The end may be near for The Vampire Diariesborn-again human, the one-and-only Katherine Pierce (Nina Dobrev). Last time we checked, she had been given only a few months to live due to her condition of aggressive aging, and no amount of negotiating seems to be helping the self-preservation expert. But there’s hope on the horizon in the form of Katherine’s biological daughter-turned-vamp, Nadia (Olga Fonda). Will Nadia be able to save Katherine?

Yes, only Nadia can turn Katherine vamp

In the official synopsis for Season 5, Episode 11 (“Fifty Shades of Grayson”), “a frantic Katherine turns to Matt for help, until she realizes that Nadia may be the one who can solve her problem.” How might Nadia be able to help her 500-year-old mama? (Besides, some good old-fashioned familial love?) Well, in this sneak peek for the ep, we see Matt asking Katherine why she doesn’t just turn vamp again to avoid a timely death. Katherine tells Matt: “Tried that. Every time I ingest vampire blood, my body rejects it.” Bummer. Vampirism sounds a bit like the world of organ transplantation: sometimes, the body will reject a foreign body. However, the chances of this happening are lessened when the donor is a relative. Could the same be true for Katherine? Perhaps, Katherine just needs the right vampire to turn her. Nadia might be Katherine’s only hope. If only Katherine had been a bit nicer to her estranged daughter...

No, Katherine is doomed

We hate to say it, folks, but we’re seriously worried that Katherine isn’t going to be able to talk her way out of this one. The title of the big, climactic 100th episode is a reference to Katherine’s life (“500 Years of Solitude”) and we know that “death will be knocking at the window.” (Don’t let it in, guys!) This might be the end for our favorite bustle-wearing vamp. As much as we’re hoping for a last-ditch, plot-twisty save in the form of Nadia’s blood, The Cure seems to make Katherine impervious to all forms of vampire blood. It didn’t just “cure” her once, it cured her for always even after the concoction was drained from her system by Silas. And, ironically, it seems The Cure will be the death of Katherine.

Do you think Nadia will be able to save her mother? Would TVD really kill Katherine off? Sound off in the comments below!
