An hour later, SG-1 assembled in the debriefing room. General Hammond motioned for them to sit down. "Sir?" Sam asked, noticing the furrows on his forehead.

"I'm fine Major." He said. "Is it possible?" he asked bluntly.

"Yes sir." Major Carter replied. "I don't know how they did it, but SG-1 has traveled back in time before. It's entirely possible that they have too."

"Alright." General Hammond said, and turned to Teal'c. "Can you be absolutely certain that that is your son?"

"Yes, General."

"That's what I thought." Hammond muttered.

"Sir?" called a voice from the doorway.

Hammond turned to find Dr. Janet Fraiser, the SGC's chief medic looking at him. "I think you should see this."

Hammond nodded and rose. Once they were outside, Hammond turned to her. "What is it Janet?"

"I got the blood work back ten minutes ago, sir. And it confirms what we know. That is indeed Cassandra, although she is approximately 25 years older than the one we know."

"But what's more," she continued, "is that the others all seem to have DNA that matches one or more members of SG-1."

"What are you saying, doctor?" Hammond asked.

"What I'm saying, General, is that those people I have in my infirmary are my daughter Cassandra, Teal'c's son Rya'c, the son of Colonel O'Neill and Major Carter, and the daughter of Dr. Jackson, and well . . . myself, sir." Janet said in a rush.

"What?!" Hammond cried.

"I've double and triple checked the tests, sir. There's no other explanation." Janet said.

"Order the Captain to bring them to the debriefing room, doctor." Hammond said darkly. "I want some explanations, and I want them now!"

Ten minutes later, the strangers had all joined SG-1 at the table, and General Hammond was looking confused and frustrated. The hologram of an older version of himself had dispelled any doubts he had about the strangers.

He turned to glare at the blond haired stranger. "I want an explanation Colonel."

"Yes, sir." She said. "But I believe Dr. Jackson would be a better person to give it."

"Me?" Daniel blinked.

The young brunette smiled. "No, she means me."

"You?" Daniel looked confused.

Catherine smiled sadly. "My name is Dr. Catherine Jackson." She began. "I have a Ph.D. in anthropology and linguistics. I come from the year 2027, which I believe is 25 years into your future. I am the daughter of Dr. Daniel Jackson and Dr. Janet Fraiser, of the former SGC. I am twenty one years old."

She paused and looked at the shocked faces around her, until she caught Scott's grin. "This is Major Scott O'Neill," she said pointing to him, "of the former United States Air Force. He is the eldest child of Colonel Jack O'Neill and Major Samantha Carter."

She almost smiled at the gasp coming from Jack. She also noticed Sam had gone pale and was looking everywhere but at the Colonel.

"I believe you know Colonel Fraiser and Rya'c." Catherine took a deep breath. "25 years from now, the Goa'uld have all but wiped out the Tok'ra and enslaved Earth. There is a small pocket of resistance that is forced to run and hide from them."

A shadow crossed her face. "One that was destroyed just before we went through the gate."

Scott reached over and squeezed her hand. She smiled softly at him before continuing. "The Asgard were severely weakened from their war with the replicators, and couldn't stop the Goa'uld when they began to invade other planets. Before we knew it, the Goa'uld had captured planets within striking distance of Earth. They had an army on our doorstep. It was only a matter of time before we fell."

"The SGC tried everything it could to stop the advance, but nothing worked. After a while, the truth was given to the general public and the armed forces scrambled to get ready for an invasion. But we were no match for the united Goa'uld."

"Earth fell, and the ones that survived fled through the stargate. That was about 10 years ago. SG-1 died trying to stop the invasion. We tried to appeal for help, but the Tok'ra were almost destroyed and the Asgard couldn't do anything."

Her words were met with silence. Catherine sighed, and Cassandra took over. "We came here for a reason, because despite how it sounds, the Goa'uld are not as strong as they wish us to believe."

"The Goa'uld were so strong because they had formed an alliance. The System Lords are at war with each other, as you know. On one side sits Anubis and those allied to him because of his power over them."

"On the other side stand Apophis, Kali, Svarog and Morrigan. Divided they knew they would eventually fall to Anubis, so they set up an alliance. And began to capture worlds so they could for an army to fight him."

"Unfortunately, Apophis realised Earth would be a threat to them while they were fighting each other, so he convinced the others to help destroy us." Cassandra looked pointedly at the General. "That's why we came back. We have to stop that alliance forming, or Earth will be destroyed."
