As NCIS Season 23 builds momentum, “Deal with the Devil” promises to deliver both procedural intensity and personal fallout. Episode 19 revisits Alden Parker’s complicated family history with the return of Nancy Travis as Harriet Parker — a reunion that’s anything but warm.
Despite earlier interactions suggesting a possible reconciliation, the episode makes it clear that the siblings remain estranged. That tension bubbles to the surface just as Parker faces a difficult case involving a secret immunity deal that could let a suspect escape justice.
The timing couldn’t be worse. With his professional instincts pushing him forward and his personal history pulling him back, Parker is forced to confront both at once. It’s a dynamic that adds depth to the case and raises the emotional stakes.
Following recent guest appearances by LL Cool J and Emily Wickersham, Travis’s return continues a standout season filled with familiar faces and layered storytelling.
