Merritt Patterson Is 'Ravenswood''s Newest Resident

Merritt Patterson"Ravenswood" is quickly becoming the hottest zip code in the state of Pennsylvania. The "Pretty Little Liars" spin-off has added yet another cast member: "Kyle XY" actress Merritt Patterson.

According to The Hollywood Reporter, Merritt will play Tess, former best friend to Olivia (played by Elizabeth Whitson), who as luck would have it, is not part of the curse around which the series' plot centers. She'll make her debut in the premiere episode airing after the "Pretty Little Liars" Halloween special.

The actress, whose past projects include "Supernatural," "Life Unexpected" and "Percy Jackson & the Olympians: The Lightning Thief" (for which she was awesomely though vaguely credited as "Pretty Girl #2"), joins previously cast stars Tyler Blackburn—whose "PLL" character will make the move from Rosewood to Ravenswood—in addition to Brett Dier and Elizabeth, who will play twins Abel and Olivia.

"Ravenswood" follows five strangers linked by an ancient, deadly curse. They must uncover the mysteries of their town before it's too late...for everyone.
