According to the preview, the four Rosewood girls are 'closer than ever' to knowing the truth about Alison and the person who killed her.
"Pretty Little Liars" gasp when watching a footage that reveals who the guy last seen with Alison is. In "Know Your Frenemies", Spencer must now handle the return of happy newlyweds Melissa and Ian, even though her suspicions of Ian's ties to Alison grow.
Meanwhile, relationships are in flux in Rosewood, PA as the Liars face many obstacles. As Noel steps up his pursuit of Ezra and what he can gain from his knowledge, Aria and Ezra start to feel like there may be no way out. Emily must also deal with opposition to her love life, as her mother Pam's perceived tolerance of Maya comes to a screeching halt.
But with the other girls' support and unexpected help form an unlikely source, the future for the Liars doesn't look so hopeless. Meanwhile, "A" has Hanna jumping through old habit hoops with regard to the stolen money. Will Hanna fall back into her old ways, or does she have the will power to stand up to "A" and her games?
The episode airs Monday, January 17 on ABC Family. During TCA Press Tour, the network announced that the show is coming back for season 2.
