I think Vivy has said more than once that she intends for Carly to pay the ultimate price. Though perhaps, she has not actually said the words, "I’m going to murder her". I would find it highly amusing if Vivian re"buried" Carly. Bo would of course have to come riding to the rescue.
However, I think it would be an even better scenario if someone else from Carly’s past "rescued" her from the grave, someone that we would not suspect, only this person would be interested in exacting revenge not rescue. Then, (wait, not finished yet with twisting), Carly’s daughter (whomever she turns out to be – not saying incase some have not caught up with SL yet) would have to really rescue Carly from the clutches of _ _ _ _ _ _ _ _ _!
