She came to the Pegasus Galaxy in the hopes of fighting "major alien bad guys", in other words, the Wraith, since she thought there wasn't much to do in the Milky Way since the Ori were defeated. She often seems very determined and straight. In 2008, she and her team were investigating a planet when they came across a Wraith lab containing Michael's experiments. Teldy felt she needed assistance, and called in Lt. Colonel John Sheppard and Dr. Carson Beckett, who had first hand experience with Michael's work. She also participated in defeating the experiments. (SGA: "Whispers")
