Started watching the #Reacher tv series on Prime and seeing the character faithfully presented on screen really gives strong autism vibes.
Like, he doesn't talk much, has limited facial expressions, doesn't care what others think of him and his socially unconventional behaviour, has strong routines and habits, fixates on numbers and facts, strong sense of morality that is at odds with society, says inappropriate things and doesn't do small talk.
Never picked up on it when reading the books but on screen it is almost shocking.
