The gig is nearly up for an Elena-possessing Katherine Pierce (Nina Dobrev) on The Vampire Diaries. How will Stefan (Paul Wesley) react to the reveal that Katherine has been pretending to be Elena since her own body’s death? One word: desperation.

According to the official episode synopsis for Season 5, Episode 15 (“Gone Girl”): “While Nadia remembers her centuries-long search for her mother, Stefan, Caroline (Candice Accola) and Matt (Zach Roerig) come up with a desperate new plan to save Elena’s life.” So, Stefan isn’t the only one desperate to get Elena back before she’s lost to her loved ones forever — but, we’re guessing his motivation is particularly complex given that he may or may not hook up with Katherine-pretending-to-be-Elena in Season 5, Episode 14 (“No Exit”).  

So, what exactly does this “desperate plan” entail? Our guess: it has something to do with Damon, aka the neighborhood vampire cannibal. The serum Dr. Wes injected him with not only inspired a bloodlust for vampire blood, but it made him ever stronger and faster than he was before — i.e., potentially stronger and faster than any other vampire. If that’s the case, he is a real threat to any of the characters on the show, and that can be a useful weapon, as well as an imminent threat. If Stefan, Caroline, and Matt manage to kidnap Nadia, they could Katherine’s daughter as leverage against her. Would Katherine give up Elena’s body to save her own daughter? While on her deathbed, she claimed that Nadia’s life was more important that her own. Was that all part of the ruse to get Elena’s body? It may finally be time for Katherine to put her money where her fanged mouth is.
