Wetpaint Entertainment: Can you tell us what the Halloween episode is about?

Oliver Goldstick: Well, the idea is all the PLL's are on the train as well as some other unexpected guests. And I'll just say it's not a ride that goes without event, and it has to almost come to a crashing halt because of the events on the train. And there's some incredible revelations. I don't want to give too much away. But aside from the fact that we have this wonderful metaphor of these great costumes, we have these incredible unmasking moments, and I think that's part of the joyride here. People can't jump off so easily. They're kind of trapped.

We heard it was amazing to film. That people actually got a little seasick.

Yeah. The cars were being shaken by crew members to give you that sense of back and forth. So I would imagine after six hours of shooting a scene, it could be vertiginous or nauseating.

Oliver also confirmed that we will be seeing both Sasha Pieterse (Alison DiLaurentis) and Jason DiLaurentis (Drew Van Acker) in the episode.

Catch the PLL Halloween special on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
