Season 12 of "NCIS" is coming to a close, which means the show's ardent viewers can expect two action-packed episodes and the death of a main character in the finale. The show promises to provide sensational episodes, as the NCIS team investigates a terrorist organization having its roots in Egypt and Iraq.

In the upcoming episode 23 suitably named "The Lost Boys", an NCIS cyber-case turns into a united global effort, reports SpoilersGuide. Evidence from the case confirms that an international terrorist group is recruiting children through the Internet and this group, named The Calling, has also been purchasing multiple S-bombs from the black market. These disenfranchised teenagers are the center of the upcoming episode. The penultimate episode also sets stage for the finale that will essentially revolve around the NCIS team taking down the international terrorist organization.

Additionally, fans will be happy to see a couple of familiar faces back on the team. TVLine reports that Mimi Rogers debuts as a CIA agent and McGee and Dorneget will be sent on an adventure to Cairo. Showrunner Gary Glasberg also teased an emotional finale, which features the death of a main character. A significant loss is set to drive fans to the finale, so audiences should keep a tissue box handy for the last two episodes of season 12 of "NCIS".

Meanwhile, there are speculations that Tony Dinozzo could be the next casualty on the show, as TVLine reports that the actor playing his role, Michael Weatherly, is set to appear in an "NCIS: LA" episode. This is the first time that "NCIS" and "NCIS: LA" are doing a crossover. However, the latest news is that he will appear in the spin-off's next season (season seven). Either the actor's character dies in the finale of "NCIS", or he lives on and appears in the crossover episode. The report also notes that the "NCIS: LA" team completed the shooting for the crossover before season seven's filming schedule. Was Michael Weatherly unavailable for work during the shooting schedule?

Glasberg also teased about the season finale to TVGuide, saying, "It's a pretty surprising ending and a pretty disturbing ending...that I don't think anybody's going to see coming." "NCIS" airs on Tuesdays 8 p.m. ET on CBS.
