context: Daniel Robert Scott, also known as Dan/Danny, played by Paul Johansson as a series regular from the pilot to the thirteenth episode of season seven. He appeared as a special guest star for two episodes in season eight. He returns in season 9 until he is killed. Daniel Robert "Dan" Scott is the original villain in Tree Hill. Dan is the ex-husband of Deb Lee and the father of Nathan and Lucas Scott. Originally wanting nothing to do with Lucas, he begins to want a part in Lucas's life. We find out that not only has Dan been following Lucas all his life, but that he wanted joint custody of Lucas but Karen refused. Lucas later moves in with Dan after learning that he has Dan's heart condition as it's the only way he could afford the medication. When Lucas fails Dan's test, he takes away Lucas's college fund which he had started when Lucas was a baby. He hired a woman (Jules) to make Keith fall in love with her as revenge for sleeping with Deb. Jules actually falls in love with Keith but leaves him on the altar after being threatened by Karen. Deb attempts to murder Dan by burning down his dealership. Dan, thinking it was Keith, shoots Keith and lets Jimmy Edwards take the blame as Jimmy committed suicide. Lucas gradually accepts Dan as his dad until he finds out what he did to Keith. Dan, realizing Nathan will never forgive him, turns himself in to the police.
