Ever since Candice Accola, who portrays the character of Caroline Forbes in 'The Vampire Diaries,' fans of the supernatural television drama series have been expecting vital changes in the storyline when the show returns to The CW for its seventh season this fall. Many fans are even predicting that the production house may kill the popular character Caroline, while most are of the view that the actress' pregnancy may bring in some troubles for the vampire series.

Speaking to TV Line, Accola said, "Production has known about our exciting news and there's been a lot of support. They already knew where this season was going, and it's kind of the same as every other year."

A report in IB Times states that the 28-year-old actress, who married Joe King in 2014, has announced her baby news through an adorable Instagram post on Aug. 31.

Nevertheless, the news of Accola's pregnancy news may mean trouble for the extremely popular supernatural series since the lead actress of the show Nina Dobrev (Elena Gilbert) has already quit 'The Vampire Diaries' after Season 6. On the other hand, Accola is of the view that the show creators are the best people to envisage the future of the show.

Accola told the publication, "We start the beginning of the season asking the writers a lot of questions about what's going to happen. Then halfway through the season, it's completely different. ... Julie [Plec] and Caroline [Dries] are the best people to ask about [how her pregnancy will be included in the show.] To be honest, I'm along for the ride just like the viewers are."

Meanwhile, the American actress and singer also shared some spoilers about Caroline's character in 'The Vampire Diaries' Season 7.  She said, "We're going to see Caroline get her bite back. We'll see her coming in as a badass, and sometimes she might act without thinking things totally through."

In the finale of Season 6, fans saw Elena slipping into a deep slumber after Kai put a magic spell on her, and relating her sleep with Bonnie's life. Then again, Lily Salvatore brought her 'heretic' family back to Mystic Falls, and they are now on a rampage.

In the upcoming season of 'The Vampire Diaries,' fans will see how Damon deals with the unexpected changes. In the meantime, Lily will try to create differences between the Salvatore brothers - Damon and Stefan. Stefan will be seen playing an important role, as he comes to know about Lily's wicked plans and saves his elder brother.

'The Vampire Diaries' Season 7 premieres on Oct. 8 on The CW network.
