The lines between friend and enemy has been crossed on next week's all-new episode of Pretty Little Liars. And it looks like it's Emily who has to pay the price in Season 4, Episode 2 ("Turn of the Shoe").

So not only is Mona on "A's" hit list, but so is Emily! That image of her floating in the pool is going to haunt our dreams, not to mention that nasty bruise on her arm! "Turn of the Shoe" also marks the first appearance by Ryan Guzman, who play sexy self defense instructor. Now that she and Ezra are officially dunzo, we think it's safe to say that these two will definitely have a tryst. Sorry, Ezria fans! But what is it with Aria falling for her instructors all the time? It's kind of creepy. 

Here’s the official Season 4, Episode 2 synopsis

"A" makes a drastic move which leads to potentially devastating circumstances for Emily in "Turn of the Shoe." Mrs. DiLaurentis' presence in Rosewood continues to unnerve all those around her, especially when she gives Hanna a family parrot, whose gift for mimicry provides startling insight into Alison's last days. Tired of feeling defenseless against "A," Aria decides to learn self defense and is intrigued by her sexy instructor. Meanwhile, Toby shares a heartbreaking secret with Spencer, and Hanna makes an alarming discovery regarding her mom.   And to complicate matters even further, "A" nearly kills the newest PLL — Mona.
