‘Pretty Little Liars’ Spoiler: Alison Is Probably Alive! Girls Will Know In The Halloween Special Episode

There is certainly another reason for Halloween to be extra memorable especially for those who are yearning for revelations.

Fans of the mystery thriller 'Pretty Little Liars' still cannot get over from the summer finale after the revelation that 'A' is no other than Ezra. Nonetheless, the drama is still not over because ABC Family has hinted about Alison's existence.

"The Liars always thought their friend was dead. This October, the search for Alison is on," says the voiceover in the latest promotional video of the series.

In the Halloween special episode entitled 'Grave New World', Spencer, Aria, Emily, and Hanna are determined to find Alison before Ezra does. Clad in timely Edwardian costumes, the girls will end up in a creepy cemetery party.  Viewers will have the chance to finally see Alison in the flesh if she's really still alive.

Caleb will similarly go to Ravenswood to help the girls with their mission. He will meet Miranda whose role in the community is yet to be revealed.

The episode might similarly explain Ezra's reason for stalking the girls.

'Grave New World' will air on October 22 at 8 p.m..
