In the storyline, Hetty was frequently sent on dangerous overseas missions, often leaving cryptic messages for her team. However, these plotlines were designed to gradually phase out the character as Hunt stepped back from acting. Even though there were hints about her possible return, it ultimately never happened before NCIS: Los Angeles concluded.
Now, with the show officially over, fans have come to accept that Hetty’s disappearance was a mix of both storytelling choices and real-world circumstances. While her absence left a noticeable void, her legacy as the team’s fearless leader remains one of the most iconic parts of the NCIS franchise.
