If you haven’t seen “NCIS” season 17 episode 10, you’re going to want to stop reading right now. We’re about to reveal a spoiler that might ruin the show for you.

Fans were shocked to see “NCIS” season 17, episode 10, titled “North Pole.” In this episode, it was revealed that Sarah is Sahar, the woman who wants Ziva (Cote de Pablo) dead. She moved in next to Gibbs so that she could spy on him and get to Ziva. Sarah used Phineas to gain Gibbs’ trust. It worked, because Gibbs took Phineas under his wing and became like a father to him. He taught him how to play baseball, helped him with a science project, and took care of him while Sarah was away. Toward the end of the episode, Sarah finally catches up to Ziva and tries to kill her, but Gibbs comes to Ziva’s rescue in the nick of time.

Before Sarah’s true identity is revealed, she presents herself as a single mother who works as a waitress. Sarah said Phineas grew up with his father for the first half of his life, but recently moved back home with her. She also said there was a custody battle taking place. Now that we know who Sarah really is, we’re not sure if her story is true.
