However, she did take to Instagram to reveal Nell currently has a lot going through her mind.
Posting before it aired, she wrote: “Tonight a wistful Nell comes to your small screen.
“Tune in for an episode to remember directed by the inimitable #EricPot my fave.”
The promo for the next episode, which airs on Sunday, April 12 does not have Nell in it so it seems viewers will have to keep tuning in to find out more about her future on the show.
NCIS Los Angeles airs weekly on Sundays on CBS.
