In other threads you mention that you’re a healthcare professional so surely you can see that Harvey does not exhibit any of the physical signs of PW? He hasn’t got small hands and feet, he isn’t of small stature, he wasn’t a floppy baby and he hasn’t got a high enough IQ to qualify either. PW people have low to normal metal ability and can have normal lives. Harvey is a lot worse than that. It’s been suggested many, many times that his difficulties are the result of his mother’s heavy drinking and drugging while she was pregnant.
