Pretty Little Liars fans, you might want to go back and watch a season four episode.

Why? Because it actually gives away A's identity! While one of TV's most infamous tormentors was finally unmasked in the ABC Family hit's midseason finale on Tuesday night, showrunner Marlene King told E! News that (Spoiler Alert!) Cece Drake (Vanessa Ray) was first revealed as A in the episode "Crash and Burn, Girl!"

The episode, which aired on July 23, 2013, dealt with the fallout from the crash in the season three finale, with King explaining, "It's after the big fire at the lodge and they think they see Ali and someone flew in that plane—and now we know it was Sara Harvey—but we literally say in an episode that the plane was rented by Cece Drake."

Yep, that was actually the first reveal of A's identity!
