During the final episodes of NCIS season 16, we see Gibbs (Mark Harmon) exhibiting some strange behavior. He’s talking to the ghost of his dead ex-wife, Diane, being short with his team, and acting quite weird. What’s going on with Gibbs? Here’s why fans think Agent Gibbs has a brain tumor.

Some think Gibbs is having a mental health crisis

One of the first thoughts fans had is that Gibbs is having some sort of mental health crisis. It appears Gibbs is starting to buckle under the pressure at work and in his personal life. His personal and professional worlds collided recently when he was treated as a suspect in his ex-fianceé’s murder after his blood was found on her uniform (season 16, episode 20, “Hail & Farewell”). Gibbs is also under a lot of stress because he still carries guilt from the time he killed Pedro Hernandez, the man who murdered his wife and daughter.

Although fans conclude Gibbs is having a mental health breakdown, one NCIS insider said this isn’t the case. In an interview with TV Line, co-showrunner Steven Binder says Agent Gibbs doesn’t entirely break down. Rather, he simply has difficulty making decisions. Binder says he doesn’t think Gibbs is even capable of having a breakdown. “I don’t want to use the word ‘breakdown,’ because it’s Gibbs and I don’t know that this man is capable of breaking down, but it presages a sort of inability for him to function properly,” said Binder.

NCIS viewers think Gibbs has a brain tumor because of the strange visions he has been having. Seeing your deceased spouse isn’t exactly normal, so fans conclude he might be hallucinating because of a tumor. Fans are concerned because Gibbs saw Ziva right after speaking with the ghost of Diane.

Since Ziva is supposed to be dead, viewers suspect he’s hallucinating. “I’m worried. Is that actually Ziva? Or does Gibbs need a head scan for a tumor? Hallucinations are a very bad thing. This isn’t the first time he’s hallucinated either,” said the fan on Reddit. Another fan added that Gibbs has experienced a lot of tragedy and he has PTSD, so she’s not surprised he’s having some issues with reality. “Considering his bouts with PTSD and unreal amount of tragedy in his life, I’d be far more worried if he didn’t have these hallucinations than if he never did,” he wrote.

Fans think Ziva’s warning is that Gibbs is in danger because he has a brain tumor

During the NCIS season 16 finale, Ziva warns Gibbs that he is in danger. It’s not clear what that danger is, but fans believe it could be a brain tumor. “If Ziva is a hallucination, Gibbs is in danger because he has a brain tumor. Next season ends up with Gibbs dying,” said one viewer.

We certainly hope Gibbs doesn’t have a brain tumor. But what if the fans are right?
