The Vampire Diaries, Nina Dobrev has been pulling triple duty as of late with three versions of herself running around the Mystic Falls universe. However, now that Amara is dead that only leaves Elena and our poor human and dying Katherine. Dobrev spoiled on Katherine's current peril, Nadia and a possible fourth doppelganger.
"As Katherine grows weaker, Nadia is fighting to take care of her and have her in her life," Nina Dobrev spills. "You learn [Katherine] wants to have that relationship, but she keeps screwing it up." But it seems like Dobrev's workload might not lessen anytime soon as she spills to us, "Now they're alluding to a fourth [doppelgänger], although we haven't done anything, so I can't say if that's going to happen for sure."
