Tony's woman (who he got involved with because she was the daughter of a drug dealer/arm's trader) left the scene and felt betrayed a few seasons back. Do you all think it likely she'll be back ever?
Sadly, I too doubt that she will be back. Tony lied to her and told her that he never had any real feelings for her so that she could move on.
Her father was killed by his handler at the CIA (or, at least, that's what Kort led the FBI to believe.) Shot in the head and fed to the fishes. The last scene between Jenny and Gibbs could lead one to conclude that Jenny was involved in that.
The handler took credit, but I am fairly convinced that it was Jenny that killed him. I am still annoyed that they never revealed how someone managed to put her father's finger prints on the glass in her home or why the dying friend of her father was so convinced he had just seen her father.
