Here is a little scoop from Fancast:
(SPOILERS)

‘The Vampire Diaries‘ sure is drawing out these flashbacks. We still have yet to see how Damon and Stefan actually died, or the burning church with 27 vampires trapped inside. Will we see those events before the end of the first season? – Heather
You will certainly see something. All exec producer Julie Plec would tell me is, “There will be one more flashback episode this year.”

I love the flashback episodes I wish there were more!

E! gives us a little Vampire Diaries scoop.

It isn’t much, but it’s something!!

Marlene in Columbus, Ohio: Vampire Diaries! Please, something, anything. I can’t stand the wait.

We just chatted up Jasmine Guy, and she tells us she’s “having a ball” playing Bonnie’s grandmother and will be back sooner or later. She also hinted at a bigger picture storyline arc for the 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.” She also calls the show’s producers “elusive” and that she learns what she’s going to do when she gets on set. They’re good with the secret-keeping, those Vampire peeps!
