It is time for Aria to come undone in "Pretty Little Liars" season 4, episode 21. After Ezra's shocking revelations, this instalment of the show sees Aria's life falling apart. In the sneak peeks, she is clearly flipping out and wants to go face-to-face with Ezra.

Aria Ransack Ezra's Apartment and Runs Away

Spencer finds the notes only when Aria breaks into Ezra's apartment and turns the place upside down.

"He thinks one of us did it," says Aria and the other Liars listen to her.

It is clear that fans are not going to know about the killer of Alison or who is A, however, only Ezra can tell the Liars about these queries. While ransacking the apartment, Aria finds notes and the Grunwald tape that states that Alison is still alive.

During Aria's mission, Ezra is not at home as he is busy at Random House (the book publisher) to take forward the true crime novel about Alison.

At the end of "Pretty Little Liars" season 4, episode 21, Aria runs away which is sad because Spencer needs her during this time.

Meanwhile, Hanna meets Travis at the locker. He tells her that he cannot talk right now because he is going to the court with his dad. His dad is in trouble with the cops over Wilden.

Emily finds Spencer in the courtyard and tells that she has to do an urgent money drop for Ali who needs cash. While they are talking, they see Aria walking in the school in order to confront Ezra. However, he is taking time off because of a family emergency.

Paige meets Emily, and she wants to hang out with her. Paige sees a lot of cash in Emily's bag and questions her. However, Emily covers up and tells her that it is for her grandmother.

Hanna wants detective Holbrook to let Travis' dad, but he is not ready to listen. Later, Hanna meets Travis who tells her that Holbrook defended his dad, and now he is going for probation and community service only.

Spencer finds a bottle of pills in her locker from A. Emily says that she can take them, but Spencer wants to throw them away herself.

The episode ends with A reading Ezra's manuscript. Later, A opens the fireplace only to burn the pages.
