Julian is overwhelmed/excited and without realizing it he starts rocking/bouncing/flapping his hands and when he realizes he’s doing it he gets self conscious. He remembers his parents grabbing him and shouting at him to sit still and he feels bad that he couldn’t control it.
But his friends don’t look mad or bothered at all. Garak’s giving him the fondest smile, Miles just rolls his eyes and smirks because that’s just another thing lovable ridiculous Julian does, Dax tells him it reminds her of one of her previous host’s kids.
I feel like when Julian was taken to get “fixed”, they just enhanced him. They didn’t remove the autism. They just made him “better”. (You can try and tell me he’s not autistic but not only does he show traits of being autistic, but it’s pretty heavily implied in a few episodes.)
Ok but consider:
