It's hard to follow the differences but I guess must have used the right patch as I'm glad I seen the bathtub scene. I like her spicy scenes, it's hot when she teases. The sister part is just icing on the cake, not because I would have such feelings for my non-existant sisters, but them already having a long-lasting strong bond, love and loyalty, makes the romantic part creeping in kinda more explosive, or something.
