Pretty Little Liars season 6 was the penultimate outing for the gripping teen mystery series, and it finally offered answers to the seasons-long mystery of the identity of "A". Premiering in 2010, the series follows a group of teen girls who investigate the mysterious disappearance of a close friend while also being tormented by an anonymous stalker. Noted for its over-the-top twists and turns, Pretty Little Liars kept fans on the hook for seven seasons during its original run, and the mystery only seemed to get thicker with each passing episode. Though season 6 presented closure of sorts, it was far from the end of the story.
