was killed by a fungal growth known as Aspergillus. Eladio escapes as he is being deported, killing a truck driver in the process. A clinical exam on the driver shows his death was caused by a rapid growth of Trichophyton — the Athlete's foot fungus. Scully brings samples of the fatal fungi to a mycologist who discovers that their abnormally rapid growth was caused by an unidentifiable enzyme. This revelation leads Scully to suspect Eladio of being an unwitting carrier of the enzyme, necessitating his immediate capture. Eladio, seeking to return to Mexico, meets with his cousin Gabrielle to ask for money. He works with a construction foreman for the day to make the money. Soledad comes after him, seeking to kill him, but finds the foreman dead. Eladio escapes in the foreman's truck and heads to the grocery store where Gabrielle works, spreading the fungal growth. The agents later confront Soledad at the supermarket, discovering another dead victim of the fungus. Eladio returns to see Gabrielle, but by now has grown deformed from the fungus. Gabrielle, afraid of him, gives him her money and lies to the agents about his location when they come to see her. In actuality, Eladio has returned to the camp where Maria died, where Lozano tries to spur Soledad on in killing his brother. Soledad finds he can't do it, and Lozano struggles with him, being accidentally killed when the gun goes off. Soledad becomes a carrier of the fungal growth himself and flees with Eladio towards Mexico. Production "El Mundo Gira" was inspired by writer John Shiban's memory of the "long lines of migrant workers in the strawberry fields alongside the freeway" in Greater Los Angeles area. When Shiban started to work on his script, he combined these memories with an idea about a highly dangerous fungal infection, along with elements of the "Chupacabra" Latin American folk myth (which he had originally heard about in an article in the Los Angeles Times sometime prior). Initial versions of the story featured a child and later a truck driver as the carriers of the contagion before Shiban settled on the character of Eladio. As Shiban's story was coming together, series creator Chris Carter noted its telenovela/soap opera-like nature, and so it was decided to title the episode "El Mundo Gira", which means "The World Turns" in Spanish and is a direct reference to the popular
