Code Talker identified the strain infecting Mother Base as being a strain that targets speakers of Kikongo, and 48 hours after this discovery, all new infections of the parasite had stopped. Code Talker remained on Mother Base to continue his parasite research for Diamond Dogs  and later discovered that Quiet was infected with the third English strain of the active vocal cord parasite; she had deliberately been infected by Skull Face in order to act as a "vector" and guaranteed to kill Venom Snake even if conventional assassination methods failed. Conversing in Navajo, Quiet informed Code Talker that she had decided to remain silent to avoid killing Venom Snake and the others on Mother Base despite wanting revenge on Snake for her condition.
It is normal to be nervous or unsure around unfamiliar animals. In addition, there are a number of common myths about snakes. If you have never handled one, you may be nervous that it will be slimy or disgusting or afraid that you will be crushed by a constrictor. These fears are common and can be dispelled simply by gaining more personal knowledge about the animals. The symptoms listed above, on the other hand, are out of proportion to normal nervousness and may indicate an actual phobia . Only a mental health professional can make that determination.
