Pretty Little Liars fans excited about Ravenswood may be less excited once they learn of a series regular departure for the new ABC Family.

Tyler Blackburn, who plays Caleb Rivers on Pretty Little Liars, will be the first new resident of Ravenswood. Caleb will travel to Ravenwood during the special Halloween episode of Pretty Little Liars where the new spinoff will be introduced. Blackburn will still appear in the second half of Pretty Little Liars’ third season, which airs June 2013. On Pretty Little Liars, Blackburn plays Hanna Marin’s (Ashley Benson) boyfriend, who has charmed his way into the hearts of many Pretty Little Liars fans.

It is unclear if Blackburn will return for Pretty Little Liars’ fourth season, as it presumably depends whether or not Ravenswood is a success. There has been no additional casting news from Ravenswood, although three character descriptions were put out earlier this month.

Ravenswood will continue Pretty Little Liars’ mystery thread by expanding its reach to a supernatural curse. “’Ravenswood’ will center on a town, not far from Rosewood, PA (the home base of ‘Pretty Little Liars’), which has suffered under a deadly curse for generations. Five strangers suddenly find themselves connected by this fatal curse and need to dig into the town’s mysterious and terrible history before it’s too late for each of them.”

Will you miss Blackburn on Pretty Little Liars? What do you think his contribution will be to Ravenswood?

Pretty Little Liars returns June 11 at 8 p.m. EST on ABC Family.
