We've already watched one scene from tonight's season premiere of The Vampire Diaries. Are you ready for a few more?

In the following video, producer Julie Plec goes inside "The Birthday," explaining where various characters stand, while we are then treated to shots and conversations of those characters on the episode. What do we learn?

Jeremy will share the secret of seeing his ex-girlfriends; Caroline and Tyler will be trying to remain friends, despite their "sexual tension;" and, as Plec puts it, Stefan is with Klaus, who is "running the show... and Klaus is bad!"
