Aside from their love for hoops, Lucas and Nathan seemed to have little in common. But the two young men are bound by the fact that they share the same father. As Nathan is increasingly brought into the world Lucas knew before he joined the high school team, the two boys begin acting like brothers, not enemies, for the first time. Years in the making, a deep and bitter conflict had slowly unfolded as the two boys struggled to come to terms with a father who chose to live vicariously through one son while ignoring the existence of the other. Now, Nathan and Lucas have formed a unique bond based on mutual resentment of their father. Meanwhile, the girls of Tree Hill explore their own interests beyond romantic entanglements.
