And it looks like she'll be playing a ghostly character.
From the details we can see of the set, it looks like we'll be returning to Radley with Ziegler somehow involved in the story line. Perhaps via flashbacks that will finally tell us who Charles really is?
It could also be that Ziegler is someone else trapped in Charles' lair. Though the ratty beds scream Radley, the Liars really haven't explored their prison yet, except to try and escape.
Plus, we already discovered that Charles has a thing for recreating scenes, like the prom and the house with the videos of childhood. If he has a history with Radley, he might have recreated that scene as well. And it might be that Mona isn't the only girl they'll find trapped in the lair.
Either way, it's clear from the pictures that the show is also continuing on the dark path we glimpsed in the Season 5 finale, which felt like something out of The Twilight Zone.
Aside from haunting the halls of what could either be Radley or Charles' lair, Ziegler will also be dancing her way around the show in some capacity. And choreographer, Travis Wall, was on set to help her with the scene.
Pretty Little Liars Season 6 premieres June 2 on ABC Family.
