Kristina is the female Morgan--a character with no purpose except to complain and annoy the audience. I believe they are going to toy with a Griffin/Sasha pairing, if they actually remember he's on canvas. HAHA! I guess this is a way of keeping Grandma Carly unnaturally young. I figured she was just going through menopause like Blanche Deveraux when they first threw the story out there.
