SEASON THREE: Marat travelled to Russia to see his father to help with the family company, Kremlin Diamonds. There, Marat revealed that he was in love with Stacey, and Yuri uneasily gave him his blessing. Shortly after, Lydia called Yuri and asked him to bring the Kremlin over to Blackmore Ltd. from Rockwell Mining. Yuri advised her that he would only if she submitted her request in person. Yuri then, secretly, called Lucinda and told her that everything was on track. Lydia's plane to Russia crashed, and she was presumed dead. When Stacey took over Blackmore, she realized that Lydia was trying to gain control of the Kremlin and she got Marat to help her with securing the deal. Little did she know that Lucinda agreed to pay Yuri's contract cancellation fee with Rockwell. Turns out, Yuri was helping Lucinda with her plan to hold Lydia and Houston Blackmore hostage. When Sabine saw Yuri in town, she freaked out that her boss – he was paying her to spy on Rockwell – was in town. He advised her that he would be leaving shortly, but Sabine wondered what was going on after she heard Lucinda and Yuri speaking about Lydia.

SEASON FOUR: Yuri encouraged Lucinda to stay calm about holding Houston & Lydia hostage, as he helped Lucinda with her plan. He returned to Moscow but returned for the masquerade ball at the Rockwell mansion, where Sabine was about to give him some information on Rockwell Mining before the bombs went off.

SEASON FIVE: Yuri was found dead following the bombs.
