Spoilers ahead for the May 18 episode of NCIS Season 18, called “Blown Away,” and the promo for the May 25 finale, called “Rule 91.”
After spending several episodes of the season subtly calling attention to changes in Emily Wickersham’s Ellie Bishop, the promo for next week’s finale combined with the episode description suggest that Bishop could be on her way out.
NCIS debuted newcomer Katrina Law’s Jessica Knight in “Blown Away” to set up the possible future of the series following its renewal, but it’s the fate of a longtime star that fans should probably be concerned about heading into the Season 18 finale.
