As Kai offers his niece Josie a bottle of flavoured vodka, he makes a reference to his favourite drink Zima. The alcoholic beverage was first released in 1993, which meant Kai had plenty of it in stock during his time in the 1994 prison world. When he tried to escape the prison world with Bonnie and Damon in TVD season six, he even put a bottle of it in his backpack in case he got "homesick."
