First, your link for chapter 4 doesn't work, maybe that's intentional ;) Anyway, thought you'd like to know.

I do feel bad for Natalia, she's realizing the actual reality of her mistake. And that maybe just maybe she can't do it. Was it the feeling of the moment with Olivia where they both felt their feelings and that one touch meant everything to her while this thing with Frank made her want to scrub herself clean.
