Pretty Little Liars stars Janel Parrish (Mona Vanderwall) and Yani Gellman (Garrett) give fans a preview of what to expect in Tuesday’s Halloween episode “This is a Dark Ride.”

The episode premiered for the cast at the Hollywood Forever Cemetery on October 16, adding to the already spooky themes of the episode.

As seen by an Entertainment Weekly clip of the Halloween episode, Garrett is ready to tell Spencer (Troian Bellisario) what he knows about Allison’s (Sasha Pieterse) death, but Toby (Keegan Allen) interrupts them and throws Garrett out. He eventually is able to tell Spencer what he knows towards the end of the episode, providing suspense and revealing good information.

Wetpaint recently interviewed Janel Parrish, who plays the first revealed member of the A Team Mona. During the summer mid-season finale, Mona was able to exit and enter the Radley institution without much difficulty, conspiring with Toby, and causing Pretty Little Liars’ fans to ask what else she will do.

For the Halloween episode that promises a character’s death, Parrish promised that viewers will be surprised at who dies, saying “It kind of comes out of nowhere.”

For those who want to see the development of the A partnership between Toby and Mona, Parrish says the upcoming season will fulfill this desire. “You will find out more about how they got together to work together, when, and what they’re doing. It will come more to light in the second half of Season 3.” Mona will be back at Rosewood High during the spring episode “She’s All Better Now.”

Pretty Little Liars’ Halloween episode “This is a Dark Ride” premieres October 23 at 8 pm on ABC Family.
