This really isn't the end of Will's problems.
Buffet Froid, an analogy to the act of serving yourself, but also referring to the 1979 French film with the same title makes a point to uncover Will Graham's state of mind. Unfortunately, he is left in the dark, and the act of dehumanizing him by hiding the truth becomes apparent.
Well played, Dr. Lecter.
In a session with Hannibal, Will is confronted with the problem of feeling alive or not, and he summarizes it with the word "fading". An apt description, considering how he seems to lose himself in the process of reconstructing cases to the point, where his own identity becomes a question mark.
What does it mean for Will to experience a loss of time, to experience spatial neglect as well as hallucinations and an empathy disorder?
It isn't quite simple as overcoming delusions, as Hannibal suggests. One could clearly see how
Will didn't simply reconstruct the thoughts of a killer, but immersed himself completely in it. And this problem leads to Will's own belief that there must be other reasons, neurological in nature that lead to multiple symptoms separate from his mental health.
Identity
Finding yourself and buiding a sense of stability around you is important, which is why being diagnosed properly would have helped Will's recovery. Hannibal is having none of that and proceeds to "make his own design".He interferes and actively takes Will's agency away from him, although the hints at Hannibal's own interest in Will's conclusions of each case is constantly heightened.
Notice, how the camera focused on Hannibal's reaction when Will suggested that the killer was sad and lonely and that this murder is not based on being savage.
Sanity and insanity is not clear cut. The motivations and the truth behind certain actions is much more complex, and I would argue that this is also the case with Hannibal's intentions regarding Will's diagnosis. Will has Encephalitis, an inflammation of the brain, which means that an accurate diagnosis is extremely important, because usually a patient displays flu-like symptoms or nothing at all. No treatment can lead to a bleeding in the brain and a permanent brain damage that affects all senses. Memory loss, seizures, fever, disorientation, headache and a potential autoimmune disease are just one part of Will's problems. And Hannibal knew it all along. His manipulation becomes absolute, and Will is ultimately left with the impression that all of his symptoms are cause of a mental illness rather than a physical viral infection. Hiding the truth from him means that Hannibal takes control of Will's identity construction, his search for stability and treatment. His life is now in Lecter's hands.
Parallels
Georgia wants to feel alive and she believes she does not, which is underlined by the problem of not being able to recognize faces, although she tries to. A similar approach was introduced by Hannibal in order to anchor Will to reality. The problem is a skewed perception of space caused by his viral infection, while Georgia experiences impairments in the visual system that is responsible for recognizing faces. Ultimately, Georgia cannot anchor her own body to herself. The major difference is that Will knows he's alive, while Georgia disconnects with her own body, exhibiting signs of Cotard's Syndrome, a mental disorder. Will's empathy disorder, on the other hand, correlates with his physical problems, adding to the bigger picture. However, Georgia manages to find herself with Will's active attempt to reach out and to help her, which was easily my favorite scene.Intentions
"Will is my friend." Is he or is he not? The degree of interest turning into obsession is fascinating to watch, because Hannibal gains control of himself by being fascinated with another human being. He describes Will's remarkably vivid imagination as beautiful, and Dr. Sutcliffe falls prey to Lecter's motivations because of that. And because he was rude.Hannibal swears he will "put out the fire", but my impression is that he wants to pour some more oil on it, having a fire that consumes everything in the process.
