He told TV Line: ‘Both Renee and Barrett have been on the show a long time, and they’re both very ambitious individuals who have projects that they want to do on their own — and we’ve been giving them time off to do so.
‘It seemed like a natural time to let them go off and do some other things, and give [their characters] what is a happy, hopefully, ending.’
However, the team have deliberately left the door open for either character to return in the future, and Gemmill won’t rule out the possibility.
He added: ‘There’s a little loophole in there, when Nell says she’s going to be alone in Tokyo with Eric, and she gives it “six weeks” before she’s back. So, we’ll see what happens.’
Seasons four to 12 of NCIS: Los Angeles are available on Sky in the UK.
