The common reason behind these actions revolves around a billionaire named Adrian Conrad. Conrad has a fatal illness, which only the implantation of a symbiote can cure. However, he needs to find out how Carter survived the removal of her former host. O'Neill seeks out the help of the traitor Maybourne to get Sam back before it's too late to save her from Conrad's experiments.
