The Vampire Diaries season 6 is coming to an end, and fans will sure be grieving over the exit of their favourite star Elena Gilbert, who will say her final goodbye in the finale episode titled: I'll Wed You in the Golden Summertime.

Until now, fans were of the opinion that Nina Dobrev's character will turn human with Bonnie's cure for vampirism and then may leave Mystic Falls forever.

But the recently released promo of the season 6 final episode of The CW supernatural series narrates a shockingly different story. It is hints at Elena's death!

In the penultimate episode, the fans saw the return of the evil Kai from the prison world, who crashes Alaric and Jo's wedding and in a shocking twist, stabs Elena who is now human.

In the promo, the Gilbert daughter is seen hospitalised in an unconscious state, while the love of her life, Damon (Ian Somerhalder) appears distraught asking the malevolent witch, "What did you do to my damn girlfriend?"

Caroline (Candice Accola), Bonnie (Kat Graham) and Stefan are also shocked with the entire incident. Later, they all are seen standing near a coffin and Caroline asks everyone to "join hands, close your eyes, and just let her into your thoughts".

This clearly proves that Elena will indeed be killed off on the show.

Meanwhile, the malevolent witch's return, is not good news for Damon and Bonnie, as they are responsible for the trauma he suffered at the hands of the blood hungry vampires in the prison world of 1903.

To know how things unfold in what could be a highly emotional episode, since fans would see the end of the Delena romance, watch The Vampire Diaries season 6 finale which airs on 14 May on The CW Network.
