Jack Hess who has a master's degree in education and who taught six years at boarding schools, is the new Dean of Discipline at Harbor High and is responsible for the measures to be taken after the gunshot incident. He wishes to punish Marissa Cooper but is only able to expel her. When Ryan Atwood punches him in the face, Jack uses that to have expelled Ryan as well. He then gives Seth Cohen two months detention when he and Summer Roberts steal a tiki hut, which was a prop in a school play, so Ryan and Marissa can have sex in the hut on the beach. He is also responsible for Summer losing the social chair to Taylor Townsend by tricking her to admit that she stole a theatrical set. At the Summer Dance, Summer sees Taylor and Jack sharing an intimate tryst and Sandy uses the information to blackmail Jack into leaving Harbor to save his career and get Ryan back into Harbor.
