MTV's Teen Wolf has three episodes to go before its mid-season break but fans are already buzzing about who will join the cast come January.

Arden Cho is set to be the latest edition to Beacon Hills High when the second half of season 3 comes to air. The 27-year-old will be appearing in multiple episodes, according to E! Online, and the actress began shooting on Thursday.

"@arden_cho Welcome to the home you never knew you had. Hope you packed floaties- we're off the deep end. Cheers!," tweeted Charlie Carver (Ethan) to his new co-star.

"@Charlie_Carver haha love it! thank you! It was a great start today, looking forward to meeting & working w/ everyone!! :D," the new Teen Wolf actress tweeted back to the welcoming cast.

Cho's character will reportedly be of Korean and Japanese decent, according to E! Online, a description that ties in with the Asian theme executive producer Jeff Davis hinted at for season 3B.

"We're heading into a new mythology based on the Kitsune myth, which some people might know a little bit about," Davis said at the show's recent Comic-Con panel. "It is a very, very fascinating Japanese shapeshifter myth about the were-fox and the trickster spirit."

Will Cho be the Kitsune? Could the were-fox/trickster become the new big bad for the second half of season 3?

Fans can find out when Teen Wolf picks up again in January on MTV.
