Let's see if Sam and Teal'c get some info....

Sam knocked twice on the General's door. At the sound of Hammond's voice telling her to come in she opened the door and stepped inside. "Sir," she started, looking around the office to see if they were alone.

"Major, come in. Have you found anything?" Hammond asked.

"Yes, Sir. I think we have," she started, placing the printed documents on the desk in front of the General. "We think Captain Leon Williams is our man. He transferred to the SGC only three weeks after Captain Miller's retirement, Sir. He was stationed at the Pentagon, doing research on biological weapons in the Middle East. Colonel Kennedy took him off this assignment and signed for his transfer to the SGC."

Hammond looked at the information in front of him, silently nodding in agreement.

"What's really interesting is that he was stationed at FIOD before the Pentagon assignment, Sir. He was still a Lieutenant then. Now I have no idea what that department really is, I couldn't find any information on that, but what's really interesting is that Captain Potter has worked there as well."

"Captain Potter?" the General asked sharply.

"Yes, Sir," the Major answered, not noticing the tension in Hammond's voice. "Captain Potter is one of the best technicians the NID has. He's responsible for lots of research on alien technology we bring back from our missions, Sir."

"I think you just found our mole, Major. FIOD is a cover up, fake department. The Air Force registers employees there when they don't want to register their real assignment. Good work. Have you made a list of the planets SG-9 has visited the last six weeks? Found anything?"

"Yes, Sir. The list is right there," she pointed at the papers she'd placed on the General's desk. "Teal'c identified one of the planets as a former Tollan colony, Sir. I think we have something to discuss with High Chancellor Travelle."

"Who else knows about this?"

"Only Teal'c and me, Sir. Teal'c is keeping an eye on Captain Williams right now."

"Mmm. Normally I would put somebody onto him, to watch his every move and see if he could lead us to his superiors. In this case, I think we just have to snatch him and interrogate him. I don't think Colonel O'Neill has lots of time to waste."

"I agree, Sir. Do you want me to bring him in for questioning?"

"You do that, Major. Take Major Ferretti with you for back-up, in addition to Teal'c. SG-2 has returned from their mission this morning, so the Major will still be on base and I'm sure he'd be willing to help. We don't want our mole to escape."

"No, Sir. I'll get right onto it."

"Oh, Major…" the General called her back when she was almost at the door. "Push him really hard. Put the fear of God in him. I want answers and I want them pronto. And let Dr. Jackson contact the Tollan again."

"Yes, Sir."

After having searched the base for Major Ferretti, Sam found him in the infirmary at last.

Louis Ferretti had returned from an eight-day mission off world and had heard the news on Colonel O'Neill as soon as he was back. He sat beside the Colonel's bed, softly talking with Daniel Jackson, who was filling him in on all the details.

"Hi," Carter greeted her colleagues, then checked the still figure on the bed. "How is he?"

"Jack has been sleeping, although restlessly," Daniel said. "He was awake a while ago, but he could barely last ten minutes. Dizziness and a severe headache are the main symptoms."

"I can't believe how this could have happened," Ferretti said, the anger evident in his voice. "We must have another mole in the SGC."

"We do," Sam said. She quickly reported what they'd discovered so far to the two men. "I came to ask your assistance to arrest and interrogate him."

Louis' face lit up. "Anytime, Major. I want to know how that bastard did this, who his contact is and how we can get that damn thing out of the Colonel's head."

"Daniel, the General asked you to contact the Tollan again, to discuss the list of planets SG-9 has been on, especially the one Teal'c recognized. See if you can find anything from that side, okay?" After Daniel's nod of understanding the two Majors left the infirmary, looking for Captain Williams.

Three hours later they had Leon Williams in the interrogation room, had asked him all kinds of questions, threatening him, pushing him to his limit, but the Captain had kept his mouth shut, refusing to reveal any information.

Ferretti had played the 'bad cop' role while Carter played 'good cop', but that tactic had gained them nothing. Teal'c was present, too, sitting silently, watching the scene in front of him with a stoic face.

Ferretti slammed his fist on the table, in front of the Captain's nose. "We know about your connections to Captain Potter and Colonel Kennedy. Now. Again. Who is your prime contact?"

Carter leaned back in her chair, running a tired hand through her blond hair. This wasn't going to work; the Captain was too secure and kept his mouth shut. Ferretti seemed to realize it, too, as he fell back in his chair, outraged at the situation.

A soft drumming noise drew everybody's attention to the silent Jaffa, who bent closer to the table, his strong slender fingers repeatedly tapping the table in a steady fast rhythm. "As the First Prime of Apophis, I was taught many ways to harm a victim with my bare hands," Teal'c stated emotionlessly. Moving his face closer to the Captain, the Jaffa didn't blink an eye as he continued. "Colonel O'Neill has taught me at least a dozen other ways to maim, or kill. I do not think you would like me to show you these methods, though I would enjoy it greatly."

Lou Ferretti observed the sweat that was appearing on Williams' forehead now. The mole shivered unwillingly at the words of the Jaffa, knowing that every one of them was true.

Carter played along. "Teal'c, you can't do that…"

"No, you can't," Captain Williams said, his voice still steady and firm, although they all could see the fear in his eyes. "You all get a court martial for that. This is still the United States, you know."

Ferretti feigned surprise. "Oh, is it?" He looked at his watch. "Hmm, Major," he addressed Carter. "Can I buy you a cup of coffee?"

