The Pretty Little Liars Season 4 summer season is quickly headed toward a conclusion, and as the stakes continue to rise, we get more and more anxious to know what happens next. Fortunately, the sneak peeks for Season 4, Episode 10: "The Mirror Has Three Faces" (August 13, 2013) give us a few clues about what's coming up in the episode.

Caleb is a busy boy. In this clip, we see that Caleb has been hard at work in his role of tech genius/detective.

A solid clue. This week, Caleb's powers are aimed at finding out more about that PO box in Philly. While he hasn't confirmed if the box belongs to CeCe, he has managed to track down a cable bill associated with the box, and that's connected to a physical address. Time to go a-spying?

Hanna wants Mona's help. In the clip below, Hanna asks Caleb to help her get into Radley, because she wants to know what info Mona has on CeCe.

Caleb is not amused. Caleb doesn't like this plan. At all. He knows "A" is still dangerous, and he thinks Mona is still the enemy, despite Hanna's insistence that her former foe has changed.

A bold proposal. In fact, Caleb has a revolutionary idea for Hanna: She should fess up about "A" being back to her parents and the cops. Hanna is not about that plan at all.  

Mona is in Radley for a psych eval. There was some confusion amongst fans about whether Mona's latest trip was voluntary or ordered by the police. The clip above clarifies that, with Caleb explaining that she was sent to Radley for a psych eval.

The return of Wren. In this final clip, Wren finally returns from Suspiciously MIA Land, just in time to run Mona's psych evaluation.

Mona is still full of snark. Whatever her motivation for turning herself in for Wilden's murder, one thing is for sure: Mona hasn't lost her signature snark.
