Chad Michael Murray as Lucas Scott
Lucas Scott is the son of Dan Scott and Karen Roe, and the nephew of Keith Scott; he has a younger half brother, Nathan Scott, on his father's side and a younger half-sister, Lily Roe Scott, on his mother's side (she is also his cousin through Keith). He was raised by his mother after his father abandoned them to marry Deb Lee, Nathan’s mother; uncle Keith, who always had feelings for Karen, took over the father figure role. Lucas grew up in Tree Hill, a small North Carolina town, along with his best friend and now sister-in-law Haley James. His fiance and the girl of his dreams is Peyton Sawyer. He is interested in literature and basketball.
At the beginning of season one, Lucas is recruited by coach Whitey Durham to play in the Ravens basketball team after most of the players are suspended for drunk-driving. He soon has troubles with his half-brother Nathan, who is also the Ravens captain, because Nathan wants to remain the star of the team and feels threatened by Lucas's arrival.  Encouraged by Dan, who also wants Lucas off the team, Nathan and his teammates make life difficult for Lucas, on one occasion kidnapping him and throwing him into a ditch. Nevertheless, Lucas is determined to stay on the team (although he removes the name "Scott" from his jersey). Lucas is also attracted to Peyton Sawyer (Nathan's girlfriend), who is disgusted by Nathan's behaviour towards his brother and breaks up with him. Nathan retaliates by pursuing Lucas's best friend Haley, who agrees to tutor Nathan in return for him leaving Lucas alone. Lucas and Peyton almost have a fling, but she halts it when Lucas reveals the depth of his feelings towards her, as Peyton doesn't want anything serious. Lucas then starts seeing Peyton's best friend Brooke Davis, causing Peyton to realize the mistake she has made. After a night spent in a motel together, Peyton kisses Lucas. For a while, they see each other behind Brooke's back. Haley finds out that Lucas is cheating on Brooke and this, along with the fact that Haley is seeing Nathan, causes a rift in her and Lucas's friendship. On the night that Peyton is about to tell Brooke about their relationship, Lucas and Keith are involved in a car accident; Keith had been drinking as he was nervous about seeing Karen who had gone to Italy for 6 weeks. Lucas is saved by Dan, who is present at the scene, and for the first time in the series calls Lucas his son, so that Lucas can get immediate treatment. Lucas wakes up from a short coma and makes up with Haley and to an extent Nathan. He breaks up with Brooke to be with Peyton, but Brooke discovers everything and ends her friendship with Peyton and Lucas. Lucas's feelings towards Dan are challenged when he learns that Dan wanted joint custody of Lucas, but Karen refused. He also finds himself in Dan's position when Brooke claims to be pregnant, although this turns out to be false. Feeling frustrated at not being able to play basketball due to his his injury, Lucas goes to a bar, where he meets Nicki and they have a one-night stand. When Peyton finds out about this, she rejects Lucas and renews her friendship with Brooke. Lucas's relationship with Nathan improves as Lucas realises that he got a better deal than Nathan who is damaged as a result of being raised by Dan. In the final game of the season, the Ravens are coached by Dan as Whitey is in hospital. The Ravens lose after Dan allows the still-injured Lucas to play. Afterwards Lucas and Nathan are united in standing up to Dan and Nathan too removes the "Scott" from his shirt. Wanting a fresh start, Lucas decides to leave town with Keith. Lucas and Nathan have a final conversation where Nathan calls Lucas his brother and Lucas says "I'll miss you, little brother". Before leaving with Keith he goes to say goodbye to Haley and discovers that she and Nathan have got married.
Lucas and Keith return to Tree Hill after Dan has a heart attack. Lucas tries to make up for his behaviour with Peyton and Brooke and becomes friends with both of them. He also starts seeing new girl Anna Taggaro, but they break up amicably when Anna is confused about her sexuality. Lucas realizes that he has romantic feelings for Brooke and begins to focus on building on a relationship with her, even though she is seeing Anna's brother Felix. Lucas discovers that he has inherited Dan's heart condition, but does not tell anyone except Dan. After discovering that Keith's new girlfriend Jules was actually hired by Dan to break Keith's heart, Lucas agrees to move in with Dan if he leaves Keith alone and pays for Lucas's heart medication. This sets Lucas at odds with his mother as she can't believe that Lucas would want to live with Dan rather than her. It also causes a new rift between Lucas and Nathan as Nathan feels that Lucas is replacing him and is bitter about Haley's departure to go on tour singing. Lucas and Karen are reconciled when she learns half of the reason he is staying with Dan, which is to protect Keith. This plan to protect his uncle fails when Jules leaves Keith at the altar and Keith leaves town after discovering that Lucas and Karen knew that she was hired by Dan.
