When Maverick is shocked that the entire office seems to be Black, it implies that he expects medical professionals to be white. This is perhaps a consequence of growing up in Garden Heights, where Black people like Maverick and his family are largely disenfranchised. This doctor’s visit, in other words, is introducing Maverick to the idea that Black people are just as capable of becoming successful professionals as people of other races are. Lisa demonstrates her maturity by coming prepared with so many questions, while Maverick’s question about whether the baby will “see stuff” if he and Lisa have sex is comparatively immature. But still, Maverick doesn’t want to look young or unintelligent in front of the doctor. Given how little he knows about pregnancy, asking when they can find out the baby’s sex is all he can come up with.
