About Jack Sloane on NCIS?

Agent Jacqueline "Jack" Sloane was introduced in season 15 when Director Vance sent her from the Southwest Field Office in San Diego. She wasn't merely a field agent—Jack was also an operational psychologist and a retired Army lieutenant. Her profiling skills and knowledge of human behavior were assets to Gibbs' team, especially after Dr. Mallard stepped back from active participation.

Jack's function went beyond case-solving. She was a friend and support system to her teammates, always ready to listen to their problems. One of the consistent aspects of her personality was her lollipop jar—each team member's preferred color of candy would subtly play a part in her psychological profiling.

Moreover, fans often speculated about her connection with Gibbs. Although nothing was ever officially revealed, their strong bond and chemistry indicated an emotional relationship that was more than that of friends.

Her last episode, season 18, episode 8: True Believer, was an emotional goodbye. When a group of children was kidnapped by the Taliban in Afghanistan, Sloane's past caught up with her and forced her to act.

Gibbs went on the mission with her, and after a successful rescue of the children, Jack made a decision that changed his life forever—to remain in Afghanistan and commit herself to making a difference. Before Gibbs' return home alone, the two had a poignant goodbye, which they sealed with an emotional kiss.
