when florian returns to the family farm and looks in the well, in the reflection at the bottom he has his hair shorn like at the end of the film
I see it as imparting inevitability; his choices and others have led to the terrible outcomes present and future . Remember, Florian subconsciously already knows that something it very wrong at home. His family’s lying dead around the corner, and he’s going to find them. The future he sees in the well is already his present.
