Summary: Something goes wrong during the evacuation of Atlantis, stranding members of the Atlantis expedition and SG1 on a very strange world. (Rodney McKay/John Sheppard throughout; later includes Radek Zelenka/Daniel Jackson, Elizabeth Weir/Stephen Caldwell, Teyla Emmagan/Ronon Dex, Carson Beckett/Major Lorne, Sam Carter/Teal'c, Dr. Kavanagh/Lindsey Novak, and Cameron Mitchell/Carolyn Lam)
Summary: Rodney McKay can't lie. He really can't. He's lost entire fortunes playing poker because he can't keep from giving himself away.
So when he lies and tells his sister that he and John Sheppard are involved--he and the very straight John Sheppard--you know things are going to go terribly, horribly wrong.
