"Sg-1 returned from a planet where they had encountered an elderly man named Ma'chello, an inventor who had spent his life devising technology to fight the Goa'uld. He believed he was owed a new life in return, and used his technology to trade bodies with Dr. Jackson. While Jackson lay dying in Ma'chello's body, SGC personnel apprehended the real Ma'chello in Colorado Springs, Dr. Jackson convinced him to return to his own body, telling Ma'chello that if he took another person's body against his will, he was no different than the Goa'uld whom he had spent a lifetime fighting." - General George Hammond
