"My name is Guillermo de la Cruz," said the defiant vampire slayer and possible Van Helsing descendant — yes, Guillermo de la Cruz (Harvey Guillén) — after majestically killing a theater full of vampires in the second season finale of FX's What We Do in the Shadows

For fans of the series, it was a season-long arc for the faithful familiar to vampire Nando (Kayvan Novak), who began developing a thirst and skill for killing vampires that he kept secret from everyone. That secret was revealed during the finale's theater massacre, where Nando and fellow vampires Laszlo (Matt Berry), Nadja (Natasia Demetriou), and Colin Robinson (Mark Proksch) were present.
