First of all, Ajay was Charles’ second-in-command, his lieutenant, his henchman. He lured in Western travellers, and helped Charles commit his deadly crimes – stealing thousands of dollars in travellers’ cheques from victims. They committed the first recorded murders in 1975. In episode one of The Serpent, we see the duo drug American Teresa Knowlton. They stole from her, changed her into a bikini, and drowned her to make it look like her mistake. Ajay helped Charles commit a series of murders, robberies and passport thefts, according to the Nepal police and Interpol. He is also suspected of burning the victims’ bodies to prevent quick identification.
