Pretty Little Liars returns to the ABC family tonight with a new episode called, “Mona-Mania!” On last week’s show Radley Sanitarium gaveMona a clean bill of health and she was 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 took very different views of the “new” Mona. Did you watch last week’s show? We did and we recapped it here for you!

On tonight’s show Aria, Emily, Hanna and Spencer are sure that Mona is up to her old tricks again, but can they prove it? Hanna, still holding out hope for her former friend, is not so sure. With Mona seemingly popping up everywhere, it sure seems like she has a plan. But with no real evidence to prove Mona is back to her evil ways, how can the Liars prove what they believe to be true? Meanwhile, Aria’s fears about her father grow stronger when something vital that is hidden in her room goes missing.

Tonight’s episode looks like it is going to be great and you won’t want to miss it, so be sure to tune in for our live coverage of ABC’s Family ‘s Pretty Little Liars at 8:00 PM EST!
