Lynn does have quite a few, but - hard to tell them with no language to speak.

She asks some questions about words by pointing and saying, "Name?" and manages to cobble together a slightly larger pathetically small vocabulary before they get to New York.

It's a long drive, but eventually, they arrive in New York.

Even without the language, Lynn knows the way. She gives slightly clumsy directions, with the language barrier, but they manage. Eventually, Lynn points at an apartment complex, and says, "Son."
