Right before, and right after Jenny died people berkata she had a terminal illness. Did they ever mention what it was? I missed it.

This was all i could find in the ncis Wiki, so i think its all we'll ever know!


In several episodes during season five, before her death in the episode "Judgement hari (Part 1)", her failing health becomes a plot issue as for example when Ducky is shown to be ordering a test on a blood sample to Abby, telling her that it is from a John Doe. However, when Abby talks to Jimmy Palmer, he says that they have no John Does. Gibbs deduces, correctly, that the only person Ducky would act this way for would be the Director, at the end of the episode "Stakeout". In the selanjutnya episode "Dog Tags", Gibbs pertanyaan Jenny about her illness and she lies to him, saying she's fine.

Mike Franks also discovers her illness oleh going through her tas, dompet and finding her medication. In the episode "Judgement hari (Part 1)", Franks and Jenny are talking in an abandoned kantin, diner in the California desert and she indicates that she is dying and reveals that she regrets her decision to leave Gibbs in Paris and that she's still in cinta with him.
