Jack had been napping peacefully, until a rather shocking dream had forced its way into his mind, subduing all pleasant unconscious mental activity instantly, replacing it with something far more disturbing... especially since the two people involved were still off world.

It had taken place on their return... or rather, during their return. He was concerned, considering Sam and Jonas' experiences, which were similar to his own.

He strode to the control room, glancing at his watch as he walked. They were due to return to Earth in ten minutes.

Jack wanted to be in the Gate-room when they got back, to check they were okay. His nightmare -of sorts- had had him a little thrown. The origin of it was unknown, and he was hoping that the two off world members of SG-1 would be able to help in that area.

In no time at all, he was opening the door to the embarkation room, pocketing his access card after using it. He nodded up at General Hammond and the officer operating the Gate. They were expecting the return as well as Jack.

It was at that moment that the ring on the Stargate began to turn, making its usual grinding noise as it moved, the chevrons lighting up systematically as they normally did.

Good, so far so good.

Teal'c made his presence known by stepping up beside O'Neill, and bowing his head partially to the Colonel. Jack smiled wanly. He wouldn't be happy until Jonas and Carter walked through that Gate in one piece, perfectly fine.

The Gate exploded into life, bright blue light reflecting off every surface. The metal iris leapt into action, spinning into position.

"We're receiving an SG-1 iris code, General," Jack heard the officer say.

"Open the iris," General Hammond ordered politely, and Jack heard the whirring of the metal device as it swirled out of place, allowing the team access.

Jack was about to speak to his Jaffa friend when a high-pitched whine caused him to whirl immediately, eyes wide in horrific recognition.

Crackles of electrical energy weaved their way around the Stargate's exterior, causing the Colonel to wince, and look up at Hammond in a slight panic.

Teal'c moved towards the Gate, ready to give aid in anyway he could. Jack gripped his arm slightly, gently, but defiantly telling him to stay back.

Without warning, a figure hurtled through the event horizon, about six feet above the ground, followed closely after by another. They crashed to the ramp, landing awkwardly, before rolling to a stop.

Jack immediately ran to their assistance.

"Medical teams to the Gate-room!" he heard Hammond thunder into the microphone.

Help was on the way.

The first figure tried to push their way off the ramp, wincing in agony, and using only one arm for aid. The other was held slightly up, and it shook rather unnervingly.

"Jonas!" Jack called, jogging up the ramp, skidding to a halt by the young man's side, kneeling instantly, lowering his head to try and look him in the eye. "Jonas, are you alright?"

Jack laid a hand on Jonas's right shoulder, and the alien gave an abrupt cry, shaking his head. His eyes remained closed, and he clenched his teeth.

Jack's eyes travelled to the second figure, who lay motionless on the ramp a few feet away from Jonas, who remained in his table-like position, one arm up, head lowered, breathing slowly, trying to ease the pain that was obviously troubling him.

"Sam!" Jack bounded the short distance, and he felt for her pulse, which he located without a problem. Good... at least she wasn't... he couldn't bring himself to finish that subconscious sentence.

Teal'c tried to help Jonas to his feet, but the Kelownan protested, and denied the Jaffa to give him assistance. Teal'c acknowledged, and merely stood aside as the first medical team rushed in, and straight up the ramp to Jonas.

Dr. Fraiser was one of the team, and she stopped by the man's side.

"Jonas, you really have to be more careful," she teased lightly, touching a hand to his arm gently.

Jonas winced, but stifled a cry.

Jack reluctantly moved aside from the unconscious Carter as the second medical team brought a stretcher to her side, and proceeded to load her onto it carefully, handling her gently, so as not to cause her further harm.

Siler stood to one side of the ramp, and Jack saw an opportunity to demand answers.

"What the hell was that all about?" he barked authoratively.

Siler shook his head hopelessly. "I'm not certain, sir, but I think we had a system overload. The incoming wormhole was supercharged..." he trailed off with a shrug.

"Get on it," Jack grumbled, walking over to Jonas and Fraiser as the two stood, the former cradling his arm.

