In the mid-season premiere of “Pretty Little Liars,” entitled “She’s Better Now,” airing at 7 p.m. Tuesday, Jan. 8th, 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. She made their lives a living hell… Is she really cured? And what other secrets could she be holding onto? It’s up to Mona to prove to the Liars if she has changed or not.

The “lies” continue in the Season Two premiere of “The Lying Game,” entitled “The Revengers,” airing at 8 p.m. Tuesday, January 8th. Alec is in jail following his arrest for Derek’s murder, but he still manages to unnerve Emma, who is desperate for answers.

Meanwhile, Mads goes looking for trouble, and meets a mysterious new guy in town.
