You find out Alison is alive in Pretty Little Liars in season 4, once the show moves from “maybe she survived” hints to an on-screen confirmation.

Quick Scoop

  • The first clear confirmation in-story comes in the season 4 summer finale, episode 4x12 “Now You See Me, Now You Don’t,” when Mrs. Grunwald tells the Liars that she pulled Alison out of the ground the night she disappeared and that Alison is still alive.
  • The visual reveal for viewers is in the season 4 Halloween episode, often listed as 4x13/4x14 “Grave New World,” when the girls follow Red Coat and she turns around, revealing she is Alison, alive.
  • From that point, promos and recaps openly talk about Alison being alive and a “whole new chapter” beginning with her return.

So, in short: you find out Alison is alive at the end of season 4’s run of episodes, with 4x12 giving the explanation and the Halloween special (“Grave New World”) giving the face-to-face reveal.
