Sarek has a Bendii-like illness that robs him of his emotional control but not his coherence or memory. Is he becoming human?
By no means. He is a Vulcan, through and through. Even with his control waning, he is still a thousand times more patient and logical and calm than we could ever hope to be. From time to time, he finds himself overwhelmed by the burden of the emotions, as when Saavik recounted Hellguard to him, or when he found out that Peter respected him more than he did his own legal father, Sam Kirk. No, Sarek is not and never will be human. But as a Vulcan, we may see new sides of him, and like what we see.
