Possibly he has a form of Autism.
I confess a personal stake in this one, since my son - and possibly me - has autism. Master Therapy is extremely bright, outgoing and confident, which is the opposite of the popular view of autism. He's too young for it to be known if he has Asperger's but it's been suggested as something that merits further investigation later.
Sam Stanley fitted more into the popular view as the geeky facts and figures obsessive, but Coop has many traits, too. He's very confident and friendly, often over-friendly, has little or no sense of danger or consequences, is a stickler for detail, loves to plan, organize and list stuff, and has a very precise and idiosyncratic way of speaking.
If Coop is at the High Functioning end of the spectrum, it'd make more sense that he does really, really daft things that get him into all kinds of trouble.
No idea if my idea is right, or even if the intent to make the character have Autism but the similarities are very clear. One of the doctors involved in my son's assessment said, "Everyone has traits but there's a threshold; we play a game of 'Spot the person who isn't'".
It came to me after re watching FWWM a couple of weeks back. I thought "Well yeah, old Sam, he's the comic book version but... hold on a minute, what about Cooper?" Then, RL intervened as it often does and I forgot until about half an hour ago.
That's actually really good .. and I can totally see it .. my sister has Autism and I work with a dr who has Aspergers..
