Lucy Hale Is 'Coming Undone' in 'Pretty Little Liars' Tonight

Lucy Hale makes a startling discovery in this new still from Pretty Little Liars.

In tonight’s episode “She’s Come Undone”, Emily (Shay Mitchell), Hanna (Ashley Benson) and Spencer (Troian Bellisario) are concerned for Aria (Hale) as they watch their friend crumble after learning shocking news about Ezra (Ian Harding). Not knowing what is true or what to trust, Aria goes looking for answers, not wanting to believe this revelation to be true.

While concerned for Aria, Spencer is not doing so well herself. Trying to prove to her parents and Toby that she can kick the habit on her own, Spencer has to be careful because one misstep could send her to rehab. But can Spencer really rein it in, or will her constant curiosity and drive be her undoing?

Meanwhile, Paige (Lindsey Shaw) has had enough with Emily’s secrets and is determined to stop it.

“She’s Come Undone” airs TONIGHT @ 8PM ET/PT on ABC Family. 10+ pics inside…
