The Vampire Diaries season 5 finale is just one week away and according to one of the stars it will be the best one yet.

Elena And Damon Will Go Through 'Ultimate Test' On Shocking Finale?

"Oh God, it's huge," Kat Grahams, who plays Bonnie, told E! Online. "Everyone's going to be up in arms. We've had some pretty big season finales, but I would definitely have to say this is definitely one of the biggest we've had."

While she confirmed that there's going to be some major deaths coming, Graham added, "It's what happens with them that matters."

Elena And Stefan Will 'Work It Out in The End'?

Graham's character is currently on the "Other Side" and fans will discover on Thursday night's episode that there really is no spell that can bring her back as the realm is quickly diminishing. Does this mean Bonnie and the others trapped on the "Other Side" will soon be gone for good?

Executive producer Caroline Dries recently told Entertainment Weekly of her "desire to get rid of the other side" and the possibility of Bonnie leaving for good.

"Pushing toward the finale, they have a united cause because the travelers are trying to rip away their home," she told the magazine of the Mystic Fall gang. "In the meantime, the other side is falling apart, so the question is, what's going to happen to Bonnie? What's going to happen to our friends who are over there who we occasionally check in with? Do they just go away like Vicki did a few episodes ago?"

-- The Vampire Diaries season 5 finale airs on May 15 at 8 p.m. ET on The CW.
