Vampire Diaries 24/7

Dobrev has been working double duty this season as both Elena and Katherine. She was in nearly every scene of "Memory Lane," but she's not complaining about the long hours. Does she even need sleep? "I'm a vampire, no," she laughs. "It's a lot of hard work. It's really awesome, and I'm one of the luckiest people I know. It's a lot of hard work, long hours... we shoot a lot of nights, and dual characters are pulling double duty."
