“NCIS” Season 13, Episode 22 (“Homefront”) aired May 3 on CBS without an appearance by Michael Weatherly’s Tony DiNozzo. FLOTUS Michelle Obama makes a special appearance, instead. Meanwhile, it has been somewhat confirmed that Cote de Pablo’s Ziva David is not returning for Weatherly’s departure in the upcoming season finale.

Spoiler alert: This update contains “NCIS” Season 13 spoilers for those who have not watched this week’s new episode.

NCIS Director Leon Vance (Rocky Carroll) and Tobias Fornell (Joe Spano) continue their mission to hunt down British spy Jacob Scott (Vince Nappo), who murdered former NCIS director and Homeland Security chief Tom Morrow (Alan Dale). The two bosses work with crumbs from DiNozzo, who stays off-camera in the entire episode.

The hunt for Scott continues even as Fornell’s life hangs in the balance by the end of “NCIS” Season 13, Episode 22. This Scott arc is going to connect directly to Weatherly’s NCIS exit in the finale.
