through you!" Teal'c said almost smiling.

"Don't push it."


After Jack finally being on ball with turning back to normal again, it wasn't long before he and the rest of SG-1 were standing at the bottom of the Gate. Jack went through first, taking out a few straggling Jaffa's. He sent the clear code through the Gate and watched while the rest of the team came though. He couldn't help but think 'I told you so'.

After a short hike the managed to get to the Tel'tak. It was Sam's turn to lead the way. Undoing a control panel she rewired the controls bypassing the sequence code to get the rings to activate.

Jack said he'd go first count to Twenty and follow him.

He had taken a small number of Jaffa by surprise. Knocking them out to the floor; he didn't stop there he decided to carry on through both corridors, taking out any stragglers that crossed his path.

He heaf the rings snap into life once more, and started waving at Sam to get her attention. He realised slower than he should of that they still couldn't see him.

"Hello? Hand signals! I'm waving you over." Jack hissed.

Sam shrugs at this comment, rolling her eyes in the direction of Daniel. They quickly get to the Clocking generator. In no less than thirty minutes they found themselves back at the gate room, and then headed straight to Sam's lab.

Jack moves to sits into the swivel chair, starting twirling himself around. Daniel and Teal'c watched cautiously over the chairs movement. All while leaning on Sam's desk watching tentatively, while Carter worked her Doo-hinky brain of hers.

"Okay I've made the necessary adjustments. All I have to do now is initiate the sequence.

Jack "Okay let's do it."

Sam hits the sequence buttons the lights flicker and the power goes out, leaving the base in total darkness.

"Carter?" O'Neill hissed.

"The backup generators will be up and running.

"Oh, yeah this is much better." Jack hyped,

Within a moment the power game back on. So did O'Neill's opaque self.

Thanks for reading.
