So I was thinking about Natalia Livingston's new character "Rebecca" and who she she could possibly be related to that has her coming to Port Charles. What if she's somehow involved with the Russian story line. She could be Karpov's daughter looking to seek revenge for his death, or Sasha's sister or daughter (depends on how old we're to believe Shasha was) seeking revenge for her death.
In a glimps of what I have saw...Natalia has cut her long beautiful hair for this character to her shoulders and is wearing alot of dark eye make-up...unlike Emily's angelic look. So my take is she'll more than likly will be "rough around the edges."