Lucas discovers Deb's painkiller addiction and decides to avenge all of Dan's victims. He find a stash of cash and an incriminating ledger in the attic at Dan's dealership, and plans to expose Dan's illegal dealings, but ultimately fails as Dan has also incriminated Deb. Dan then reveals that the whole thing was a set up to test Lucas's loyalty, which Lucas failed. He loses Dan's college fund for him (which Dan had been saving since Lucas was a baby) and even his heart medication. Nathan also ends his friendship with Lucas after discovering that Lucas had planned to bring Dan down and visited Haley behind Nathan's back in an attempt to patch up her and Nathan's marriage. Lucas does however kiss Brooke in the season finale and confesses that he wants to be with her, but she still leaves for California to spend the summer with her parents. Ultimately, it is just Lucas and a broken hearted Peyton (after boyfriend Jake left her) for the summer. 
After the summer, Lucas remains at odds with Dan, who accuses Lucas of starting the fire at the dealership that nearly killed him. Dan tries to strangle Lucas on the basketball court, but Peyton, having learned the truth from Lucas, tells Dan that Lucas actually saved him from the fire. Lucas also protects the true arsonist: Deb. Lucas and Nathan continue to argue over Nathan's treatment of the returned Haley, and have a public fight after Lucas accuses Nathan of being just like Dan. Lucas struggles to pay for his heart medication and steals money from his mother, which Haley sees, forcing Lucas to tell her about his condition.
Lucas begins a non-exclusive relationship with Brooke and uses Rachel Gatina to make her jealous, but a series of events leads Brooke to sleep with Chris Keller, tearing them apart. Later, he forgives her after she gives him the 82 letters she wrote to him during her vacations and didn't send.
Keith returns and he and Karen finally get together and become engaged. Keith also plans to adopt Lucas. Tragedy strikes when Lucas's former friend Jimmy Edwards brings a gun to school and fires it, accidentally hitting Peyton and causing a lockdown. Lucas goes into the school to rescue Peyton, and they are confronted by Jimmy with the gun. Keith appears and persuades Jimmy to let Lucas and Peyton go. Jimmy then turns the gun on himself, not having meant to hurt anyone, but Dan, jealous of Keith's relationship with Karen and believing that Keith was the one who tried to kill him in the fire, shoots Keith dead, making it look as though Jimmy killed Keith and then himself.
Lucas is devastated by Keith's death and tears apart the flowers outside Jimmy's locker. However, he later attends Jimmy's funeral and comforts Jimmy's mother, knowing that it is what Keith would have wanted. Karen is also inconsolable and blames Lucas for going into the school. After seeing the effect of Keith's death on his mother, Lucas decides to finally tell Whitey, Nathan and Karen about his heart condition and quits basketball. He goes on a university tour with his mother and realises that he wants to become a writer. He is also Nathan's best man for his second wedding to Haley. He and Brooke break up for good during the wedding when Brooke learns that Lucas kissed Peyton during the school shooting.
Lucas tries to get Brooke back, but realizes it is not what she wants and maybe not what is meant to be. He saves Peyton from an internet stalker "Psycho Derek". He also helps Karen, who is pregnant with Keith's baby, and plans on going to the University of North Carolina when he graduates so that he can be close to home in case she needs him. Dan also helps Karen with her pregnancy, wanting to make amends for Keith's death. After talking with Dan, Karen persuades Whitey to let Lucas play 15 minutes a game, so as not to let him miss out on something he loves. Brooke and Lucas try again but realize they are over, prompting Peyton to confess her feelings for Lucas. Lucas then discovers that Nathan is planning to throw the state championship game because of his debts. Lucas plans to prevent this, and deliberately fails to take his heart medication in order to play better, but Nathan is inspired by learning that he's going to have a son and they win, with Lucas making the winning shot.
