What idiom did Peter speak?

Heiii luvs. I usually talk with Peter Pan like at 10:30 pm. Sometimes he give me signs. I talk to him in my native language wich is not english (probably that explains my gramaticalmistakes) and i was thinking about this "What if he just understand his name 'cause is similiar with the pronunciation in english but he don't understand the things i say to him?

te guys think Peter understand the other languages?
