'The Vampire Diaries' Season 5 Preview: Doppelgangers Are Running Amok

It's been a long summer of waiting for the lovers of American TV drama series "Vampires Diaries", but the new season of The Vampire Diaries is nearly here. When we last left the grads of Mystic Falls in the season four finale we discovered some pretty major shockers. Silas and Stefan are doppelgangers and Katherine Pierce is actually human.

In the first promo for the new season, there's plenty of trouble a brewing. For starters, Delena's trading "I love you's" like crazy, newly-alive Jeremy is duking it out at school, and Katherine's hair could use a good washing. Oh, and who is it that fatally crashes into that light pole?

Tune into The Vampire Diaries season premiere on Oct. 3.
