NCIS leans into both tension and history with Season 23, Episode 19, “Deal with the Devil.” The episode brings back Nancy Travis as Harriet Parker, but instead of closure, viewers can expect confrontation.
Despite earlier appearances suggesting the possibility of reconciliation, Harriet is once again described as estranged from her brother, Alden Parker. That unresolved dynamic becomes central as Parker tackles a case involving a secret immunity deal — one that could let a suspect walk free.
Determined to pursue justice, Parker finds himself pulled in two directions: the demands of the case and the emotional weight of his family history. Harriet’s unexpected arrival ensures that neither can be ignored.
Following a season packed with notable guest stars, Travis’s return adds another layer of complexity. Written by Andrew Bartels and directed by Diana Valentine, the episode promises a compelling mix of legal stakes and personal reckoning.
