From The Stargate Omnipedia
First Lieutenant in the U.S. Air Force and a member of Destiny'
Though relatively inexperienced at the concepts of the Stargate or interstellar travel, Scott is a capable leader with a strong sense of the chain of command. He is head-strong but willing to rely on the support of his fellow officers and friends. The survival of the Destiny crew is his first priority.
Still, he struggles with numerous demons. Scott lost his parents to a car wreck at the age of four. A Catholic priest raised him for the next twelve years until he died of his alcoholism. At a young age Scott considered joining the priesthood himself, but he began to question those plans when he impregnated a 16 year old woman. He believed for years that she had aborted the baby, and discovered (after being trapped on Destiny) that she had the child and is now raising his son.
Icarus Base was Scott's first S.G.C. assignment after training. While there, he became consummately involved with his subordinate, 2nd. Lt. Vanessa James, against regulation.
When Icarus Base came under attack, Scott was the first officer to board the Destiny. The chaos that ensued included the casualty of his superior officer, Col. Everett Young, who was badly injured. Young placed Scott in charge, and he immediately went to work to restore order and establish a line of authority. He ordered the Destiny searched and worked with Dr. Rush to deal with the problems that began to afflict the crew.
Despite his rogue nature, Scott still wears a cross around his neck. He counts Ronald Greer as one of his most trusted friends. He has developed an intimate relationship with Chloe Armstrong -- perhaps one of the first serious, long-term relationships of his life.
