Jack walked down the hallway of the SGC, not sure what to do with himself. In another reality, he had another kid. A beautiful baby girl. Painful memories coursed over him. He thought that he would have been ready for something like that. After all, he had let the Reetou kid call himself Charlie.

But that was different. He knew he wasn't ready to have another kid. But in another reality, he had another kid.

That was, if Charlie had even been born in the first place.

The very thought of these Alternate realities made his head spin. What if he had never met or married Sara? What if Charlie had never been born because he had never met Sara…

He was so confused.

He passed Sam's lab and stopped. Maybe she could explain it to him better. He walked into the lab to find it empty. In fact, it looked as though no one had been there for the last few hours. Where was Carter? He asked himself.

Sam stepped out of her quarters, sniffling. It was time to get back to work on her report of the new naquadah reactor. Hopefully, she could finish that today and get it to the eggheads at Area 51. She smiled. The Colonel was rubbing off on her. She closed her eyes. Undoubtedly that was how General O'Neill's relationship with his wife had started. Simple things like calling the scientists 'eggheads' and saying things like 'for cryin' out loud.'

"Carter!"

She took a deep breath. This was obviously her Jack, the other Jack had called her Samantha.

"Sir?" She asked, turning as she hoped that her tears were no longer visible.

He stopped. "Carter, you okay?"

Damn, she must look like she'd been crying. Not a way to keep up the super soldier image. "Just fine."

"You sure? 'Cuz I've been trying to wrap my head around this alternate reality thing and it's…well, it's confusing me."

"And you'd like me to explain it to you?"

He eyed her red, puffy eyes with trepidation. "Carter, I can come back later if you want."

She smiled. "Don't worry about it. Just had a little run-in with General O'Neill."

"Run-in? If that jerk hurt you…"

"No." She responded, quickly. "No, he was the one who was hurting."

"His wife?"

"Samantha Carter."

He closed his eyes. "Damn!"

She nodded. "I guess she looked a lot like I look now. It…it really threw him for a loop."

"Oh."

"How are you doing with this twin thing?"

He opened his mouth. "Well…it's…messing with my head too."

"Really?"

"Yeah. I mean…never mind."

"He kissed me, you know."

Jack looked up. "What?"

"Yeah. I got the distinct impression that he wanted more than that, but…not with me. He wanted to make sure that she was still there, and…I'm not her."

"You okay?"

She smiled, sadly. "I guess, I just don't know how to help. I feel like I'm just making the situation worse."

"Carter, you could never make the situation worse."

A tear fell unchecked from her eye. "I think I already have."
