Tensions mount as Catherine, Orlo, Velementov, Leo, and Marial try to get regional counts on board with the coup. A few of the men end up killed. When a body is discovered later, Peter decides to torture everyone at the palace to find the murderous traitors. Marial buckles under the pressure and confides in Archie about Catherine’s plans. Catherine realizes she is pregnant.

In exchange for a return to her status, Marial betrays Catherine to Peter and tells him that she is pregnant. Catherine realizes that the only chance for a greater Russia is to fight, without Leo. The battle begins.
