what is the conductors attitude towards antonia?

The conductor notes that the immigrant car is separate from the others. He says that they can hardly speak English intimating that they are not intelligent. He, however, thinks Antonia is different. She is both physically attractive and bright,

'They can't any of them speak English, except one little girl, and all she can say is "We go Black Hawk, Nebraska." She's not much older than you, twelve or thirteen, maybe, and she's as bright as a new dollar. Don't you want to go ahead and see her, Jimmy? She's got the pretty brown eyes, too!'
