Just based on what we are seeing, or how it is perceived, Vivian will likely try and kill Mia to get back at Carly, thinking that is the real daughter. But it seems Melanie is the real daughter. Somehow, you can see Carly coming to the rescue of Mia and it might put her in Melanie’s good graces.
The new batch of Days’ writers don’t have the same inventive spirit for plots as the ones from the heyday of the show. Too much predictability and the imagination quotient has gone out the window. It will make it interesting when it comes out that Dan is the father. It would not have surprised me if the writers had stuck Bo with another child, but thankfully they did not go for the obvious plot wrecker.
