your latin-speaking tony made me think: well, tony's a genius, even as a child, and every isolated 'different' child just wants friends, right? and statistically, only a small percentage of the world speaks english, even smaller back then. so i can definitely see him trying to learn every language he can get his hands on, because obviously there's a lot more people out there then english-only speaking brats that bully him for his smarts, and meets lots of international friends!
Maria didn’t intend for all of Tony’s friends to be foreign students sent to his boarding school by equally wealthy parents but they all get along and whoever doesn’t speak a shared language, Tony happily plays interpreter for, so she’s proud of the outcome. Even if one of the boys asks why she doesn’t wear a headscarf and she explains she’s catholic and he misunderstands “Oh. Yes. I also like cats.”
