When Barley first meets Katya, they're in the big square and he tells her that 3 years ago he was nearly arrested in the same place for suspicion of being a spy. Katya asks "were you?", and Barley replies "of course not" .. He then goes on to explain "a soldier and his girl friend..." followed by a short pause during which Katya smiled satisfactorily, but then Barley continues to explain "..asked me to take a photo of them."! Katya should have waited until Barley finished the whole sentence before smiling (laughing) with satisfaction.
