Contrary to expectations, their first mission was not to defend Earth, but to explore a strange signal that turned out to be a Hazkan. Since Commander Taylor was known for doing everything by the book, it was impossible for her to act spontaneously or creatively in such an unpredictable situation. So Carter, Leena, Seth, and Nikki took over and made it possible for them to escape.
Even during the space battle above Earth, it became clear that Taylor had little support from the crew, as the others planned the action almost without her help. After the Athens crash, she was caught, interrogated and killed by Lorgan hunters.
