FYI, in my mind, this takes place after Sam, Jacob, and Ba'al work together to defeat the Replicators. And just because I can I ignore the fact that Janet is supposed to be dead by now, Sam either never got together with Pete or she ended it back when he proposed (your pick), and Jacob is still alive. Yup, that works better for me - these aren't mine, no money was made, hope it doesn't suck.
Chapter 1: Ten Weeks
Ten weeks and two days. He could tack on the fourteen hours too. He'd lost track of the minutes but, Jack O'Neill still counted the hours since Samantha Carter had vanished. She'd been off-world with SG-1. It had been a simple recon on an uninhabited planet. Daniel had requested that SG-1 go so that he could study the monuments while Sam had requested to go to take more soil samples – there had been some element or something present that she wanted to know more about. Hammond had agreed; they were on downtime anyways. Even Jack figured it would be a good idea to let the Ph. D.s play.
Everything had checked out. They'd been on the planet for days and then one morning they had woken up to find Sam gone. They'd sent word to SGC, received back-up and searched for days. There was no sign of Goa'uld technology anywhere but, that didn't mean that they hadn't used the Ancients technology. The problem was with Anubis and most of the Goa'uld defeated no one knew why she had been taken, or if it had even been the Goa'uld. Especially with no evidence. The Goa'uld weren't usually so careful with their dealings; they usually flaunted what they did.
It didn't matter though. None of it did. Because ten weeks and two days after her disappearance Major Samantha Carter was officially listed as Missing in Action.
