Lock your doors! Charles DiLaurentis is on the loose and ready to stir up some trouble after the events that occurred in episode 7 of "Pretty Little Liars" at the abandoned arcade. Now the secret about the mysterious DiLaurentis sibling is out in episode 8.

Thanks to some drug-laced gummy bear candy that Toby (Keegan Allen) accidentally ate, the exchange with Charles didn’t go as planned. Now the Rosewood police and the entire town know about the “psycho stalker” – which is good and bad. With the news being out in the open, everyone can be on alert. However, the Rosewood police aren’t exactly known to be the cleanest or most competent cops. And this also means that the Liars will lose whatever freedom they had regained after escaping the Dollhouse.

Last week viewers learned that Aria (Lucy Hale) was a finalist in an art competition for her photography. But the synopsis for episode 8 teases that she might not even be able to enjoy seeing her work on display in an art gallery. Ella (Holly Marie Combs) is “determined to keep her safe,” and that means staying at home.

Elsewhere, Hanna (Ashley Benson) is stressing about the scholarship money she received from the Carissimmi Group. The company is somehow connected to Radley and the DiLaurentis family, but Hanna’s not sure what that means for her. Ashley (Laura Leighton) already cashed it – but that’s not going to stop Hanna from hatching a plan to return it. Unfortunately that decision means “ruining her chances at going to the school of her choice.”

Alison (Sasha Pieterse) will have a different situation on her hands. The teen learns more about her mysterious older brother, but finds it hard to “connect a deranged murderer” to the childhood photos and memories she has of Charlie. Could she be onto something?

Finally, prom is in jeopardy for the Liars as the high school considers banning the girls for security reasons. Will the girls miss the biggest dance of their high school careers?
