I confessed at our Boston book signings the truth about Pretty Little Liars, and it is that I HAVE NO IDEA WHAT IS HAPPENING on that show right now. NONE. What anyone’s motivations are and who is doing what and why don’t they just look for the person in town who appears to have the greatest amount of technological omnipresence and then whack that person over the head with a heavy object and see if the texts stop? The plot has gotten so inextricably twisted that I don’t know if they can untwist it without having an episode where Laura Leighton sits down in a wingback armchair and speaks directly to the camera for an hour to explain it all. At least everyone looks pretty.
