Every line referring to the "FBR" or "CEA" is dubbed, often quite obviously. The actors were actually saying "FBI" and "CIA," but at the behest of the actual agencies the names were changed in post-production.
Sidney talks with Kropotkin while dinning. He says "who arrested your mother ?", Kropotkine answers "my father".
Sidney is then seen with his left fist on his chin and he says "Hmmm...tell me about your mother". Between the "Hmmm" and "talk", he is now wiping his mouth with a napkin.
After the dinner on the boat, Sydney leaves the dinning-room, followed by Kropotkine, who is not wearing a captain cap.
When the two are going backstairs, we can clearly see that Kropotkine has his two hands empty. In the next scene, in the hallway, he has the cap on his head.
