There's absolutely no way he's schizophrenic, I can only assume you have a "layperson's" understanding of schizophrenia because... well... it's nothing like this. It's a pretty serious and obvious mental disorder.

I do have a psychology degree although I have never worked professionally in anything psychology related... so my opinion isn't a professional one either... BUT my thinking would be more along the lines of him being towards the "mild" end of the Autistic spectrum, maybe mild Aspergers that was never diagnosed in childhood. People who go undiagnosed with mild autism in hildhood quite often learn "techniques" to cover it so it's never really noticed, however, this very unusual, intense, highly social situation seems to be butting his "masking techniques" into overdrive and making him appear strange.

Reasoning:

- He is quite intelligent

- He thinks logically...

- ...but struggles to understand when people react instinctively when it doesn't comply with his "black and white" view of it (e.g. "how can you be too nice? Nice = good!")

- He's socially awkward with things he says and social boundaries

- His mannerisms and ways of expressing himself, including his "rants", don't feel natural... as if he's "acting how he thinks someone would act in that situation".

- His emotions are the same as above, e.g. when he got "upset" on the date with Charlie, and his "love that boy" tears with the Sam / Callum therapist thing. It's not that he doesn't feel these things, just that with an ASD (Autistic Spectrum Disorder) his emotions would be naturally internalised and not show externally - it's like he's learned at some point in his life that people don't like to see someone "emotionless" and so he's using learned emotional displays to show his emotions. It's not that the emotions aren't real... just that his externalisation of them is "faked".

- He gets visibly frustrated and agitated when people misunderstand him or his intentions.



...so yeah, like I say I'm not a professional but he is quite psychologically "interesting". He's certainly not "normal", but there's really nothing wrong with that. He seems harmless, just quirky, IMO.
