Summarize the section titled, The Flood.

The short section entitled "The Flood" is about the recent rise in unaccompanied minors immigrating to the United States alone. In Chapter 2, conflict arose in the Flores family when a powerful relative with ties to the gangs sought retribution against Ernesto for Erbesto's alleged actions against him. The family decided to send Ernesto to the United States with a guide called a coyote, both for his safety and in the hope of better opportunities there. The short section entitled "The Churn" takes place in Reynosa, a Mexican border town. The readers see how dangerous these places are for migrants who are often targeted by thieves and drug cartels. In Chapter 3, the Flores family decided to send Raul north as well for his safety. Raul and his guide were attacked and robbed on their journey north before Ernesto and Raul are reunited in Mexico. They traveled to Reynosa, where Ernesto had an unknown traumatic experience, about which he then refused to speak. The twins eventually crossed the Rio Grande together on a raft and entered the United States.
