The episode, which aired on Tuesday, followed Special Agent Timothy McGee (Sean Murray) as he introduced his newly discovered adult son, Mateo (Patrick Keleher), to the NCIS team.

Mateo’s Mysterious Visit to NCIS Headquarters

McGee, who recently learned about Mateo’s existence, invited him to tour the agency’s headquarters. However, Mateo’s conflicting stories to McGee and fellow agent Nick Torres (Wilmer Valderrama) raised suspicions. The tension escalated into a standoff in a dark alley, where Mateo warned Torres that stopping could put him in danger. The episode ended abruptly, with a gunshot heard in the distance—leaving fans to speculate about who was shot and what happens next.

Sean Murray Reacts to the Cliffhanger

"I see at least three or four awesome ways this can go," Murray told TheWrap. "What does it do to Mateo? What does it do to Torres and McGee’s relationship? A lot of stuff’s at stake here."

Murray expressed excitement about the finale, calling it a creative high for the long-running CBS series. "The fact that I’ve been here for 23 years and I’m super excited about this finale. I think it means we’re doing something right," he added.

NCIS Hits Milestone with 500th Episode
