As Bonnie's mysterious, spell-loving grandmother, Jasmine Guy says she's "having a ball" on The Vampire Diaries.

That's great and all... but how about a few hints about what's to come on The CW series?!?

"There's this whole inner life between the witches and the vampires where there's this pact between the two forces that they won't expose each other. So I'm excited to explore that," the actress told E! News.

As for any other Vampire Diaries spoilers? Guy referred to the show's producers as "elusive" and said she doesn't know what's happening in the script until she arrives on set.

That's too bad. It's also too bad that the show doesn't return with new episodes until January 14.

But viewers can catch up with a 10-episode CW marathon throughout the week of December 14 and they can always discuss the series in our Vampire Diaries forum.
