It's not about the lies, Spencer says.
It's about the poor girl who was buried in Ali's grave.
While A has returned and we're still uncertain whether or not Mona is working with A or they're playing on the same side for different teams, the Liars have a more important mystery to solve.
The girls tried to find the identity of the girl as soon as they learned Ali was alive. Now that they know it was Bethany Young who took Ali's place, they're going to great lengths in Pretty Little Liars Season 5 Episode 7 to find out why the unfortunate girl from Radley was chosen.
Adding to the excitement? Caleb is going to have his first run in with Ali, but I'm willing to bet Ali will be the one to walk away with her head spinning.
