I think it would be a great storyline if Viv continues to believe Mia is Carly’s daughter and goes after her with guns ablazing. They could likely take it so far that she even kills Mia. After all, Mia isn’t that big of a character to the show that she couldn’t be sacraficed.
Then, after the deed, Vivian and Victor find out their mistake. Then there could be some real disasterous effects. The way these writers carry things on ad infinitum, I don’t believe we’re going to see any earth shattering events for a while anyway.
And did anybody else find that conversation between Carly and Mel today somewhat unbelievable?
