Young has a strong command presence, but must continually deal with civilian scientists the likes of Dr. Nicholas Rush, who pay him lip service but subvert his orders when it is in their own interests. He has clashed with Rush several times, even beating him unconscious and leaving him behind on an alien planet after Rush framed him for murder -- a decision he came to deeply regret. Young seems to recognize that he's not the right man for this difficult command, and despite his best efforts has made poor command decisions in the attempt to keep his people safe.
Everett was originally assigned to command the Icarus Base, a post he accepted against his wife Emily's wishes. He held that post for approximately two years, while Rush and a team of experts pursued the Ninth Chevron Project there.
When Icarus came under surprise attack from the Lucian Alliance, Young ordered an evacuation back to Earth. But Rush countermanded Young's instructions and instead dialed the Stargate's nine-chevron address. With the computers damaged, Young had no choice but to evacuate the team to the other side, where they found themselves on Destiny with little food, water, or air, and no way home.
Everett had an extramarital affair with Lt. Tamara Johansen, an officer under his command at Icarus. He broke it off and told his wife about it, but after they arrived on Destiny the two learned that she had become pregnant. The child, Carmen, was lost when T.J. was accidentally shot during an incursion onto the ship by Lucian Alliance forces -- though she believed for a time that a race of highly advanced aliens had intervened and saved the child's life.
Young has used the ship's long-range communication stones to visit his estranged wife on multiple occasions, but their separation soon became final. With the revelation of Destiny's long-term mission, Colonel Young dedicated himself to its pursuit.
