NCIS fans were treated to a major surprise in the December 16 fall finale: Ellie Bishop is back. But the beloved former agent isn’t returning as an ally – at least not yet.
Now played once again by Emily Wickersham, Bishop appears on the opposite side of the team in a storyline filled with secrecy and tension. Katrina Law’s Jessica Knight receives her first NCIS: Elite assignment, and her target is none other than Bishop. Vance keeps the mission strictly confidential – even from Torres, Bishop’s former love interest – while Bishop secretly watches the team from afar.
Fans immediately exploded online with excitement.
“Caught me completely off guard!” one viewer wrote. Others called the twist “the best surprise in years,” with reactions ranging from joyful screams to shocked gasps. Many agreed: Bishop’s return felt long overdue after her controversial Season 18 exit.
But questions remain. Is Bishop truly a threat? Or is she deep undercover – or even being framed?
Executive producer Steven D. Binder teased that Bishop isn’t being targeted “because she’s been a good person.” He explained that fans are meeting “Bishop 2.0” – a version shaped by years of high-stakes pressure, shifting loyalties, and hard choices. When she reconnects with the team, she won’t be the same person they remember.
And that’s exactly what makes her return so compelling.
Ellie Bishop is back – changed, complicated, and full of mystery. And NCIS fans can’t wait to find out which side she’s really on.
