Pretty Little Liars star Janel Parrish will soon appear on your screen on CBS’ Hawaii Five-O.

As reported by The Hollywood Reporter, Parrish will appear in an upcoming season 3 episode of the CBS show playing an ambitious, determined chemistry student who wants to pursue medicine. Her character gets angry when something seems to interfere with her plans. The show is set and filmed in Honolulu, Hawaii, which is conveniently where Parrish was born and raised.

Fear not Pretty Little Liars fans, Parrish is still a series regular on the ABC Family show, playing the maniacal Mona Vanderwall. In fact, the first episode of the second half of the third season is entitled “She’s Better Now.”

As mentioned earlier by Hypable, the episode will focus on Mona and her sanity once more. “Radley Sanitarium has given Mona a clean bill of health and she is headed back to the halls of Rosewood High, much to the Liars’ dismay. With their former tormentor now back in their everyday life, Aria, Emily, Hanna and Spencer take very different views of the ‘new’ Mona. Sure she made their lives a living hell, but is she really cured? And what other secrets could she be holding onto? It is up to Mona to prove to the Liars if she has changed or not.”

The 24-year-old actress has previously appeared in Heroes, The O.C. and Zoey 101 among other television and film credits.

Pretty Little Liars returns on January 8 at 8 p.m. EST on ABC Family.
