Synopsis
After years of questions and mystery surrounding the night Alison DiLaurentis disappeared, her four best friends come face to face with Ali and finally learn why she disappered and what happened to her that September night.

Title and Background

 * Since Season 4 was dubbed as "the Season of Answers" this title definitely fits, since in finales we get alot of answers, and the title itself has "Answers" in it. We will expect A LOT of answers this finale that will probably lead in the mystery for Season 5.
