Breaking the Code

S2 E21: Aria, Emily, Hanna and Spencer have been the target of "A's" games for awhile, leaving them emotionally cut off from their families and friends. But when a surprising new victim of "A" is revealed, the girls' tight-knit group may just get one person larger. But what motive could "A" have of targeting someone outside of Alison's group of besties? Meanwhile, Spencer runs from her family troubles right into Wren's (recurring guest star JULIAN MORRIS) arms, as Ezra's new opportunity could push him away from Aria.
