"Major!"

Davis didn't stop as he turned for the corner.

"Major Davis!"

Pausing, the liaison halted and turned around. He frowned slightly and his hand slipped to the back of his slacks.

A red-faced tech panted as he jogged up to Davis. "We just got in the taps on the phones, sir. Sorry they were late. Had a tough time trying to get our tracking reports for some reason." The tech was practically dancing in place, excited. "A call came in a few minutes ago, too! We hadn't read all of the details of the call yet. I thought I better get it over to you or Major Carter as quick as I could." A stack of papers waved at Davis.

Major Davis lowered his hand and smiled, accepting the report. "Thank you, Lieutenant," he scanned the nametag. "Vant. I'll bring these to the major myself." Davis tilted his head at him. "Dismissed."

The technician looked disappointed that the major hadn't reacted in the same level as he did. Muttering a goodbye, the tech left Davis standing in the hallway.

Checking around the hall, Davis calmly entered a nearby room, an empty bunk no on was using at the moment. Quickly, he scanned the pages until he reached the last one. His gaze narrowed as he read the last few lines, Jackson's number and where he called listed as the most recent transaction. Calmly, he detached the last page off the stapled stack and ripped it up to tiny pieces. He stared at them piled in his palm before flipping his hand down and watch them float down to the wastebasket. Davis rifled through the pages once more, nodding to himself as everything seemed to be in order. Then, he slipped out of the room. Davis spotted Siler walking down the hallways. What was his name again?

"Sergeant," Davis called out. The engineer halted mid-stride and pivoted around towards him questioningly.

"Yes, major?"

"If you see Major Carter," Davis said smoothly, "Would you mind giving these to her? The major had been expecting these. Nothing much to report though."

Siler gave a brisk bob of his head. "Sure. Have to give her our findings from the auxiliary base as well."

"Anything of interest?"

The tall engineer shook his head.

Pretending to sigh, Davis nodded his thanks. He watched Siler head off to the hallways for a long moment before he headed for the elevators. Punching the level he needed, Davis smiled tightly just as the double doors closed.

Sam could see Teal'c's stoic expression off her monitor. While the Jaffa had given nothing away, finding out from the techs that they're still checking, had no new updates on Daniel or the colonel, had been a defeating blow. Teal'c had been pretty much incommunicado the past ten minutes and while the colonel may think Teal'c just doesn't talk much, she had come to read his expressions very well over the years. And the frown told her to leave him alone.

Mentally, she sighed. She had returned to her office, Davis gone, and set out on working the tapes, starting from the hour leading to the attacks. And the reports were right. There were no signs of forced entry. In fact, there weren't even signs of any of the men in the tapes. So how did they get past security? As primitive she had first gauged the auxiliary base to be, she knew in reality, security was very tight, even before they made the new additions to accommodate such a load of prisoners.

"Final tape they had, basically the last few minutes before the break-in," she murmured as she slid the last tape in. Sam stretched out, her neck aching from staying in one position for too long. "Teal'c, maybe you should stay with General Hammond and help out with the interrogations." She kneaded one knot on her shoulder.

"I do not agree," rumbled Teal'c.

Surprised, she turned around.

The dark alien frowned. It sent a cold shiver down her spine. "It would be for their safety I do not participate in the interrogations."

Now Sam frowned. "You mean the general?"

"No…the prisoners."

Oh-okay. As her CO would put it, someone was having a very bad day. Recalling how the general had accidentally slammed the phone down too hard when one lead resulted in just wasting minutes, everyone was having a very bad day.

Most of all, the colonel and Daniel, she thought as she fiddled with the controls. Images whizzed by. Sam straightened as she spotted two men in black jumpsuits. Another one, walking up ahead in the desert camouflage uniform everyone at the auxiliary was wearing, leading the way. What the? She rewound the tape to a few seconds before that. Sure enough, at the camera angle before, three men were nodding to a guard, who gave them a quick glance and waved them through. The three were dressed the same though, the desert camouflage, turning the corner to the first gate. Where were the other two men from before? She tracked the movement until the secondary camera switched over by the secondary gate and then-

"Where did they go?" she blurted out. There were the same two men in the black jumpsuits, the third in the base's colors.

A shadow darkened her screen as Teal'c joined her. "They are not the same people as when they first entered the cells."

