This page is dedicated to everything related to Pretty Little Liars. It can be quite hard trying to find all the clues in the episodes and come up with theories that work. Here's the place to do it. Feel free to reply, reblog or submit your Pretty Little Liars questions to me.
Ali tells Spencer that she saw her go back to the barn and fall asleep. She tells the girls that all of them were asleep when she left the barn that second time.
But when she is taking the lie detector test, she says that the last time she saw Spencer was when she dropped her medicine after coming to her house.
So did she figure out how to pass a lie detector test? or did she lie about seeing all of the girls sleeping?
