What happened at the end of the attempt in Chapter 3?

As Enrique enters the state of Oaxaca, he disembarks the train to recoup. It is crucial to blend in to the Mexican background so as to avoid deportation. He removes his dirty yellow shirt and replaces it with a white one. He washes his arms in the stream and spends what little money he has on a haircut so he will not stick out. Most Mexicans have straight dark hair, while Central Americans tend to have curlier hair. To further blend in, Enrique must also alter his speech and word choice. For instance, agua means water in Mexico, but means soda in Honduras. Also, he must remember that Mexican weigh items in kilograms instead of pounds.
