Since
The Bone Sparrow is told from Subhi’s perspective (and since Subhi is a young child who has only ever known life in the refugee camp), it’s worth keeping in mind that Maá and Queeny originally came to Australia to seek asylum—that is, to immigrate to Australia and make a life for themselves there. As Maá stops speaking Rohingya and encourages Subhi to speak English, she tries to prepare him for a life outside the camp. However, Subhi doesn’t want to lose the connection to his heritage; he seems upset, for instance, that he doesn’t speak Rohingya.
