Mona is reluctant to cooperate when asked about her emotional response, while Caleb is not impressed with Hanna's plan to visit Mona at Radley.
The next episode of "Pretty Little Liars" has got several sneak peeks ahead of its August 13 airing. In the upcoming "Mirror Has Three Faces", the Liars hit a breaking point with Hanna "willing to go to the enemy for help," but the game is changing and the discovery is shocking.
In addition to the usual promo, there are three clips that could give viewers further hints at what the Liars are facing in the next outing. One sees Mona having some kind of test at Radley Sanitarium. She is asked to tell her emotional response to a picture of one happy family, only to give a sarcastic answer.
The other two feature Hanna and Caleb in intense conversations. One of them shows Hanna asking Caleb to come with her to Radley to meet Mona, but he calls Hanna "desperate" for asking help from the enemy. Caleb suggests that Hanna go to cops and her parents instead and tell them that "A" is back.
