With the NCIS: Origins Season 1 finale almost here, fans will finally find out how and why Leroy Jethro Gibbs (Austin Stowell/Mark Harmon) becomes who he is in the future, which, of course, involves Agent Lala Dominguez (Mariel Molino). Titled “Cecilia,” after Molino’s character, the episode is expected to air on CBS on Monday, April 28, and will see Gibbs face a reckoning when the murder of Pedro Hernandez (the drug dealer he secretly assassinated for murdering his family) is unearthed. At the same time, when the agent needs his team most, the loyalty of one is brought into question.
