Kat Graham plays Bonnie Bennett on The Vampire Diaries. Season 8 will be the last for The CW TV show. At least one death is expected, but the actress teased a major character may bite the dust by the midseason finale.

Who could end up getting killed when the series returns?

Not everyone will get a happy ending in 'The Vampire Diaries.'

It would be nice if the core characters in TVD would live happily ever after. However, Kat Graham teased at least one cast member will die halfway through the season.

Not only will someone die, but it will be a major character. Considering that the main character list has dwindled over the years, which one could have a tragic death?

Will Bonnie die in 'The Vampire Diaries' season 8?

One theory is that Graham's character may leave the Television show sooner than expected. A few months ago, the actress announced she was leaving TVD after the season 8 finale.

Now that fans know this season is the last, will Bonnie Bennett exit the show in a tragic way?

Damon may not survive 'The Vampire Diaries.'

Another speculationis that Damon Salvatore, played by Ian Somerhalder, mightnot be saved. As viewers recall, he and Enzo (Michael Malarkey) were taken over by the creature inside the vault.

Although "Delena" fans are hoping Damon and Elena reunite, it may not happen. The two missing vampires must be found and even if they are located, can they be saved?

Or will TVD fans find that it is too late?

Elena to die after waking up in 'The Vampire Diaries'?

Nina Dobrevis supposed to return to The CW series before the final episode. For the past few years, Elena Gilbert has been in a deep sleep. Her life is tied to Bonnie's.

As long as Bonnie is alive, Elena stays comatose.

However, if Dobrev's character wakes up, then that means Bonnie dies. Fans are looking forward to "Delena" reuniting.

However, could she die right after waking up?

Let's hope not because that would be a huge letdown after all the hype of Nina returning to TVD.
