Kay Adams... the scarlet Woman?

as we all have talked about, Kay Adams has been wearing to much red for our tastes, lately.

We have labelled her as the "Scarlet Woman."

Now for the fun part, my only question for this topic: is she?

From the observation of the film, wiki sources, and blogs I see Kay with the style of being illustrious and un - racy to be a lady of the evening. She strays too much from the rest of the family, prays for her husband, and stands out in their crowd. her non-italian feel contradicts the Corleones. I find it very peculiar that her apparent foreshadowing is the opposite of her portrayal in the film.
