Episode 20 of “Pretty Little Liars” finally exposed Ezra -- but it wasn’t as satisfying as many fans thought it would be. Instead of being unveiled as “A,” Ezra instead revealed to Aria that his big secret was that he was writing a true crime story about Alison’s disappearance. Admitting to dating Alison in college and knowing who Aria was before developing a relationship with her -- all of Ezra’s lies were finally on the table -- and they completely devastated Aria.

Episode 21, “She’s Come Undone,” will find Aria dealing with Ezra’s betrayal … and thanks to some leaked spoilers, we know that it’s going to get very ugly. According to the synopsis for the Tues., Feb. 25, episode, the girls will begin to worry when Aria’s world starts to crumble. The teen will be looking for answers from Ezra, “not wanting to believe this revelation to be true.”

A sneak peek video reveals that she’ll take some time off from school in an attempt to get over Ezra’s shocking news, but her desire for the truth will lead her right to his classroom. “I need to speak to Ezra face-to-face,” Aria tells Spencer, Emily and Hanna. “I don’t know where the truth begins and the lies end.” Spencer argues that confronting him at school isn’t the best idea -- because of the whole “being in a relationship with your high school English teacher” situation -- but Aria doesn’t care. Busting into his full classroom, she’s shocked to find a substitute teacher inside. Demanding to know where Ezra is, the confused sub tells Aria that he took time off for a “family emergency.”

Aria’s confrontation in the classroom was a little suspicious, but photos from episode 21 show that she’ll really go off the deep end when a search through Ezra’s apartment ends in her trashing it. Will Aria’s actions go unnoticed by the school? Or will her romantic relationship with Ezra finally be exposed to school officials? “I’m not going to be the only one that suffers from this, Hanna,” Aria angrily tells her friend. “Ezra’s not just going to suffer,” Hanna argues. “He’s going to go to jail.”

Unfortunately Aria’s not the only one with some problems in episode 21. Spencer’s also dealing with her parent’s discovery that she’s been using prescription pills. This isn’t the first time that Spencer developed a problem with pills, and her parents want her to attend a rehab facility in Philly before the situation gets worse.

“I admit that I lost control but it’s not like last time,” Spencer says. “I’ve only been taking the pills for a few weeks.”

But when her parents refuse to budge, Spencer pulls out the big guns: college!

“I can’t have Radley and rehab on my record,” she argues. “All I’m asking is that you give me one chance to get off them on my own. Please.”

The synopsis for episode 21 sounds like her parents are willing to give her a shot, however “one misstep could send her to rehab.”
