Unlike his wife, Igor does not have a close relationship with Oleg, favoring his son Yevgeny instead. When Yevgeny is killed in action in Afghanistan, Igor unsuccessfully pressures Arkady to force Oleg's return to Russia prematurely.
Oleg and Igor grow a little closer when Oleg voluntarily returns home to comfort his mother in 1984. Igor ultimately shares some of his perspective on painful family events, including that he remained faithful to Yelena when she was imprisoned for several years prior to Oleg and Yevgeny's births.

Igor assists Oleg when he returns to the US in 1987, ostensibly to take classes in urban transport, but in reality to make contact with Philip regarding a KGB plot to discredit and overthrow Gorbachev. Oleg calls Igor periodically with coded messages, which he then relays to Arkady.
