Well, when I answered the challenge originally, it was for Buffy/Jacob. I kind of ... didn't get that far. But that was the intention: that it would evolve that way eventually, and a certain unnecessary event from "Threads" would not happen. (No, not the Daniel one this time; the Jacob/Selmac one. *grin*)

This is kind of how I envisioned the next bit:

Once the blending's done, the SGC is going to want Buffy back. But after speaking with Carmentis, Buffy will know that's not a good option. She doesn't want to be trapped on-world without her own easy access to all the Slayers, and heck if she's going to explain why she wants right back out to the stars immediately. Only, she's going to react badly to the Tok'ra, too, because they'll be wanting to keep her close and safe and see if Carmentis has any clues to what they should do next (being their Seer).

She'll have to talk Jacob around to springing her. From there ... Lots of possibilities. One day I'll write it.