"How bad is it?" Jack inquired with concern, looking the pained man in the eye, as Carter was carried past.

"I think he's dislocated his shoulder, Colonel. It'll be fine when we get it back into place," Fraiser reported, giving Jonas a reassuring look as he eyed her unsurely.

"Don't worry," she told him calmly, leading him out of the room, Jack in tow, "it's not as bad as it sounds."

Jonas turned his head to look at Jack, who merely shrugged.

* * *

After overcoming the initial searing agony that had followed his shoulder being pulled back into joint by the Doctor and a couple of her assistants, Jonas had laid pretty stationary for a while, getting his composure together again. The pain had been intense, but it was passing now, and his arm was in a sling, restricting his use for a while.

Fraiser had insisted to him that he needed it, but not for long, it was just a precaution, as she called it.

Jonas didn't know whether to believe her or not. He had never dislocated his shoulder before... and he never wished to again.

Jack was sitting near to him, watching Carter intently as a nurse checked on her.

The nurse looked up as she felt the eyes on her, and told O'Neill, "She has mild concussion. She'll be perfectly fine, sir."

With a single nod, the Colonel turned back to Jonas, saying, "So, what happened on your end?"

Jonas went to shrug, but resisted the urge, and settled for shaking his head from side to side. "We dialled the Gate, and Sam sent through the iris code. We headed through the Gate, and were just thrown out on this end. I don't know what happened."

"So nothing hit the Gate on the other side?" Jack inquired curiously, approaching the puzzle from as many angles as he could think of.

"No, not that I know of," Jonas told him, with another shake of the head, as he looked down at the sling which held his right arm. He felt a little useless right now, but as soon as he was able to take it off, he would. He wanted to get back to work as soon as possible. This problem needed his undivided attention.

O'Neill sat silently in thought, before he came out with, "So, what did you find anyway?"

Jonas embraced the welcome topic of something other than their recent -and rather unpleasant- journey back home, and replied quickly, "We found traces of naquadah in the metal alloy that the vent covers are made of in the chamber we were sealed in."

"Meaning?"

Jonas smiled. "These people don't have access to naquadah. Their primary metal alloy is steel. Which means someone else created the vents leading into that room. Probably the same person that sabotaged the Gate."

"Sabotage?" Jack repeated quizzically, cocking his head in a confused manner.

Jonas took a moment to consider what he was about to say, before actually saying it aloud, "If there wasn't a problem on the side we entered from, then something must have been done to the Gate on this end." Then he added once again, "Sabotage."

"Yeah, but..." O'Neill faltered, then, eyes narrowed, said, "by who?"

Jonas shook his head slowly, deep in thought. "A Goa'uld?"

Jack's back straightened immediately at the mention of the Goa'uld, and his demeanour became more professional. He was on the alert.

"We expect it's a new Goa'uld we haven't heard of who has the same invisibility technology that Niirti had, but their actions are much more subtle than hers were. They're trying to confuse us," he explained, his voice quiet in the almost silent room.

Jonas looked over at Sam as he listened to the Colonel's words, "I'll say. All these nightmares..."

"What?" Jonas' head snapped back to face O'Neill. "You had a nightmare too?"

O'Neill looked a little taken aback at the abruptness of Jonas' tone, but he nodded. "Yeah. And then you two got thrown through the Gate... just like I dreamt."

Jonas swung his legs cautiously out of the bed, careful not to kick the Colonel square in the face. "That makes three of us. I've had a dream, as has Sam, and now you have too."

"And we were all in the room," Jack concluded, to which Jonas abruptly nodded his confirmation.

Jack was starting to piece it all together, albeit slower than Jonas had.

"So, it's just Teal'c who hasn't had his nightmare yet," O'Neill offered, standing, and watching awkwardly as Jonas hopped off the bed's end, landing firmly on booted feet.

They cast a joint glance at the unconscious Samantha Carter, before Jonas said, "Let's hope he doesn't need sleep for a while."

The two headed for the exit together, after one last look towards their friend.
