At what point do you think Silvana came to Dickie for help?
When do you think this would have taken place in the film? Does it make it clear in the book?
Would it have been at this moment as well when Dickie is told she is pregnant? I'm putting two and two together and assuming that the baby is his and this is why she came to him for help. Being informed of that you'd expect him to be rather affected by the news yet there aren't many moments before her death when he isn't enjoying himself. I did think in the scene when he walks in on Tom dancing in his clothes, he almost looks like he's come in after a bad night, exacerbated by seeing Tom dancing, and wondered whether he could have met with Silvana along the way? Or could it possibly be as recently in the film as sometime after she's waiting on the rocks looking at them on the boat?
