Brett Dier and Elizabeth Whitson have been cast as Abel and Olivia, twin teens who live in Ravenswood and whom the fans will meeting during the PLL Halloween episode that introduces the spin-off.
Dier has previously been seen on “The L.A. Complex,” but Whitson is a relative unknown so far.
Abel is a “lone wolf with an old soul” and Olivia is a “once carefree and happy spirit” who recently experienced a hardship. Not much else is known about the main characters so far, except that the show also features Miranda, a fiercely independent foster kid.
The spin-off revolves around the titular town, which has suffered under a deadly curse for generations. “Ravenswood” will at least be partially introduced before Halloween — Troian Bellisario just revealed Spencer and Toby are paying the town a visit this summer on “Pretty Little Liars,” which returns June 11 on ABC Family.
