Full summary: Carter searches Jolinar's memories for the key to a new function of Goa'uld memory devices. But when the Tok'ra base is attacked and someone dear to her is killed, what will happen when his closest friend comes to warn them of an infiltration attempt? And two Goa'uld who take on Native American personalities threaten everything they thought they knew about the race's history…

Takes place some time before "Divide and Conquer."

"Incoming wormhole," Sergeant Harriman announced over the loudspeaker. He looked over his shoulder at General Hammond. "Receiving IDC, sir. It's the Tok'ra."

"Open the iris," the general nodded and headed down the stairs to the gate room with Major Carter. "Stand down," he ordered to the security teams surrounding the gate as the metal iris spun open.

"Dad!" Major Carter ran up the ramp to greet her father as he emerged through the shimmering event horizon.

General Hammond smiled as they embraced and stepped forward to shake Jacob Carter's hand. "Welcome back, Jacob."

"Thank you, General. It's good to be back. The Tok'ra have a matter we wish to discuss with you." He turned to his daughter. "And you, Sam."

"Me?"

General Hammond moved them to the door. "Why don't we discuss this in the briefing room."

When General Hammond and SG-1 were seated, Jacob began. "The Tok'ra have reason to believe there may be a significant technological advantage on the horizon. One of our Jaffa spies managed to get their hands on a supply of Goa'uld memory devices."

Colonel O'Neill grimaced. "Those damn things they stuck in our heads?"

"Yes."

"I hate those things."

Jacob smirked and continued, "Some of our scientists have been attempting to manipulate these devices in order to not only view, but also alter memory."

"To what end?" General Hammond asked.

Teal'c interjected, "If they are successful, such a device would prove very useful in maintaining the safety of the Tok'ra base."

"Exactly," Jacob addressed General Hammond. "We could also do a much wider search for willing hosts and more publicly spread our cause. Those who meet us with hostility could be taken care of safely and peacefully, meanwhile allowing our alliances to grow in strength. As you know, our numbers are dwindling, and it is nearly impossible to find hosts without compromising security. We believe –"

"Hang on," interrupted Daniel, "Doesn't this bother anyone? I mean, do we really have the right to change people's memories? That's like… it's like stealing their very identity."

"This could be dangerous if used incorrectly or if the devices fall into enemy hands," Teal'c added.

Jacob lowered his head, allowing Selmak to speak. "I understand your concerns, Dr. Jackson. But I assure you, these devices would only be used to erase specific memories that endanger the safety of the Tok'ra or of your own people. As for security measures, only a select group would be allowed to operate the devices. Precautions are already being taken."

"That still sounds like a risky piece of technology," Daniel objected.

"I trust the Tok'ra know what they're doing with this," General Hammond offered.

"Selmak," Carter said, "My father said this whole thing had something to do with me."

"Actually, Major, you may be a crucial part of these experiments. So far, our tests have been unsuccessful. However, Jolinar may have encountered something like these devices on one of her missions. We think there may be something in her memories that could help us better understand how to use them."

Carter nodded slowly, searching for a familiar image. "Nothing comes to mind, but I'd like to try and help." She turned to General Hammond. "Sir, request permission to return to the Tok'ra base with Selmak."

The general thought for a moment before agreeing. "Very well, Major."

"Hey! Hang on," O'Neill demanded. "Much as I'd like to say otherwise, I agree with Daniel. If anything – I mean anything – goes wrong, I want Carter back here ASAP."

"Sir," she interrupted.

"Carter, I mean it. No funny business, no hanging around. We need to know the second something goes wrong."

"As much for the Tok'ra's sake as for ours," Daniel added.

"Of course, Jack," Jacob agreed, now himself again.

"All right, it's settled, then." General Hammond stood up. "You have a go. I expect a report back in 24 hours."
