Question: is elena still a vampire in season 6

Answer: No, Much of Elena's story revolves around her relationships with vampires Stefan Salvatore and his older brother, Damon. It is revealed that Elena is a Petrova Doppelgänger, which is thus responsible for her being identical to her ancestor, Katherine Pierce (née Katerina Petrova). This also has the implication of making her a supernatural creature. Dobrev portrayed the ``conniving'' Katherine as well, who is opposite of Elena. The actress stated that it has been a challenge distinguishing the two, and enjoys playing them both. In the television series's fourth season, Elena becomes a vampire and deals with the struggles that come with her change. She took the cure and became human again towards the end of the sixth season. In the finale of the sixth season, Kai linked Elena to Bonnie's life by magic. Elena will only wake up when Bonnie dies in around 60 years. She was locked inside the Salvatore tomb, which was changed in the seventh season, and was relocated in Brooklyn, New York. In late 2016, when it was announced that the eighth season would be the final season, Dobrev was in talks about returning to the television series to reprise her role in the final episode. After much speculation. Dobrev's return was confirmed on January 26, 2017, via an Instagram post. Dobrev appeared in the final episode of the show as both Elena and her evil doppelgänger Katherine Pierce.
