enjolras is fucking autistic canonically and here’s why:
-he hyperfocuses. he literally goes one-track-mind when it comes to the revolution he’s working on. neurotypical people rarely if ever go that hard and that long on anything.
-he does not notice, like, at all, that grantaire is in love with him until like, the very end of his plot arc. reading emotions (like romantic interest/recognizing flirting especially) is something that’s often hard for autistic folks like me
-he doesn’t do or ‘get’ flighty romance. and while there’s plenty of non-autistic people who don’t do dates and hookups and such, being uninterested in playing around with finding partners is something that me and many other autistic people experience.
-he’s quiet and relatively focused except for when it’s a topic he’s passionate about or something he feels very strongly about. these ‘outbursts’ of strong feeling that almost feels like it comes from a different mental area than normal conversation is also a trademark autistic trait
-extremely, extremely close relationships with his circle of friends. his very deep and somewhat codependent relationship with the triumvirate is a good example of this. he doesn’t make acquaintances very much, he pretty much either doesn’t really interact with someone on a personal level or has a very close friendship with them
-strong, uncontrollable emotional swells. we touched on that earlier, but things like his sudden impulse to execute le cabuc and the artillery sergeant despite it going against his ideals for how the world should be, coupled with combeferre attempting to talk him out of it/calm him down with logic, something he’d usually listen to but in this moment ignores, as well as how he almost immediately regrets it after he does it is a very strong example of the autistic trait of losing control of emotional impulse. this happens to me a lot, and no logic can talk me out of doing whatever stupid/wrong thing it is. and I almost always regret it later.
-on this vein, occasional outbursts of frustration even towards his friends, like how he snaps at grantaire. having trouble ‘reading the temperature’ of a situation or de-escalating conflict is also an autistic trait. just… not being able to take it after a certain point and snapping.
there are probably more examples that my adhd brain is too lazy to find right now, but these are just a few off the top of my head.
