When Carter joins the Atlantis expedition as commanding officer, a framed photo of O'Neill is seen on top of a box of her personal effects. A scene was cut from the "Stargate Atlantis" season 4 episode "Trio" in which Carter and Dr. Jennifer Keller discuss their love lives. When asked by Keller if she's seeing anyone, Carter initially avoids the question before admitting that "it's complicated" and that the man in question is in Washington D.C. but is going to retire soon.
