Hanna's (Ashley Benson) mom may have told her (over and over) to let her lies go, but Hanna won't stop until she knows her mom is safe, as we can see in this sneak peek of Pretty Little Liars Season 4, Episode 5: “Gamma Zeta Die.”

In this clip from the episode, Hanna goes looking for her mom's muddy Manolos. We know Ashley already dumped them, but Hanna worries "A" has made off with the incriminating evidence. Then when she tries to check her mom's closet for them she realizes Ashley has locked it, which is apparently a first. Unsurprisingly, that doesn't inspire confidence in her mom's story.

Here's the official synopsis of the episode:

Spencer and Emily make plans to visit a nearby college, but they have very different agendas for their time spent on campus. Spencer's singular focus in figuring out Ali's apparent connection to the school contradicts Emily's real fears about her plans for after she graduates. And after a stinging attack by "A," Aria and her brother Mike don't see eye to eye regarding what's best for their parents.
