I don't think she had vampire blood in her system, so I think she's dead now :( in an interview with Susan Walters (who plays Carol) she was showing that now her time on the show is over, so I think she's gone
what a pity, would have been interesting to see if Carol completes the transition or if she wants to die like Bill Forbes. And it would be interesting to know which vampire blood she drank. But let's just forget about that.She's dead, that's it. Rest in peace, Carol Lockwood.
