- "I am not István!"
- ―Lorena to Bill[src]
He used Lorena to entice men into her chamber, and then he would "defile them in unspeakable ways" according to Bill Compton. It is unknown why Lorena left him, but it is most likely because she had fallen in love with Bill and didn't want any harm to come to her progeny. István's current whereabouts, and whether or not he's still alive, are unknown.
- István has only been mentioned on the True Blood series.
- István is a hungarian name and means Stephen.
- István could be a member of Sanguinista, taking into account his opinion about humans.
- István as a hungarian name can be a reference to the infamous Count Dracula. As his original name was Vlad Țepeș, and Vlad is the slavic version of the name István, and the infamous lord was born in Segesvár, Hungary. This is also in correlation with the facts and horror stories, that István/Vlad/Dracula was a sadist.
