I wondered if Cliff had AS traits too, but I think Lilith seems the most AS for some reason.
She's socially awkward, she gets meltdowns, she have a very monotone voice, she insist on having her hair the same way, she isn't very good with emotions, she sais to Norm she never was good at making friends and never had many friends, she is obsessed with her own work and is often seen "in her own world" reading or writing notes while the other people in the bar socialise.
I often felt kind of sorry for Lilith, cause I thought the other people in the bar wasn't nice to her.
Her official personality profile doesn't say very much about her:
-A remarkably unemotional and restrained woman (her hair usually tightly pulled back in a severe bun), she has exceptionally pale skin, a monotonous voice, and dresses almost exclusively in drab, conservative clothing. She tends to express herself in long-winded, exacting, technical sentences suffused with psychological or medical jargon. Upon greeting the expecting Daphne and Niles, she congratulates them on "the successful co-mingling of their genetic material."-
