Chad's Summary: SG-1 travel to a world where the entire population are suffering from mass amnesia. They meet a woman named Ke'ra (Megan Leitch) who take SG-1 to a library. SG-1 discover that Linea (from "Prisoners") caused the Vorlix--the chemical agent which caused the amnesia. Dr. Fraiser begins tests on the people to find out if the Vorlix can be reversed. Meanwhile, Daniel begins to have feelings for Ke'ra. Orner (Jason Gray--Stanford) and Layale (Marya Delver) go to Earth with SG-1 and Dr. Fraiser for more in depth medical tests such as a Magnetic Resonance Imaging (MRI) test. Despite the recent loss of Sha're, Daniel has a romantic relationship with Ke'ra. Dargo, a chemical pesticide which has a life extending effect, caused the Vorlix. Dargo also has a disturbing side effect which causes sterility. Ironically, using Dargo to extend life may also put an end to the natural reproduction of the planet's population. SG-1 also discover that Ke'ra is, in fact, Linea. Daniel believes that Ke'ra is a different person than Linea. Ke'ra, Carter, and Dr. Fraiser come up with a cure for the Vorlix which Ke'ra can not take. After some time, Ke'ra takes the drug and regains her memory. Jackson realizes that Ke'ra remembers being Linea. Linea plans to kill herself, however, Jackson convinces her to live. Linea is infected with the Vorlix again and returns to the planet. Except for Ke'ra, all people infected with the Vorlix are cured.