During the celebration, Lucas, after receiving Brooke's blessing, sees Peyton and tells her that she is the one he wants standing next to him when all his dreams come true. They become a couple at the after-party, but happiness is short-lived when Haley gets hit by a car and Lucas tries to tell the paramedics what happened, only to suffer a heart attack. As he is in the hospital, Lucas dreams that he is visited by Keith, who shows Lucas what life would have been like if he had been a lesser person. In the end, Lucas realizes that he has to go back to his life because he never told Peyton that he loves her. Lucas wakes up and begins a relationship with Peyton.
Thanks to an assignment, Lucas bonds with Glenda Farrell. He entrusts her the first draft of his novel. He begins to investigate Keith's death, as the Keith in his dream suggested that Jimmy didn't kill him, but he also starts getting closer to Dan, who tells Karen he wants a bigger part in Lucas's life. Lucas discovers the truth about Dan thanks to witness Abby Brown. He attacks Dan after walking in on him and Karen kissing, and tells Karen that Dan killed Keith, but Dan convinces Karen that Lucas is delusional and needs help. Lucas then steals Deb's gun and confronts Dan in front of Karen, having set him up by sending him a message from "Abby". Karen collapses and Lucas fires a warning shot at Dan, telling him not to touch her. Karen is rushed to hospital with eclampsia and has an emergency c-section. Lucas is given a half-sister, who is named Lily Roe Scott when Karen regains consciousness. Dan turns himself in for Keith's murder. Lucas graduates and gets as a reward his book (An Unkindness of Ravens) from his mother. That same day, he becomes an uncle with the birth of Nathan and Haley's son, James Lucas Scott, partly named after him. Lucas is named the godfather of James and announces that he will be assisting Whitey as Nathan's college basketball coach.
One year from Season 4 Lucas becomes the head coach of the Cobras, his college basketball team, and leads them to victory in the championships. Thinking about his future, he goes to see Peyton and asks her to marry him. She declines, feeling that it is too soon. As he is about to leave LA, his novel is picked up by a fresh new editor, Lindsey Strauss, and after about a year of editing, quickly becomes a bestseller. Soon after, he is scheduled to have a book signing in LA, where Peyton is living and working. Having missed her, he calls her and invites her to come to the signing. Peyton comes, but she witnesses Lindsey giving Lucas a congratulatory kiss, and assumes they are in a relationship and leaves thinking there is no hope for her and Lucas. Lucas thinks that Peyton did not bother to come, and consequently begins dating Lindsey.
Lucas suffers from writer's block and is under pressure from his editor and girlfriend, Lindsey. He also tries to help Haley with her son, Jamie. When Peyton comes back home, she reveals to him that she did come to the signing, and then inspires him by repeating his quote: "Your art matters". When he tells Peyton that the bartender she is flirting with at the Clothes Over Bros store opening is not good enough for her, it becomes obvious that despite his relationship with Lindsey, he still loves Peyton.
After remembering the night he proposed, he goes straight to her house. When Peyton begins to antagonize Lindsey, he goes to confront her, but things escalate into a verbal fight about the break up. A little bit later Peyton confesses her feelings kisses him, he kisses her back but later proposes to Lindsey, leading Peyton to tell him that she will bury her feelings so that he can be happy. He then wins his first game as the Ravens coach although all the girls miss it by getting locked in the library. He then has to go to Dan's parole and speak up in order to have him stay locked up. He decides to have Nathan as his best man and then fuses his bachelor party with Lindsey's, hoping he will get Nathan back together with Haley. He also gives Haley his new book and she tells him not to marry Lindsey after reading it. Lucas proceeds with the wedding, but Lindsey stops him after realizing his book is about Peyton. She leaves him and when he chases after her, he sees Lindsey's bags packed. After a confrontation, she leaves him, saying "People always leave, Luke. You know that."] Lucas flees to stay with his mother and Andy after the failed wedding. Andy convinces Lucas to go after Lindsey, he goes to her and tells her that one day she will come back to him. She comes back to Tree Hill for Jamie's 5th birthday and tells Lucas that it was really over. He then spends most of his time with Brooke, helping her cope with having baby Angie around after Lindsey calls him to tell him she is seeing someone, he blows up, eventually getting suspended from coaching ] He becomes heavily drunk and tells Peyton he hates her when she comes to his help. He later apologizes to her after being confronted by Haley and Lindsey comes by to tell him his book is over and he can e-mail her the dedication, when he does, she reveals by phone that she still loves him. He then decides to go to Vegas and calls someone to get married, the only question is whom, as the shot showed Lindsey, Peyton, and Brooke all answering their phones.
