Aria and the gang enjoy the 'American Idol' alum's performance of 'Cuckoo', before someone wearing a mask seemingly puts a drug into her drink.
An upcoming "Pretty Little Liars" Halloween-themed episode has been teased in some new clips. One of them gives an extended look at Adam Lambert's performance at a party which takes place in a moving train. Along with a band, the rocker sings "Cuckoo".
In the other snippet, the runner-up of "American Idol" season 8 greets Aria who sits alone while enjoying her drink. After the "For Your Entertainment" singer leaves her, a masked person walks by seemingly to put something in her drink without her noticing it.
Titled "This Is a Dark Ride", the upcoming Halloween special will air Tuesday, October 23 at 8/7c on ABC Family. Looking forward to some good old Halloween fun now that the traumatic events with Nate are behind them, Aria, Emily, Hanna and Spencer are in for much more than just some childish trick or treats once they aboard the Rosewood Ghost Train.
With "A" running amuck and unexpected party-goers popping up at every turn, this Halloween event becomes one killer party. The episode is also said to reveal a big moment about the night Alison went missing.
