Tulsa actor Zach Lewis has a lot on his mind these days.
First up, the Holland Hall graduate is guest-starring in Tuesday's "Patriot Acts" episode of "NCIS: Los Angeles" on CBS. He stopped long enough Friday to do an email interview with the Tulsa World.
In the episode, airing at 8 p.m. on channel 6, a former Marine is suspected of creating a chemical bomb, and the NCIS: LA team joins the FBI's domestic terrorist task force in the investigation. The episode marks the return of Operational Psychologist Nate Getz (Peter Cambor) to the show and the first appearance of a young FBI agent played by Lewis - a role that could possibly become recurring on the series.
