Pretty Little Liars - 'A' Attacks Emily At Rosewood High - "Bite Your Tongue" (4x17)

While working late at school Emily hears noises. She calls out but nobody answers. The door to the classroom closes and some loud music metal music starts coming through the PA. The lights start flashing and she calls her father to come get her. She sees shadows of someone moving in the hallway and a sign flashes "Act normal, bitch." Hanna wakes up on the chair. There is blood on her mouth. The pages she stole are all gone! Emily sees her father pull up but can't open the window. Wayne finds the door closed. A shadowy figure tries to get into the classroom. She breaks a window and yells for her father to help her. Wayne climbs up the side of the building, opens the window and gets her out. The person, wearing a dark hood, gets into just after they reach the ground. Suddenly Wayne collapses. An ambulance arrives to take Wayne to the hospital. He tells Emily he's had some tests done and there are issues with his heart.

Hanna's new interest in crime novels helps her to come up with a plan to try and figure out whose body is in Alison's grave. While Hanna is on her hunt, Spencer is working overtime to decipher the stories in Ali's diary which she hopes will reveal the identity of Ali's mystery man, but with both girls hot on the trail, will their work lead them straight into the path of "A"? Meanwhile, Aria is upset with the new friend Mike has made and Emily's dad is concerned about her behavior. #PLL #PrettyLittleLiars
