NCIS: Origins Season Finale Explores Gibbs' Decisions, Relationships

The penultimate episode of NCIS: Origins reveals a major betrayal that deeply impacts Gibbs, explaining why he became emotionally closed off in the flagship series; his veteran support group leader, Luke Fletcher, is exposed as the serial killer Sandman, leaving Gibbs feeling used and harmed. The season finale will focus on Gibbs' relationship with colleague Lala Dominguez, whose loyalty comes into question as the investigation into the murder of Pedro Hernandez resurfaces. Ambitious Military Police Investigator Lara Macy enters the scene, determined to solve the Hernandez case in hopes of advancing her own career, potentially putting additional pressure on Gibbs and Lala. The show explores Gibbs' formative years in NIS, particularly his connection to Lala, a figure he’s previously kept secret, and how these relationships shaped his future. Meanwhile, the flagship NCIS series builds anticipation for its own season finale, with McGee’s career at risk as he investigates the deputy director for corruption, while Torres and Knight face unexpected news.
