S2, E24: As Aria, Emily, Hanna and Spencer search for the meaning of new clues, they are led to a doll hospital that holds some very familiar looking dolls and a little boy that knows more than he lets on. But what would bring Ali to such a creepy and weird location? And what can the four girls learn about the secrets that are stashed away on the shelves between forgotten playmates? Meanwhile, Jenna’s (recurring guest star Tammin Sursok) surgery brings about more than just the possibility of regaining her sight.
