Emily Wickersham returns as Bishop for multiple NCIS: Origins episodes

Emily Wickersham is returning as Ellie Bishop in multiple episodes of NCIS: Origins, with her first appearance set for next Tuesday’s episode at 10 p.m. on CBS. The move turns a one-off crossover into a recurring run, giving the prequel a storyline that stretches past a single hour.

October 27 on CBS

Wickersham’s NCIS: Origins debut lands on October 27 at 10 p.m., and that date is the first concrete marker for how this crossover unfolds on screen. She left NCIS in 2018 after eight seasons, which makes this return a reversal of a departure that had already ended one chapter of Bishop for the franchise.

Mark Harmon’s Gibbs appears in every episode this season, and the series is using that constant presence to bring Bishop back into a case built around him. In the prequel setup, Austin Stowell plays a younger Gibbs, which keeps the story anchored to a version of the character still carrying the fallout from the season premiere shooting.

Tony DiNozzo sets the hook

Tony DiNozzo brings Bishop back into the fold by enlisting her to help Gibbs track down the unknown assailants who shot him. The Tuesday episode also reunites Gibbs and Tony DiNozzo, tying Wickersham’s return to the franchise’s broader family rather than treating it as a standalone nostalgia beat.

That setup gives the series an operational reason to use Bishop beyond a guest drop-in: her assignment is tied to an off-the-books investigation, and Gibbs tells her to gear up in the sneak peek. The result is a return built around active casework, not a brief appearance designed only to acknowledge the past.

Bishop stays off the books

“Missed you, too.” Wickersham’s Bishop says that line in the sneak peek, and the next one makes the assignment clear: “Yeah, well, that's why he called me. My whole life is off the books.” She later adds, “I never thought I'd hear you say that again.”

Those lines match the character history already in play. Bishop left NCIS in 2018, resurfaced on NCIS last season, reunited with Torres, and disappeared again before this new crossover picked up her trail. This return leans into that pattern, but with a sharper job description and a specific case driving the reunion.

The practical takeaway for viewers is simple: this is not a single-scene callback. Bishop’s role begins on October 27 at 10 p.m. and continues across multiple episodes, which makes her reentry one of the season’s few moves that alters the story engine instead of just decorating it.
