Pretty Little Liars did not deliver the most compelling hour of television with last week's "Turn of the Shoe."

But the episode did set up a number of conflicts for the rest of Season 4, starting with Hanna wondering about her mother's secrets and why she's been lying for so long. Watch mother confront daughter in this clip from tomorrow night's "Cat's Cradle."

Elsewhere, a clue in Ali's things will lead the girls to a very creepy mask maker (as if any other kind could exist on this show, right?), as teased in the following sneak peek:

And, finally, Spencer will confront her sister with a few questions and suspicions. Does Melissa know more than she's letting on? Watch now and return to TV Fanatic tomorrow for a detailed review of the latest Pretty Little Liars Season 4 episode:
