Someone brushes their teeth and spits into a trash can, but it is not vomit. Later in the movie, Mark Baum says he feels very sick, but he does not throw up. I did not see any vomit.
Not specifically but the main character is autistic and people do not understand him and become uncomfortable because of his behaviour. No straight insults, just ignorance.
Since there's no section for racism? I guess I'll put the anti-immigrant comments from one character and "his names Yang, he won a math competition in China, and he cant speak English" comments from another character here. The movie doesn't condone it or seem to approve but it does happen
