The truth is out on Pretty Little Liars, but what will the consequences be on Season 4, Episode 21 (“She's Come Undone”)? The title alone is enough to tell us that Aria does not have an easy time absorbing the revelation that her love is kinda totally a stalker, and the sneak peeks of the episode just make us more concerned for the heartbroken Liar.

We've examined the sneak peeks closely to see what they reveal. Here's what we've learned.

1. Aria wants answers. In this sneak peek, we see Aria barreling through the halls of Rosewood, declaring that she needs to speak to Ezra face-to-face. "I don't know where the truth begins and the lies end," she explains to her worried friends. Has she discovered something else that makes her even madder than she had been?

2. And she's not thinking clearly. We love angry Aria, but the girl is obviously not thinking clearly. In the second half of that clip she bursts into Ezra's class and, seeing that a sub has taken his place, demands, "Where's Ezra?" Um, don't call your teacher by his first name, Aria.

3. Ezra is taking time off. The sub explains that Ezra took time off for a "family emergency." We're with Aria on this one: "Oh, a family emergency," she says sarcastically. "Right."

4. Ezra's journals reveal a lot. In a sneak peek that you can watch here, Aria breaks into Ezra's apartment — and discovers a journal overflowing with details about the Liars' lives that go back to Season 1. No wonder she flips out and rips his apartment apart.

5. Spencer's parents want her to head to rehab. In this sneak peek, we see that the Hastings have decided how Spencer should deal with her drug problem — rehab.

6. Spencer wants to make a deal. Spencer begs her parents to give her "one chance to get off [the pills] on her own." But will she actually be able to do it?

7. Travis is back! Meanwhile, in this sneak peek, sexy Travis returns, and Hanna tries to apologize for that time they made out when she was clearly not ready to move on from Caleb.

8. And he's headed to court. More interestingly, Travis says at the end of this clip that he's about to head to court. Does he have new info for Hanna?
