Phoebe Tonkin Introduces 'Vampire Diaries' Fans To Her Character Hayley

A new werewolf is going to be coming to Mystic Falls tonight, and she's going to have a familiar face. "The Secret Circle" star Phoebe Tonkin is making her long-anticipated arrival on "The Vampire Diaries" tonight as a friend of Tyler's named Hayley.

In anticipation of tonight's episode, "The Rager," MTV News sat down with Phoebe to ask her about her character. We don't know much about Hayley going in—and no, she's not Faye Chamberlain in werewolf form—so we had Phoebe catch us up to speed on what role she'll play in Tyler's life and why she's come back into it.

"She is someone from Tyler's past that she met when he was breaking the sire bond and she was a big part of helping him do that," Phoebe said. "She's a world traveler. She lost her parents very young. She doesn't know who her parents are or where she got her werewolf gene from. Yeah, she's like an eclectic free spirit."

Sounds like she's exactly the type of person that Caroline won't want in Tyler's life. Fortunately for our favorite cross-species couple, it doesn't sound like Hayley's motives are to turn Tyler into her new boytoy. Phoebe told us that her character has headed to Mystic Falls on a more top-secret mission.

"Hayley may have a different motive for trying to help Tyler," she teased. "As I said, she lost her parents when she was very young, so she's got some questions that she wants answered."

"The Vampire Diaries" airs tonight at 8 p.m. on The CW.