Sam nodded. She rewound the tape. Tapping on the glass, she pointed to the two men in question. "There, these two were following him. The guard clearly recognized them, let them pass to the cellblock. So obviously they work on the base. But then…" She paused, waving for the next shot. She freeze frame. Three men, exiting out of the previous corner, had their heads turned away from the surveillance camera. She couldn't even make out a clear profile of any of them. "Here." Sam tapped a finger at the black outfits. "Those were not the same uniforms from before. Not enough time for them to change either." A wave of uneasiness churned in her stomach. "Those look like NID outfits." Sam frowned, remembering. "When Maybourne collaborated the attack to regain control of this base, they had on the same vests, same uniforms." She pointed to the glass with her nail. "I recognized the vest. They had it customized from ours a while back." The major folded her arms and pondered the screen before her. "Good enough proof for me who were involved."

"One remains the same, though," Teal'c noted, pointing a dark finger at the leader of the trio.

Pulling out the reports, Sam flipped quickly through the files of the three missing men. She flipped out one page and pressed it to the monitor next to the leader. A square jawed face, with an extreme buzzcut on the digital photo stared seriously back at them. She compared it to the footage. "There's your missing Ford."

"They match," Teal'c determined. "Yet the other two men were different. How is that so?"

Sam chewed on the pencil she was using. "I don't know. That corner is clean cut, goes from one hallway to the next. There's no room there. Doesn't branch off to any other corridors. None we saw when we were there." Her brow furrowed. "Didn't Sergeant Kent mentioned something about seeing Ford and then not?"

"An illusion?" Teal'c guessed.

Sam nodded vehemently. "If they were within our organization or NID, they would have the same access to our—" Her eyes widened. "Those evidence bags we brought back. The one with the colored glass we found. Where are-"

A clear ziplock bag swayed serenely in front of her. Sam smiled for the first time since the whole ordeal. "You read my mind."

Teal'c replied with only an arched eyebrow.

Opening the bag, Sam spilled its contents to a space on her desk. The shards tinkled as they landed but they didn't break. "Let's see…judging how the edges are, they seem to be from a round object, maybe a disc?" She moved some of the pieces around, shook her head and moved some back. "Great, I was never really good at these puzzle things…" After a few frustrating attempts, she sighed and sat back. "What does that look like to you?"

The Jaffa tilted his head forward and studied the circular outline the device made. "It does seem familiar." Teal'c gave a long "Hm" as he thought it over. "They appear to be the devices the aliens wore who infiltrated the SGC."

Sam snapped her fingers. "You know…you're right! That's why they seem so familiar to me! I had seen one up close only once, after I escaped and met up with Colonel Maybourne." She grimaced at the name. "It's almost like a portable hologram projection device. Now we were able to figure out how they were able to download the images into the device using that large carrier machine they had where they stored all their victims. But how…" She stared at the pieces, expecting them to rearrange themselves to some form of an answer.

Teal'c didn't sound too happy. "If they were able to adapt a Goa'uld communications globe as O'Neill had reported, they may have well been able to do the same with this device."

"Which means," breathed Sam, "NID could have been out there, walking around under our noses all this time. And we would have never known. That's how they got past the guards. They must have gotten some of the base staff and, I don't know, downloaded their images." She waved at the shards in disgust. "Then NID walked right into the auxiliary and no one stopped them."

"It would appear then," Teal'c growled, "perhaps they may do the same here."

Sam shook her head. "We installed those sound wave generators, remember? Once they step through the Stargate back here, they get turned on. The devices would shut down the moment they arrive in the embarkation room. They wouldn't have gotten past us."

"Had they attempted to enter through the means of our Stargate," rumbled Teal'c in a low voice.

She stared at Teal'c. "You're thinking another mole? Here? Besides Makepeace?"

The alien stood there, his lips pressed together, clearly unhappy with the possibility. "Perhaps."

Gathering up the shards, Sam poked at them. "Would explain how they knew where the prisoners were being transported." The more she thought about it, the more troubled she grew. "Come on, we better check the labs. I know we still have the visual files of everything we had cataloged over at Area 51. Let's compare these with this." Abruptly, she rose from her seat, shards in hand. Sure enough, Teal'c followed.
