As Matthew Buchanan's drug story line about to kick into high gear, One Life To Live has cast a pair of new characters to interact with troubled teen.

First up? Jack Rovello. The young actor will play Justin, a teen that tempts Matthew to head down a long and dangerous path. After introducing himself to Nora and Bo, Justin makes Matthew an offer he can't refuse. Uh-oh.

Also, Broadway veteran Charlotte D'Amboise (pictured) has been cast on the show. Look for the actress to appear as Llanview High's new principal Ms. Dickinson. She debuts on January 9.
