Season 4
As the end of High School approaches, everyone finds themselves at a crossroads in their lives. Nathan survives the accident and after some initial confusion, Haley is revealed to be pregnant while Rachel turns her attentions to Nathan after Cooper leaves town, using Nathan's theory that it was really Keith who saved him from the accident to get Nathan's attention.
Rachel backs off when she learns that Haley is pregnant and Nathan later learns that he had a vision of Keith and it was this vision that gave him the strength to get out of the water.
Shortly after finishing her friendship with Peyton, Brooke also breaks up with Lucas and then moves in with Rachel. Rachel sets Brooke up on a date with an older guy, Nick Chavez (guest star, Reynaldo Valentin), who turns out to be Brooke's new teacher.
After Brooke dumps Nick for cheating on her, Rachel informs Brooke that she is failing calculus and together, the two girls steal the calculus test from school but to cover their tracks, they are forced to join the "Clean Teens: Virgins for Life".
Newcomer Chase Adams (guest star, Stephen Colletti) also joins the Clean Teens and he and Brooke begin dating while Rachel is expelled for taking the fall for the stolen calculus test and later leaves Tree Hill with Mouth, who returns alone after she goes AWOL.
Skills Taylor becomes a Raven and Lucas is granted permission from Whitey to rejoin the team (as long as he keeps taking his heart medication and doesn't play for more than fifteen minutes per game).
In the run-up to the State Championship, Nathan borrows money from a loan shark, Daunte Jones (guest star, Rick Fox), who tells Nathan that the only way he can repay his debt is by shaving points in the semi-final and then by losing the State Championship.
When the Ravens actually end up winning, Daunte attempts to kill Nathan but instead hits Haley with his car and she is rushed to hospital along with Lucas, who had a heart attack because he didn't take his medication before the game.
While Lucas is unconscious, he has a vision of Keith, who shows Lucas how he has changed so many lives for the better and also tries to help Lucas remember what he saw on the day of the school shooting. Lucas wakes up with serious doubts about who killed Keith.
Meanwhile, Dan is in jail, covering for Nathan who beat Daunte to death in a rage for running Haley down. Daunte's autopsy results, however, show that he was killed in the car accident he had after hitting Haley, and not by the beating he was given so Dan is released and Nathan is overjoyed to learn that both Haley and the baby are going to be fine.
When Karen discovers that Dan was protecting Nathan all along, she starts to let Dan back in, realizing that he wants to be there for her and the baby. Deb, however, alienates everyone, including Karen, when her pill addiction resurfaces and she ends up overdosing.
To keep Deb on the straight and narrow, Nathan and Haley move in with her and throw a party on the night before prom where Mouth loses his virginity to Clean Teen Shelly Simon (guest star, Elisabeth Harnois), who runs out on him afterwards, and a tape from Nathan's past shows him having sex with Brooke after him and Peyton had called their relationship to an end.
Chase breaks up with Brooke because of this and Brooke's hopes of rekindling her friendship with Peyton are diminished.
When Brooke learns that Peyton isn't coming to prom, she goes looking for her and finds her tied up in the basement by her stalker, Ian Banks (guest star, Matt Barr), who terrorized her earlier in the season by posing as the half-brother she never knew she had, Derek Sommers (guest star, Ernest Waddell) and by sending her instant-messages under the username of "WATCHMEWATCHU".
The two girls defeat Ian together and restore their friendship in the process, moving into Nathan and Haley's old apartment together.
At prom, Lucas realises that a student named Abby Brown (guest star, Allison Scagliotti) witnessed Keith's murder and he confronts her about it - she tells him that Dan was the one who killed Keith, however Karen (having kissed Dan) refuses to believe Lucas.
Lucas steals Deb's gun and is about to shoot Dan when Karen collapses and is rushed to hospital with eclampsia. After an emergency C-section, Karen gives birth to a baby girl, Lily, though her own life hangs in the balance.
While Karen is battling for her life she has a dream where she sees Keith. She, Keith, and their daughter are in a garden looking at flowers and Keith tells Karen to go be with their daughter and says to Karen "look for me in the lily's".
When Karen wakes up she decides to call the baby Lily. Dan, meanwhile, turns himself in to the police.
Having finally gotten together, things are going well between Lucas and Peyton until she is offered an internship in Los Angeles.
Chase and Brooke get back together and Brooke owns up to stealing the calculus test, though is still allowed to graduate while Nathan also owns up to his point-shaving; Duke retract their scholarship offer but Whitey is offered a coaching job at a nearby college and convinces Nathan to come with him as his star player.
At graduation, Haley goes into labour during her valedictory speech.
In the season finale, Nathan and Haley become the proud parents of a baby boy named James Lucas Scott, choosing Lucas and Brooke as godparents, while Deb, in her role as the grandmother, seems to have finally found happiness.
Chase and Brooke consummate their relationship while Rachel returns to Tree Hill and throws a party for everyone. Mouth does something he's always wanted to do and kisses Brooke, while also making his peace with Shelly.
Karen takes Lily to Keith's grave and says they are going to visit him every day, while Dan's attempt to hang himself in prison fails.
Karen visits Dan (only to tell him that one day she'll have to explain to Lily that her father was killed by the brother he loved so much) but Lucas and Nathan both agree that they never want to see Dan again.
Lucas reveals that he will be Whitey's Assistant Coach at college and supports Peyton as she and Brooke prepare to go to LA together.
In the closing scene of the season, everyone heads to the River Court for a game of basketball; boys against the girls, followed by a one-on-one game between Lucas and Nathan, taking them back to the night Lucas became a Raven.
One Tree Hill was created by Mark Schwahn and is executive produced by Schwahn, Joe Davola, Greg Prange, Mike Tollin and Brian Robbins. One Tree Hill is a Mastermind Laboratories and Tollin/Robbins Production in association with Warner Bros. Television.
