"Alejo slid through the bushy branches, the tangled twigs scratching his face, and he was ready to jump when he felt the mist. He shut his eyes tight to the mist of black afternoon. At first it was just a slight moisture until the poison rolled down his face in deep sticky streaks", (76-77).
"With the help of Perfecto Flores, Gumecindo carried his cousin into the bungalow and lay him on the pile of blankets which made up a bed. After Petra propped a pillow for him, Alejo already felt better", (98).
"A broken water pipe bubbled up and muddied a section of the road that Perfecto didn't notice until the wagon's back tire dipped and sunk into the deep chocolate mud", (128).
"Estrella emerged from the glass doors of the hospital not knowing quite what to do with the emptiness in her hands. The twins saw her stand there, from the rearview window, just like that, without Alejo," (155-156).
"When her eyes became accustomed to the dark and the moonlight paved a worn pathway toward the barn, Estrella knew what to do. The weight of night did not affect her eyesight; her eyes grew like the pupils of a cat to absorb every particle of light", (170).
The LaBrea Tar Pits symbolize Alejo's death. If stuck in tar you eventually sink down and suffocate, just like how Alejo felt once he was sprayed with the pesticides.
