Timeline: BtVS: Early seasons & SG-1: After Jack became a General.
Author's Note: Written for Day 11 of the 2022 August Fic-A-Day.

Everyone else was already in the conference room when Buffy and Teal'c arrived. General O'Neill was at the head of the table again with Carter on his right. Daniel was on the man's left side, and on Daniel's left was Colonel Mitchell. There was an unknown black-haired woman with low ponytails on Carter's other side.

Teal'c went for the seat next to the unknown woman so Buffy went to sit next to Mitchell. Everyone in the room followed her with their eyes and she kind of felt like she should've put on some kind of show, instead of just walking over to an office chair.

As soon as her backside hit the faux leather the old guy began talking. He started off by introducing her to the new woman, she was another alien named Vala Mal Doran. Buffy wriggled a little to get comfortable as it mostly just sounded like blah, blah, blah to her ears until he let Carter reveal her findings.

"I'm not sure how you will take this," the woman prefaced her revelations, "but there isn't an alternate version of you in this reality. While I was able to find your mother and her family, your father was killed in a hit-and-run accident back in the late '70s. Your mother has been married and divorced twice, and has one child from each marriage. As far as I've been able to tell, she is currently single."

Buffy stared into thin air as her mind erupted into chaos. Her parents had (probably) never been a couple, and she didn't exist. Her mother had been divorced TWICE! The universe wouldn't be mad at her after all! She had, um, alternate reality half-siblings? Was that even a thing?

Clearly, she had taken too long to react verbally because when she refocused the entire group was staring at her in worry. "I'm fine, really."

"So," Colonel trying for levity, "freaked out, insecure, neurotic, and emotional?"

"No," Buffy replied, "fine as in I'm okay. Well, not okay okay, but I need to process this and then I'll be okay."

In an attempt to steer the attention away from her mental health and the shocking news, and at the same time ignoring that Daniel was explaining the acronym to the two aliens, she asked Carter a question. "Does this mean that the universe won't eat me for being in the wrong place?"

A complicated series of emotions played across the woman's face before she settled on genuine happiness. "It does. Since there isn't another version of you and there never has been, you're safe. Even if we are not able to figure out which reality you come from and send you back there, you can stay here and have a good life. Depending on your career choice, you might even be allowed to work for the SGC."

A warm feeling spread inside of her despite the news of her lack of existence here, and the lack of good news about getting her home. She had someone here who was willing to take responsibility. It might not be any of the people sitting around the table, but they would make sure someone did.

Then something Carter said stopped her thought process, "What's 'SGC'?"

It was Daniel who answered, "Stargate Command. It's what this place is called. The 'big circle thingy' is called a Stargate or a Chappa'ai. In case you missed it in all the excitement, we use it to travel to other planets."

"Yeah," Buffy confirmed, "I got that part when the bad aliens decided to stop by for a little kill and run fun."

She decided it was time to stop circling around the big pink elephant in the room, so she decided to ask the questions. "What happens now? To me?" Then as she thought about it some more, "Will I even be allowed to see my mom and, I guess, my alternate reality half-siblings?"

"Your mother and half-siblings are a hard no," General O'Neill replied decisively. "They can never know about you and where you come from." Then in a kinder voice, he continued, "We're not entirely sure where to put you, so for now you'll be staying here while we figure that out."

He scrutinized her for a moment. "Just, please refrain from stomping on some of my people's fragile egos. Do you have any idea how much paperwork that can cause for me if they decide to complain?"

She smiled innocently, but her eyes glinted with mischief. "No promises."
