Kerry Johnson of the CIA was assigned to head up the investigation into the Goa'uld still at large after the incident in which Goa'uld symbiotes had infiltrated members of the Trust, bringing the US and Russia to the brink of war. Her assignment brought her to the SGC where she worked closely with O'Neill, and the two developed a mutual attraction that led to a brief relationship. Kerry gently ended the relationship, recognizing in an encounter with O'Neill and Carter that O'Neill had issues to be dealt with, and she urged him to retire if regulations were keeping him from what he wanted. Their professional relationship was unaffected, and Kerry continued to cooperate with the SGC in the ongoing investigation into the Trust.
