Given Bob’s earlier insistence that home wasn’t important, it’s perhaps not surprising that he frames living with Julia’s family as him doing them a favor. It allows Bob to feel like he’s the one in control—even though, as an animal, he depends on his human family to feed and care for him. It’s also significant that George makes a note of how good Ivan looks—this implies that Ivan was in rough shape when he lived at the mall. Exchanging this long look with Julia, meanwhile, suggests that they don’t need language to communicate—they love each other and have bonded over being artists, and that’s all they need.
