"I don’t think it’s an emotional, rash decision," Emmerich continued. "I think it’s a calculated chess move that he feels must be made. It’s a Cold War, and he’s made it clear, he’s drawn a line that unless Amador is returned in health to his job there will repercussions, and if you don’t follow through with that threat then you lose all credibility in the future. So I think in some way I think that’s in fact what drives Stan to do that."
Stan's other big story involves his budding romantic relationship with Nina, the Soviet secretary he's recruited to spy within the Russian embassy on behalf of the FBI. While searching for Amador, his approach to Nina took an icy turn.
"I think Stan feels certain that the Soviets are behind the missing partner, that somehow they’re involved, they’re connected, and Nina is an employee of the residenteur," he said. "Nina is a Russian spy, so I think Stan rightly assumes that she would be privy to some of the events that are taking place, would have information about what operations they’re executing. And when it comes so close to home and his partner is missing I think he assumes that she must have some information, or at least access to some information that would help him find his partner.
"And in that moment, although I think he has obviously sincere feelings for her, and although he’s been able to turn her and have her help him on the FBI side, she’s a Russian spy living in America working on behalf of the KGB. So his sort of dogged determination and the tonal shift that happens when he goes to see her after Amador is missing is about the reality of the fact that whatever his feelings for her are personally they are outweighed dramatically by the fact that his partner and fellow American is in dire jeopardy, and he’ll do anything he can at that point to ensure the safe recovery of Amador."
