"We all know what you did," Emily confronts Ian after finding out who the last person Alison was seen with. In the next "Pretty Little Liars", the Rosewood High dance-a-thon brings about surprises and suspicions for the Liars. As the school gets ready for the dance-a-thon, Aria, Emily, Hanna and Spencer have more on their minds than raising money for the school trip to Washington, DC.
Hanna is having a hard time finding a job to help her family's financial situation, but when "A" has a job for her, will Hanna be able to refuse? Emily can only think of Maya and is desperate to speak to her - so much so that she enlists the help of Caleb, the new bad boy in the school.
And as an important piece of property goes missing, Spencer finds being in close quarters with her new brother-in-law, Ian, more difficult than ever. Meanwhile, Aria's former babysitter, Simone, comes back to town for a surprise visit. But what should be a happy reunion quickly becomes a nightmare for Aria when Simone sets her sights on Ezra.
"Veronica Mars" alum Alona Tal plays Simone who is introduced to Ezra through Aria's mom, Ella. "I interact with [Ella] a bit, especially in recent episodes," Ian Harding who plays Ezra said. "We've had similar storylines where we intersect. She introduces me to [Simone], who becomes another complication."
"Careful What U Wish 4" airs Monday, January 24 on ABC Family.
