The automated gate system alarm started to go off, interrupting SG-1's briefing.

"Unscheduled off-world traveler! Unscheduled off-world traveler!"

General Hammond and the rest of the SG-1 team immediately proceed to the control room.

"It's SG-1's authorization code, sir."

"That's impossible. SG-1 is here."

A realization suddenly popped into Sam's mind. There had been a time prior, involving time travel, when SG-1 used their authorization code to send a note back in time.

"Sir, I think we should open the iris."

"Are you absolutely sure, Major?"

"Definitely, sir."

"Ok. Open the iris and stand ready."

SG-1 immediately files down the stairs to the embarkation room with General Hammond in tow. A beautiful girl, approximately 16, with golden blonde hair and remarkable blue eyes steps through.

"Please, don't shoot. I come in peace with a message."

"Lower your guns."

"My name is Caden Rosha O'Neill."

Everyone turns their eyes towards Jack.

"Oh no. Don't look at me. I don't know the kid."

"Indeed you don't, Colonel O'Neill…at least not in this point of time. I have come from the future to deliver an important message."

"I guess we are all just curious at your name."

"I will explain that in time, but first I must heed you a warning. SG-1 is about to embark to PX-509. You must not go. The team returns carrying a deadly virus. Dr Frasier finds what she believes is a cure, but the virus only goes latent. Sixteen years later, the virus resurfaces ultimately leading to the death of all four of the original members of SG-1.

The SG-1 team just looks at each other in shock. General Hammond turns to their gate expert for a response.

"Major Carter, is this even possible? Is there the slightest chance this girl could be telling the truth? "

"Well, sir…"

"I do not mean to interrupt, but I assure you it is possible. My parents warned me that you might not believe me, so they sent along a note for Major Samantha Carter.

"This just seems so foreign to us. You have to understand our doubts."

"No offense, General, but from what I've heard of the SGC, your day is filled with foreign things. Now, I assure you, the note will explain everything."

Sam just stares at the girl. She seemed so familiar somehow. There were these unexplainable feelings surrounding her.

"General, I think we should listen to her."

"And why is that, Major?"

"Because I have this nagging gut feeling that she is important to me in the future. I feel I can trust her."

Caden hands the notes over to Sam. For a brief second, their eyes meet, and a shiver runs down Sam's spine. The General, along with two men, come to escort Caden to the guest quarters until further questioning. She gasps as she opens the letter to see her own handwriting starring back at her.

Sam

I know this is hard to believe. I remember the mission to PX-509 very well. We all barely returned with high fevers and chills. Dr. Frasier worked hard to find a cure. I did the best I could to help, and eventually we found what we thought was the solution. Indeed, it seemed to work perfectly. For sixteen years, there was no sign of the virus. Then, out of the blue Daniel got sick followed by Teal'c. Jack and I were the last to get sick. Dr. Frasier found the same virus in our systems. Daniel and Teal'c have already passed away. I am afraid that Jack is next. He is already in a coma. I know time is running out for me as well. We have told Caden everything, and she is prepared to go through the stargate if we should happen to die in order to warn you. If you are reading this letter, then it is safe to assume Jack and I have already passed away. Please, listen to Caden. I have faith that if you just look in her eyes, you will have all the proof you need to trust her.

Love,

Sam

She just stands there in silence. They all are curious to know what the note reads. Jack was growing inpatient.

"Carter?"

"Yes, sir?"

"What does the note say?"

She hands the note over. Jack begins to read it.

"I think the girl is telling the truth, sir."

"And why is that, Carter?"

"Well, for one, that definitely is my handwriting. Second, I just can't explain it, but I have these unexplainable feelings that I know this girl somehow."

"I know what you mean. I get the same feeling, but I know for a fact that I have never seen that girl before in my life."

"I know. That's why I can't explain it, but don't you think that it could be possible that if she is an important person in our future that we would get a feeling of familiarity by seeing her?"

"I don't know, Carter. I try not to think about complex things like that, but I will talk to General Hammond. I think we should at least postpone our mission to PX-509. We will keep the girl here, as our guest, and observe her as much as possible. Then, we would be able to reassess the situation."

"Good idea, sir."

They didn't see General Hammond standing behind them in the doorway.

"I think that is an excellent idea. Permission granted. We will wait one week and then reassess whether or not to visit PX-509. In the meantime, try to figure out who in the world this girl is and how she got involved with the SGC."
