'Pretty Little Liars' Season 7 Finale: AD Has Twin Sister?

Ahead of the final ever episode, showrunner Marlene King is dropping some pretty huge hints about how the show will end and it's safe to say that things are going to get pretty insane. But, we think there's probably a show for you among the five.

Let's get ready for tonight's finale by taking a look back at some of the show's most gruesome deaths (above)!

Now, as Mitchell and her longtime cast mates prepare for the series finale to air Tuesday night, she is reflecting on what she learned from being Emily. However, the finale plays out like a movie that has a "different" and "special" feel to it as A.D. identity is finally revealed. Marlene did, however, tell the actor playing A.D. that they were A.D. once she knew.

Though she didn't give too much away about the final scene, Marlene then teased that the world of PLL will continue, which means it can't all end it total disaster.

And though King has said she and the writers have known how they were going to end the show for two years now, they've kept tonight's series finale a heavily guarded secret. The mythology of this town will always go on.

The wait is finally over to find out the true identity of A.D. on Pretty Little Liars.

This Tuesday, Freeform (formerly ABC Family) will take viewers to the fictional town of Rosewood one last time as the network's hit series Pretty Little Liars wraps up its insane, twisted and always unpredictable seven-season run.

Fans have been eager to unlock the mystery behind AD for seven "Pretty Little Liars" seasons.
