The first confirmed resident of ABC Family‘s Ravenswood is bad boy Caleb Rivers. Pretty Little Liars co-star Tyler Blackburn will be joining the series’ upcoming spinoff. The series hails from the same auspices as Pretty Little Liars: Warner Horizon, Alloy and executive producers Marlene King, Oliver Goldstick and Joseph Dougherty. The new series takes place in Ravenswood, a town near Liars‘ hometown of Rosewood PA, and revolves around five strangers who are connected by the curse that has plagued Ravenswood for generations. Caleb (Blackburn) will travel to Ravenswood in the third annual Liars Halloween special in October, which will be used to introduce Ravenswood and its inhabitants and launch the new series. Blackburn, repped by Gersh and James Feldman & Cynthia Farrelly Gesner, has been a PLL fan favorite. He has been on the hit drama since the end of the first season, upped to a regular after Season 2. He will appear in every episode of PLL‘s upcoming fourth season this summer before segueing to Ravenswood.
