This idea came to me as I was reading some comments about Daniel/Sha're's
relation interaction during "Children of the Gods" and "Forever in a Day" and started remembering a meta and some prompts on the
SD-thon forum that I read awhile back.
Basically the idea could be very shortly described in a prompt-fashion as:
Season 3, Forever in a Day - What if it had been Sam who had followed Amaunet/Sha're into the tent and ultimately received Sha're's message?Some stuff that writers should have in mind for the story (some sort of guidelines, if you will):
- Two different hallucinations/dreams: the first one where Sha're was killed by Teal'c and Daniel is dealing with her death; and the second where Sha're was rescued by the Tok'ra, while Daniel was in the infirmary, and she starts to adapt to life on Earth.
- Sha're asking Sam to help Daniel forgive Teal'c and look for her son.
- Sha're hinting that she is okay with Sam having feelings for Daniel and telling her to not be afraid to act on them.
- If you wish you can simply leave it at Sam/Daniel unrequited or UST - that way it will leave room for a sequel

Have in mind that Daniel was actually present during all the events of the hallucination that Sha're gave him, so the same should happen with Sam.
PS: Actually, looking back at what I just wrote I'm not sure if this is good enough to work as a story on its own. Nevertheless, I'm pressing the submit button.