Carter shoved her chair backwards to get up. "That would be great. I was getting thirsty."

Ferretti rose to his feet as well, without giving the young Captain another look.

Williams shifted uncomfortably in his chair. "Hey! Wait a minute! You can't leave me here, alone with… with him!"

Ferretti briefly looked over his shoulder, without stopping moving towards the door. "This is still the United States, Captain. It's time for a coffee break."

"Besides," Sam added, following her colleague. "Teal'c here will be with you until we come back."

"But…" the Captain protested weakly, noticing how the huge Jaffa slowly pulled his chair closer to the table.

Lou opened the door and stepped outside the room with the female Major on his heels.

"Wait!!!!" Williams pleaded urgently. "I'll tell you all you want to know. Please…"

Carter started to close the door, slowly, without looking back.

"It's some high people at the NID. I worked with Captain Potter, he's my contact, I swear!!!" Leon Williams was almost panicking now, as the Jaffa was looking him straight into the eyes without letting go for one second. "I think it's Colonel Simmons who is the man behind all this, although it also could be somebody else... "

The door, almost closed, slowly opened and Major Carter stepped back into the room. "Colonel Simmons? Why do you think this Colonel Simmons is involved?" she demanded sharply.

The Captain hesitated.

Carter turned around, motioning to walk out again.

"No, wait!" Williams yelped. "Potter is doing some research for Colonel Simmons on alien devices. They were looking for devices which could control somebody from a distance. They had been working on the device one of the SG-teams had brought back from PR4639. They attempted to change the circuits, ran some tests with different kind of power supplies…"

Ferretti and Carter returned, closing the door behind them and sat back down again. Carter looked astonished with the given information. "Holy Hannah, you're talking about that cylinder, with which one can read somebody else's mind?" She turned to Ferretti and Teal'c. "SG-3 brought this back. I've studied it for a short period. It's somehow similar to a hand device, only this device has a switch and doesn't need the power of a Goa'uld. I think this device is called a Shak'ta-na. Are you familiar with that, Teal'c?"

The Jaffa raised his brows and nodded. "I've heard of such a device, Major Carter. But I have not seen it in use."

Sam turned back to the Captain on the other side of the table. "Are you trying to tell us that the NID has been trying to invert the mechanism, in order to write in someone's mind instead of reading from it?"

The Captain nodded, wiping the sweat from his forehead. "Yes. I think they came pretty close to the solution, although it didn't work completely. Captain Potter was unable to make it work from a distance on a subject."

"That's why they needed that Tollan scientist, then," Carter said to Ferretti.

Williams looked back at them, surprised that these people were so close. "Yes. Somebody provided Potter with the name of that Tollan guy. All they had to do was to contact him. For that, they needed somebody within the SGC, who was free to travel through the Stargate with one of the teams in order to make the contact and gather the needed information."

"So they sent you," Lou Ferretti joined into the conversation.

"Yes, Sir. I had been working for FIOD serving Captain Potter, so we knew each other well. It was all a matter of paperwork to get me transferred from the Pentagon to the SGC."

"Colonel Kennedy signed for that," Ferretti nodded in understanding.

"Does Colonel Kennedy know about the research the NID is doing?" Sam asked.

"I think so. I think he's the one pulling the strings.

"How did you contact the Tollan expert?" Ferretti wanted to know.

"That was easy, Sir. SG-9 was scheduled to visit a planet from which I could contact the Tollan rebels. I knew the next planets we were scheduled to go to, so I left the addresses with the rebels and they arranged a meeting with Dr. Travis for me on one of them. He gave me the schematics, instructions and a sample device. In return I had to hand him a list Captain Potter provided me with. I have no idea what it was, I swear. But it seemed to please Dr. Travis a great deal."

"Do you know what Captain Potter did with the schemas and instructions?" Carter asked.

"He managed to build a prototype, Ma'am. They used a dog as the test subject for the probe, planted it in its brain and tested it thoroughly. Apparently it was a success because the next I heard was that they'd found a human volunteer for the next round of tests."

"Volunteer?" Teal'c barked.

"Yeah, well," Williams stumbled. "I didn't know any more than that. But when I found out Colonel O'Neill was the one implanted with the device I knew he wouldn't have volunteered for it."

"Ya think?" Lou Ferretti shot back, angrily.

"How did the NID manage to catch the Colonel?" Sam continued, smiling softly to herself at hearing Ferretti using an all too familiar expression.

"I don't know, Ma'am. I was ordered to observe the Colonel's reactions the last couple of days and report it back to Captain Potter."

Carter eyed Ferretti. "I think we've got the picture complete, Sir."

"With all due respect, Ma'am. Now that I've laid all my cards out on the table…I noticed that you'd figured out the Stargate engaging triggered the device. I recently found out that that's not the only trigger."

"What?" Louis burst out.

"Potter told me over the phone that there's another one, Sir. I'm sorry, I don't know what it is, Sir, but there is another trigger. He was very clear on that."

"Damn," Ferretti muttered.

"We have to find out what that is, Sir." Carter looked shocked at her colleagues. "We also have to make sure the Colonel doesn't hurt anybody…"

Ferretti jumped to his feet and called in the guards. "Lock this man up, airmen. Carter, Teal'c; let's go. We've got to brief the General."

So... we know a little bit more now. Still excited?
