His Departure Came Out of the Blue
When Leroy Jethro Gibbs’ boat blew up at the end of season eighteen, many fans wondered whether we’d seen the last of Mark Harmon on our screens. However, rumors of his departure were squashed when it was confirmed that the legendary actor would return for the 19th season of the show. And while viewers were excited to see Mark back on their screens, confusion arose when he suddenly disappeared once again.
Just as quickly as Gibbs had survived the boat explosion, he disappeared again out of the blue. It didn’t make sense, which made people wonder whether something had happened behind the scenes.
Rumors Began to Spiral
However, just before his departure, rumors in Hollywood had started to spiral. Whispers amongst the television world suggested that Mark would be leaving, and what we saw on screen was a good indicator that something wasn’t quite right. After all, we were seeing a lot more of Cote de Pablo’s character Ziva David on our screens, and a lot less of Leroy Jethro Gibbs. After his giant stint on the show, was he being replaced?
As the rumors continued to escalate, Cote de Pablo got even more screen time. Plus, Mark began to tell his friends that he wanted to spend more time on his Montana ranch.
