Letty’s awareness that Lovell is Robin’s father makes it clear that others have picked up on the fact that the two are related, even if Robin hasn’t said anything. That seems to make Lovell’s disavowal of Robin as his son that much more egregious, as the fact appears to essentially be an open secret. Lovell’s lack of knowledge of Cantonese—and his apparently purposeless efforts to teach Ramy, Letty, and Victoire Mandarin—highlights Lovell’s racism, and it suggests that he doesn’t actually want to learn or teach languages that are going to lead to positive cultural exchange and understanding.
