* FridgeLogic: Who exactly was that corpse in the Norwegian camp?
** One possible explanation brings this into FridgeHorror territory: [[spoiler: it was a Thing, acting dead in the hopes of infecting an unsuspecting isolated victim.]]
* FridgeBrilliance: There's a few grammatical errors throughout ''Irina's Memoir'', such as Yuri shouting "Someone help me with this man" when [[spoiler: he was restraining Kate]]. At first they are somewhat annoying... except Irina couldn't speak English, so she presumably wrote her account in Russian and had it translated.
* HarsherInHindsight: In ''Irina's Memoir'', Irina hints at her lesbianism and talks about how she kept a photo of her lover hidden because she didn't want anyone to find out. It makes sense considering this is 1982, when Gay Rights was still a very difficult subject. However, Hitchcock might not have included that element if he had known that roughly a year later Russia would pass a law against homosexuality.
