Pretty Little Liars Season 3 Cast Promotional Pictures

In all-new episodes of ABC Family’s hit original series “Pretty Little Liars,” returning on, Tuesday, January 8th, 8:00PM – 9:00PM ET/PT, 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.
