In 'To Kill a Mocking Girl', old and new relationships are examined as the girls try to pay tribute to Alison's memory.
The saying "The past will come back to haunt you" is never more true than for Aria, Spencer, Hanna and Emily. In the next "Pretty Little Liars", as the girls try to pay tribute to Alison's memory, the four friends are faced with unresolved issues.
Aria has an unsettling encounter with her father's former mistress, Meredith. Emily is forced to see Toby Cavanaugh in a new light. Spencer is reeling in the wake of a vengeful Melissa. And Hanna is desperate to have her boyfriend, Sean, forget the "old" Hanna. Meanwhile, Detective Wilden uses his new connection to Hanna and Ashley to his benefit.
"To Kill a Mocking Girl" airs on June 22. Beside the preview, several clips have been released to show how Aria has an awkward meeting with her dad's former mistress, Emily invites Mona to join her and Ben, Hanna considers to lose her virginity, and Spencer deals with her angry sister.
