Red Part 2 (or "Red-2") is the 19th episode of NCIS: Los Angeles Season 4 as well as the 91st episode of the entire NCIS: Los Angeles series.
OSP and the NCIS: Red Team head to El Centro, California to stop a terrorist hitman, only to discover that all is not what it seems when they find their main suspect while everyone suspects a possible romance is brewing between Callen and the Red Team leader, Paris Summerskill.
- LL Cool J (Sam Hanna) reads the "Previously on NCIS: Los Angeles" title card.
- On May 15 2013, two months after this episode had first aired, CBS confirmed that NCIS: Red was officially passed on and would not be moving forward due to both episodes being poorly received. As such, this episode and Red Part 1 (episode) are the only two episodes to feature the NCIS: Red Team with the exception of Dave Flynn who would later reappear in an episode of NCIS: Los Angeles Season 8.
