'True Blood' Star Deborah Ann Woll On Jessica's Faerie Massacre

Bad baby vamp! Things took an unexpected turn for lovable ginger Jessica Hamby (played by Deborah Ann Woll) on Sunday's "True Blood" episode, when in an attempt to help her maker, Bill, extract blood samples from Sheriff Bellefleur's four faerie daughters, she accidentally, well, ate them. Not exactly how the phlebotomists do it, Jess!

It was arguably the darkest moment in the bloodsucker's short life, but one Deborah told Hollywood Crush she relished.

"[I was] really excited," the 28-year-old said of her reaction to reading the episode's script for the first time. "You know, for an actor, the best thing in the world is when your character screws up big time because it allows your character to grow. And that's the best thing."

How Bill (Billith?!) will ultimately clean up the mess (literally and figuratively) is yet to be seen, but one thing's for certain: The vampire needs his spawn as much as she needs her maker.

"I think he's all she's got," Deborah explained of her character's loyalty. "Hoyt's left. Jason's hit his head really hard and is figuring that out. She's alone, and she's gotta hold on to something, and he's all that's really left."
