Harry's advice to Vincenzo - question with spoilers
At the wedding, Harry tells Vincenzo that Maria loves him and to not abuse this. He tells him this knowing from Maria that Vincenzo had only "kissed her hand".
I wondered if in 50's subtext Harry suspected Vincenzo of being a homosexual and was telling him that he had to do his husbandly duty by his new wife.
This didn't occur to me during the scene but later in the hotel room when Maria tells Harry that Vicenzo is impotent, Harry looks so striken, piecing it together - it seemed not just out of pity for Maria and Vincenzo but as if this information pieced everything together and Harry realised he'd made a mistake,
Later, towards the end, Harry has a piece of dialogue with Vincenzo in which he alludes to getting something wrong about his character... I cant remember quite how this goes.
Am I reading this incorrectly? Interested to know if anyone else thought this was underlying Harry's thoughts on Vincenzo's motives in not having a sex life with Maria.
