so most of the fandom seems to be in agreement that Jules Bashir had a nonverbal and very high-support variety of autism. Now everyone knows that there’s no way to remove autism from someone–the autism and the person are intertwined. How then did Julian go from nonverbal and high-support to very verbal and low-support?
Well, two of the most significant effects of gene enhancement are perfect reflexes–meaning perfect environmental perception– and perfect memory. Julian came out of enhancement no longer able to filter stimuli. Faced with an unending torrent of information, he had to either swim or drown. He doesn’t zone out or go into stim fugues anymore because those techniques no longer work.
The gene treatment removed Julian’s capacity for positive dissociation.
