'The Vampire Diaries' Season 8 spoilers update: Nina Dobrev's return will determine show's renewal for Season 9?
Many fans of Elena Gilbert's character are hyped for the eighth season of "The Vampire Diaries" as the show's alum, Nina Dobrev, is set to return for the series. However, the length of her appearance in the show is still unconfirmed. Nevertheless, many people are looking forward to seeing the former de facto female protagonist of the show going back to life.

It can be recalled from Season 6 that Elena and her best friend, Bonnie Bennet (Kat Graham) were placed under a jinx by the show's former villain, Kai Parker (Chris Wood). The jinx would place Elena in a deep sleep and there would be no physical or magical means of waking her up from the cursed slumber. The only way to wake her up is through Bonnie's death. The main characters of the show have then decided to let Bonnie live the days remaining in her mortal life while Elena lies asleep in a protected coffin.
If ever Dobrev returns to reprise her role, the supposed curse cast on her character will now be lifted in Season 8.
Meanwhile, the return of Elena Gilbert may also have a big implication in the future of CW's supernatural romance drama series. As reported by Celeb Dirty Laundry, the reception of the audience upon the return of Dobrev in the show will be monitored, as Elena's appearance in the show will determine if "The Vampire Diaries" will be renewed for a new season. If ever the show suffers from low ratings despite Dobrev's re-entry, CW may no longer renew "The Vampire Diaries" for a ninth season.
"The Vampire Diaries" executive producer and showrunner Julie Plec said in an interview with TV Line that she wants to see Dobrev returning for Season 8 to reprise the role of Elena. She also revealed that the show still has a big story untold for the character when Dobrev first left the show in Season 6.
If Elena does return alive in Season 8, then Graham's character may finally end up dead. This could be possible as the Hollywood Life reported that Graham will be leaving the series in the upcoming season. In the print, Bonnie may sacrifice her life for Damon (Ian Somerhalder) and Enzo (Michael Malarkey) who are now enslaved by the creature in the Vault from the Season 7 finale.
