Phoebe Tonkin's character, Hayley, will go through major changes when "The Originals" returns with Season 3 now that she has been cursed to live as a wolf except for on the rare occasion that there is a full moon.

During the "The Originals" Season 2 finale, Klaus cast a spell on the mother of his child in order to win Dahlia's trust before defeating her. Under the curse, Hayley will be forced to live in wolf form unless there is a full moon.

Although Klaus' plan of deception helped him send his evil aunt to the underworld, Hayley won't be very understanding now that she has to live with the ramifications of his master plan.

"Hayley's not going to be able to forgive him easily for what he's done," the actress told TVLine at The CW Upfront presentation. "Even if he did it for the good of his baby, I don't think he did it in the right way. He should have let Hayley know that's what he was doing so she could have been part of the plan. But he didn't do that, so now, [she's] pissed."

Because of the curse, "we're only going to see Hayley once a month" when she can return to her human form.

"I hope that at least one episode will be the full day when I'm human," said the series star, adding that "it could be really cool" to see "Hayley in wolf form."

Executive producer Michael Narducci also dropped spoilers about the next season, promising that although Hayley has been turned into a wolf, viewers have "definitely not seen the last of her."

"Built into the DNA of the show is the Mikaelson family. There's also this young baby, and that baby has a mother, and she has a clear tie to Klaus and a clear tie to Elijah; she's fundamentally important to the show. Even though she's in a worst-case scenario, we definitely have not seen the last of her," he said.

"We have to resolve what has been done to her and what it means to her, and if there is any cure to her situation, we'll have to deal with that as priority one. Whether that improves her condition, or significantly worsens it, I can't say."

 The showrunner also confirmed that Tonkin is "not being written off the show."
