The Desert Wolf is finally going to make an appearance in 'Teen Wolf!'

TV Line has just reported that 'NCIS' star Marisol Nichols will be joining the 'Teen Wolf' cast as the mysterious and potentially deadly Desert Wolf, who also happens to be the mother of Malia Tate (Shelly Hennig).

The Desert Wolf's appearance in the show has previously been hinted upon when Malia had a flashback about her car accident and remembered that her birthmother was there. However, the reunion could be tense, given Malia's nature.

However, there is also a possibility that the Desert Wolf will appear as part of a flashback scene when Malia was much younger.

Marisol Nichols has appeared in several TV shows including 'Beverly Hills, 90210,' 'The Twilight Zone,' 'CSI: Crime Scene Investigation' and 'Law & Order: Special Victims Unit.' However, she is best remembered as Agent Nadia Yassir from the sixth season of '24.' Nichols' most recent TV appearance was in 'NCIS,' where she portrayed ATF Special Agent Zoe Keats.

Meanwhile, things are getting increasingly scary in the fifth season of 'Teen Wolf' as Kira (Arden Cho) struggles to keep her fox spirit in check. Fans are wondering it was really Kira who killed that girl in the latest season or if she was being set up.

"I kind of think she got set up," Arden Cho said of the scene. "But I don't know."

Although it is a possibility, fans think that Kira may have finally given in to her kitsune nature and completely became "the messenger of death." Arden Cho doesn't seem to think it is possible that Kira had used the katana to impale an unknown girl to the McCalls' kitchen table.

"That katana could be anyone's katana," Cho insisted. "I'm pretty sure it wasn't me...I didn't do it."

'Teen Wolf' airs Monday nights at 10pm on MTV.
