Ravenswood has another resident! The Pretty Little Liars spin-off has added another fresh face to their cast: Merritt Patterson (previously seen on Supernatural and Kyle XY). According the The Hollywood Reporter, Merritt will play Tess, former best friend to Olivia (one of the three main characters first announced) in the show about a Pennsylvanian town suffering from a generations-long curse.

Merritt joins cast headliner Tyler Blackburn (PLL’s Caleb), who will be making the jump from PLL to Ravenswood following the former’s Halloween special. Other roles already cast include series twins Olivia (Elizabeth Whitson) and Abel (Brett Dier). Still yet to be cast is the role of Miranda, the third in the Ravenswood trio that will appear in the PLL Halloween episode.

Ravenswood will premiere in October, and will follow the lives of five strangers who, connected by the curse, will investigate the town’s history before it is too late. Merritt will be a series regular, but Tess will not be one of the characters involved with the curse. That’s probably a good thing, right?

We wonder if Tess will be a mean girl in the show. We know that Olivia is a former prom queen character who has experienced a fall from grace. Could former best friend Tess have pushed her?

Are you excited to see Merritt cast in Ravenswood? What do you think her character will be like? Let us know in the comments below!

Pretty Little Liars Season 4 premieres on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
