John "Junk" Moretti was a Tree Hill High Student, of Italian descent, who played basketball with Lucas on the River Court before he joined the Ravens. After he graduated, Junk bought a house with his old friends Mouth, Fergie, Skills and, later, Millicent where they maintained their fun, if not slightly childish, lifestyle.