In the first episode of season six, the audience discovers that Peyton was on the receiving end of Lucas's phone call. He waits to see if she actually arrives, and moments later, he finds her through the crowd, making her way towards him with bags packed. The two share a kiss, Peyton glowing with happiness. The two board the plane on their way to Las Vegas.
When they get there, they spend the night in a kinky Vegas hotel room. The next day they go to the wedding chapel, however the tackiness of the place convinces them that this was the wrong decision. Instead, Peyton takes Lucas to the hotel room where he first proposed to her and they do it all over again, this time Peyton says "yes."
When Lucas is sleeping he is awakened by his cellphone, and is informed that Quentin Fields has been shot and killed. With the comfort of his friends and family, Lucas finds the strength to address his players and help them learn to cope with this loss.
With the upcoming release of his new book, Lucas travels to New York to meet with Lindsey. He tells Peyton that he wanted to tell Lindsey in person about their engagement. Once there, he is forced to tell Lindsey about his engagement when, during the meeting, he sees that a date in his book tour coincides with his wedding day. Lindsey is visibly upset and tells Lucas that she was right about he and Peyton all along and that he should have just told her over the phone.
Lucas starts his book tour which fails fast and is cancelled, so Lucas returns home to Peyton. Peyton reads an article in B. Davis Magazine that tells her that couples moving in together know less about each other than they think they do. Lucas and Peyton soon realize this and decide to lock themselves in the house until they are used to living with each other. They play fun little games with each other, like criticizing each other's choices in food and music, to putting a line of tape down the center of the house to split it into two. Eventually, the two decide to accept their differences since it is what makes them such an amazing couple. After the two resolve problems and fears of moving in together, Lucas is offered a movie deal by Julian Baker, who is, unbeknownst to Lucas, Peyton's ex-boyfriend. The film is to be shot in One Tree Hill, North Carolina.
|Peyton Elizabeth Sawyer|
Hilarie Burton as Peyton Sawyer
Peyton Elizabeth Sawyer is born to Elizabeth (Ellie) Harp and her boyfriend Mick Wolf. Soon after her birth, Peyton is adopted by a young couple, Larry and Anna Sawyer. However, her middle name comes from her biological mother. Anna Sawyer dies by running a red light on her way to pick Peyton up from school when Peyton is nine years old. Her father then decides never to bring up her real mother Ellie, but that does not keep Peyton from finding out that she was adopted when her biological mother shows up at the end of the second season. Peyton later finds out that she also has a half brother, by her father Mick Wolf.
Peyton is a beautiful, talented artist who portrays her emotions through her art. She keeps her heart guarded most of the time, for fear that if she lets anyone in close she will lose them like many others. She forged a friendship with Brooke Davis during the third grade and that friendship has continued over the years. She then joined the cheerleading squad for Brooke and they have shared their ups and downs together. Peyton drives a 1963 Mercury Comet Convertible in all five seasons which at times happens to be a major plot point as it was because of it that she met and first spoke to Lucas.
She is often inspirational for other people such as Stella (played by Andrea Bowen) with whom she felt a kinship (they were both artists with similar personalities) and helped reunite with her foster family in deleted scenes, or Molly, a young girl who admired the Peyton from Lucas' book. Over the years she has grown apart from art and closer to music, which she used between others to launch a CD to raise money against breast cancer and create her own label.
As of October 13, 2008, Peyton has been in a total of 111 episodes (only missing from one episode so far- Season 2, Episode 12- when she was out of town with Jake Jagielski).
 Season 1
During the first season, Peyton is the girlfriend of popular jock Nathan Scott, but they soon break up when Peyton reasons that their relationship is more about the "benefits" than love. In addition, she realizes that she does not want to be the star basketball player's girlfriend anymore. She has a romantic interest in her ex's brooding half brother, Lucas Scott. Through various interactions with Lucas, she finds that he is kind and thoughtful towards her, in contrast to Nathans arrogant and cruel treatment of her. Lucas has had a huge childhood crush on the brooding teen and always dreamed that she would be his one day. Because of the encounters he has with his nemesis Nathan, Lucas and Peyton see each other more, soon after producing a spark between the two. However, at a party in Nathan's home, Peyton becomes scared and runs from Lucas after he admits his want and need for her; Lucas is left heartbroken and desperate. Later, at a frat party, Peyton meets up with a guy who puts a date-rape drug in her drink. Peyton's best friend, Brooke, saves her right before she is about to be raped. Brooke then calls Lucas for help and Lucas takes care of her for the night. Oddly enough, Lucas and Brooke bond over taking care of a drugged Peyton.
