With tensions high in the Argentine camp, an argument breaks out between Sgt. Agapito Quitana and Dr. Deseado, resulting in the two coming to blows. Deseado then steals a gun and attempts to shoot Agapito, only to be shot dead by another soldier, Cruz. After consoling him, Agapito orders Cruz and Escobar to bury Deseado's body. Later, an American commando unit led by Childs restrains the Argentinians for blood testing. During the testing, Escobar, the next-in-line to be tested suddenly melts into a liquefied mass, which attacks and engulfs one of the Americans. Childs then torches the creature, though he burns down another hut in the process, much to the annoyance of the Argentinians.
