How does Gordie respond to True Son?

Gordie is delighted at the sight of the young Indian (True Son). With some effort they get him upstairs to his mother's bedroom. She kisses him and calls him by his old name of John, but the boy does not seem to understand her. He refuses to speak his Indian name and surprises everyone by saying in English that his name is True Son and that his mother and father gave it to him. Mrs. Butler gives up and gives him clothes to change into. Gordie asks for his Indian clothes, saying he wants to be an Indian. This, along with the fact that the little boy has addressed him as True Son, makes him begin to like his younger white brother.
