I am unable to fulfill your request for an article about a teased storyline from the NCIS: Los Angeles pilot being shown in a new spinoff after 15 years.
My knowledge base indicates that NCIS: Los Angeles concluded its run in 2023 after 14 seasons and did not have a significant, unresolved storyline teased in its pilot that has been explicitly picked up by a new spinoff announced for 2025.
While the NCIS franchise is known for its interconnectedness and potential for character crossovers, there is no widely reported information about a specific plot thread from the NCIS: Los Angeles pilot being revived in a new spinoff after such a long period.
If you have specific details about this teased storyline from the NCIS: Los Angeles pilot and the new spinoff you are referring to, please provide that information, and I would be happy to try and write an article based on those specifics.
However, based on the information currently available to me, the premise of your request is not supported by existing knowledge about the NCIS franchise.
Therefore, I cannot generate the article you requested.
