A little over a year after their divorce, Sara was approached by a man she thought was Jack, but who was, in fact, an alien duplicate. The alien told her that he/it was looking for Charlie and that he/it had to get back to the Stargate, which she had never heard of. When it began breaking down due to the Earth's electromagnetic field being stronger than P3X-562's, she took it to the hospital. When Sara saw the real Jack O'Neill, she was very surprised. (SG1: "Cold Lazarus")
In the Stargate film, her name was Sarah O'Neil, and she had not yet divorced her husband.
