Two hours later:

"I don't understand why we still have these meetings." Daniel groaned. "It's not like we're going to hear anything new."

Sam chuckled, though everyone could still see her melancholy interior through her light-hearted exterior.

"Be quiet, Daniel." Vala admonished. "Grace called the meeting. Maybe she has something to say."

"Grace Carter has not yet arrived." Teal'c said, observantly.

"Actually..." Grace said, walking in. "I'm here."

"Wonderful. Then we can start." Cam said from where he sat, sulking, in the back of the room.

Grace inhaled. "I know how to get us home." She said, seriously.

Sam's eyes widened in curiosity.

Cam straightened. "You do?"

She nodded.

"How?" Vala pressed.

"I...figured out how to reverse time in a localized field." She said, eyeing her mother levelly.

Sam inhaled sharply as she realized what Grace had found.

Daniel looked at her curiously. "You did what?"

"I figured out how to reverse time in a localized field. We can't do it further back than just before Mom turned on the field; otherwise, it would create a paradox that the system would be unable to handle."

"We don't have enough power to do it, though." Sam said, after a moment. "The power generator of the Asgard core is too far depleted."

"I thought about that, Mom." Grace said, stepping over to the window. "If we let the Ori beam hit us, we can use the energy of the blast to power the reversal."

"How do we keep from making the same mistake?" Sam countered.

Daniel and Vala shared a look with one another. Somehow there was more going on here than they'd been clued into.

"One of...you..." Grace said, choosing her words carefully. "Can stay in a personal shield, and hopefully, you can get home."

"Wait..." Daniel said as understanding began to dawn. "You..."

"I will cease to exist. At least...until I'm born...again..." Grace said, swallowing. "Theoretically, you should be home before that happens."

"What about the Asgard core?" Vala asked, looking at them. "By now, we know that's how the Ori were able to follow us in the first place."

"I designed a program just before Grace was born, that would disconnect the Asgard core in a matter of seconds if I ever figured out how to, uh, get away from the Ori blast alive." Sam said, eyeing her daughter seriously.

"Look, it's your only chance to get home." Grace insisted.

Cam looked at everyone. "Shall we...put it to a vote?"

"No." Sam insisted.

"Mom..."

"Grace..."

"I'm forty-nine years old, and old enough to make my own decision, Mom." Grace said, levelly. "Besides...it's not like I won't be born. You were already pregnant with me when you embarked on this mission."

"But..." Sam argued weakly.

"I want to see Earth, Mom. Like you said, when your pool of experience is limited, so is your potential for growth."

Sam looked at her daughter as tears welled up in her eyes. The rest of the team found their way out of the room so that mother and daughter could have a private moment.

"The date modified tab on the file said January 15, 2048." Grace said, looking at her mother. "You figured it out ten years ago. You could have done it without waiting for the Ori blast to hit us."

"And choose to have my daughter erased from the time-space continuum, I don't think so." Sam said, earnestly.

"Mom, I won't be erased." She said, seriously. "Not entirely anyway."

Sam face showed her anguish.

"Mom, I know this is hard. And if there was any other way..."

"I know..." Sam said, trying to keep from releasing her tears. "You're just...you're too much like your father."

Grace chuckled, though tears of her own were slipping down her cheeks. "You have to convince them to do this, Mom." Grace said, seriously. "It's the only chance you have of getting the Asgard core back to Earth. And that alone is more valuable than me."

"Nothing," Sam said, earnestly. "Is more valuable than you."

"Please, Mom." Grace pleaded.

Sam sighed before nodding. "All right. I'll do it."

--

"Teal'c." Grace said, looking at him as she swallowed. "Are you...ready?"

Teal'c tucked the small package he'd hidden on his person further into his pocket. "Indeed I am." He said, nodding.

Grace accessed the ship's computer, and turned off the time dilation field as she booted up the program to reverse time. Then, she prepared for the blast wave.
