'Vampire Diaries' Kat Graham Weighs In On Which Of Jeremy's Ghostly Girlfriends Is The Biggest Threat

Deadly vampires. Cunning werewolves. Powerful witches.

Over the past two seasons of "The Vampire Diaries," Bonnie (Kat Graham) has faced 'em all with ease. But now, she's up against an entirely new kind of enemy: the ex-girlfriend. Two, actually. Both of whom have come back from the dead to haunt her boyfriend. Talk. About. Baggage.

We caught up with Kat recently at the Television Critics Association red carpet where she told us that she's not yet sure when Bonnie will find out about Jeremy's (Steven R. McQueen) recent "visitors." But if or when (we're going with the latter here) she does, fans can definitely expect to see a little of Bonnie's possessive side come out.

"We've seen her crushing, falling in love but we've never really seen her be the jealous girlfriend," Kat told MTV News. "So that would be kind of cool to explore."

But with both Anna (Malese Jow) and Vicki (Kayla Ewell) back in the picture, which ex should Bonnie be more weary of? Kat thinks both could pose a threat to her relationship.

"I feel like his relationship with Anna is a bit more developed than his relationship with Vicki," Kat said. "But I also think he really loved the character Vicki, so he wanted to see that through and he never had that opportunity. So it could go either way."

Well, here's hoping it goes Bonnie's way, because as much as we love Anna and Vicki, we think Jeremy deserves a living, breathing gal by his side.

Which ex do you think poses a bigger threat to Bonnie and Jeremy's relationship? Do you want him to get back together with Anna or Vicki? Or stay with Bonnie? Tell us in the comments and on Twitter!
