The girls are all having a hard time. As the official synopsis explains, "It is a rough time for all of the Liars as Spencer is reeling about the memories from her 'lost summer,' Aria is still nursing a broken heart, Emily is reeling from Paige’s betrayal and Hanna unsuccessfully attempts to wade back into the dating pool."

Hanna tries to wade into the dating pool again? Does that mean more scenes with Travis? Their first date got mighty awkward when Hanna got distracted by Mrs. D with the cops, but maybe he's willing to give her a second chance.

As for Emily and Paige, based on this sneak peek, Em is not planning on forgiving Paige any time soon. Will Paige be able to convince her girlfriend that she really was acting out of love and concern, not malice?

Finding out more about Mrs. D. After last week, Ali's mom is the new "A" suspect numero uno, and the Liars aren't letting their personal problems prevent them from trying to find out what Mrs. D is really up to. As the official synopsis goes on to explain, "As each girl tries to deal with her individual issues, they must focus their attention on their suspicions surrounding Mrs. DiLaurentis. Assuming that Mrs. D knows more about Ali and the night she went missing, girls decide to help out at her charity bridal fashion show to gain access to the DiLaurentis house to search for answers."

Well, that explains why all the Liars are wearing wedding gowns in the sneak peek photos. But what about this sneak peek of Spencer running around in the dark in her dress. Does her search for clue go wrong?

Ashley Marin gets her sneak on. Speaking of Mrs. D being suspicious, in this clip Ashley Marin goes sneaking around in the DiLaurentis house, and finds a bag of Ali-sized clothing that was bought just yesterday. Does Mrs. D know Ali's alive?
