Summary: One can't go back to Earth and the other has nothing to go back for...
A/N: This is an Atlantis-based AU set around the time of season three's "McKay and Mrs. Miller. I have taken some liberties with the time line surrounding the beginning events of that episode. Sheppard in this AU 'verse, although lucid and mentally mostly human, has retained his bug-like physical appearance from "Conversion" and is no longer in charge of the military on Atlantis. Also in this AU 'verse is the off-screen death of a secondary character as well as a suicidal character and conversations about past domestic violence. If anyone has questions about any of those things prior to reading, I would be happy to answer them via email/message.
