This scene again focuses on Ethan’s deception to Julia about his job.   It ends with them getting married. It is very rare in spy films for agents to get married. It is even more rare for the starring agent to get married.   As mentioned earlier, James Bond marries Tracy and that’s about it. It is even more poignant later in the series with the film Mission: Impossible – Fallout when we see what has happened to Ethan and Julia’s relationship.
