Jim Sterling is beaten by Spencer in the bar when he comes in the car yet later he has no marks or cuts on his face.
When Sterling and Eliot are fighting in the bar, there are two takes of the scene where Sterling hits Eliot twice with the telescopic baton, taken from slightly different camera angles. They are both shown - the first one is shown, then there is a cut to Nate and Tara, and then the other take is shown. You can tell that they are two different takes by watching the woman in the background.
Jim Sterling says "the Ukraine". Since 1991 the term has fallen out of favor with "Ukraine" being the preferred name of the country.
Before leaving Nate's house to travel to Kiev, Nate calls Eliot the Retrieval Specialist, and tells him to retrieve his wife from jail, when Maggie is his ex-wife.
