Adiós, Muchachos

Plot:

All hell breaks loose when it's discovered that Dr. Kurian's Z-Vaccine doesn't work at all! Instead of building an immunity to the Zombie Virus, the bad vaccine actually makes anyone inoculated susceptible to Murphy's unique brand of mind manipulation. Vasquez gets caught in his plot to kill Escorpion and is sentenced to death by La Reina. Murphy uses mental manipulation to position Warren as La Reina's new second in command. Warren frees Vasquez just in time to watch everyone who was inoculated succumb to a bizarre new form of the Zombie Virus.
