We’re only a few days away from the Pretty Little Liars special Halloween episode. Sasha Pieterse, who plays Alison on the show, was recently interviewed about the episode and (lucky for us!) she gave away some great details.

PrettyLittleLiars.com reports:

Does A target Alison just as much as the Liars or does he/she target her even more?
Sasha: That’s interesting because we don’t really know how far back A has been doing all this stuff yet. We kind of find out in the Halloween episode…sort of. But A definitely puts pressure on the girls–a lot of pressure–and I think it’s in a different way.

There’s a lot of tension between Alison and Jenna. Can we expect a dance-off between them at the Halloween party?
Sasha: It’s not really a dance-off….it’s more of a stand-off! Their encounters—and there’s a few of them—get pretty hairy. It’s the first time Alison’s really been challenged and she’s like ‘WHOA! That’s not going to happen’. This is before “The Jenna Thing” and before a lot of things. At this point she’s the queen bee of the school and has it all so for someone to stand up to her it’s like ‘Who do you think you are?’

The Halloween episode is titled “The First Secret.” Will the secret be juicy and will it help viewers understand Alison and A better?
Sasha: It’s called “The First Secret” for many reasons. I think there is more than one juicy secret. For all the girls, their first secret revolves around Alison. It may be separately it may be together, we’re not quite sure. But it’s also the first encounter with the enemy. There’s also a really BIG first. I think [the episode] was cleverly titled and is very memorable.

So, after the Halloween episode, will viewers be able to narrow down the list of A suspects?
Sasha: Definitely…but I think you will be getting a new suspect as well. Of course there are a few people who have been suspects already but you don’t know if they are or aren’t anymore. Take Jenna [for instance]. [In the prequel] you see the first introduction of Jenna—you’ve never really understood why Alison disliked her so much and now you will.

The Halloween episode will air on ABC Family on October 19th.