Peyton later goes to visit Lucas and professes that she wants what he wants. But Peyton is too late; Brooke, who is already in the house, walks in on the two of them, wearing nothing but Lucas's sweatshirt (Peyton then knowing that the two are together). Lucas is then forced to make a decision, and chooses Brooke because he is afraid that Peyton will hurt him again. The two remain great friends, even as Brooke shows jealousy regarding their growing friendship. After taking a trip to see if Peyton's dad was killed during a storm while he was out at sea, an emotionally-wrecked Peyton kisses Lucas. The two lose themselves in heated passion and almost have sex, but Lucas's necklace, which Brooke had given him, gets caught in Peyton's hair and they soon stop what they are doing. On their way home, Peyton tells Lucas to bury what happened and that it did not mean anything. A disappointed Lucas asks if it really did not, with Peyton shortly after saying, "Of course it did." The two remain secret lovers, though no sex is involved, and they finally declare their love for each other. Stolen kisses are shared, but they both know it is wrong, and that they should both tell Brooke.
On the night that they decide to tell Brooke, Lucas gets into a car accident, which brings back painful memories for Peyton because her mother had died in a car crash. Lucas subsequently goes into a coma. When Lucas finally comes home from the hospital, he breaks up with Brooke with an explanation of their relationship not being the best thing for right now. Peyton comes to comfort Lucas for his return, but soon avoids Lucas after realizing how much the breakup is hurting Brooke. Lucas, who feels he has to see Peyton, sneaks out of his house to go see her. As the two begin to talk, Lucas suddenly falls back on her bed with a high fever. Peyton calls Karen to meet the two at the hospital. But Brooke is with Karen at the time and goes to check on Lucas; she catches the two through Peyton's webcam being affectionate in more than just a friendly way, as a passionate kiss is shared between them. Lucas's computer is on, with Peyton's website up on his screen. Peyton ends their secret affair and explains that they are hurting Brooke too much, and says that she does not want to be "a bad person". Lucas is crushed, as well as Peyton. Later that night, Brooke stops by Peyton's and explains she saw her friend and her ex together. She breaks off their friendship. Lucas watches the event unravel on Peyton's webcam.
Peyton continues to avoid Lucas while Brooke continues to avoid Peyton. Brooke declares her friendship with Peyton to be over, but they soon bond over a cheerleading event in Charlotte. After that, Brooke shuns Peyton once again. Peyton begins spending more time with Luke's best friend, Haley James, and with Jake Jagielski, along with Jake's daughter, Jenny. Eventually her friendship with Lucas is slowly reformed, the two even attending a party together at Nathan's apartment. But at the party, Peyton and Nicki, Jake's ex and Jenny's mother, fight. Peyton realises Nicki is the girl Lucas hooked up with at a bar, shortly after getting dumped by Peyton. Peyton is furious and feels betrayed, along with Brooke. This draws a wedge between Lucas and Peyton, but reconciles the friendship between Brooke and Peyton. The season ends with Peyton spending more time with Jake, and helping him escape from Nicki, who tries to take their daughter from Jake's grasp. Peyton's relationship with Lucas remains broken.
 Season 2
In season two, Peyton at first goes through a difficult time. Although at first she has initial success with getting an all-ages club TRIC opened, and with encouraging Haley to perform at the club, which eventually fuels Haley's desire to be a singer, Peyton begins to get involved with cocaine. She feels alone, as her father is away again, and she does not know where Jake is. She feels down that everyone is dealing with their issues and not helping her or realizing that she is upset or going through a very difficult time in her life. She is accused of being a lesbian by Felix Taggaro and faces public humiliation when he writes DYKE on her locker, just so his sister, Anna Taggaro, will not get upset by talk of her being a lesbian (it is later revealed that Anna is bisexual, though she also uses the word "gay" to assert her sexuality).
Hope comes for Peyton when just as she is about to fall off her mantle and buy some cocaine, Jake comes back into her life. It turns out that an argument between Lucas and Peyton made Lucas realize that he had not been there for Peyton, and knew he could not pick up the pieces of her broken heart. As a result, he was the one who called Jake, knowing that Jake would have a positive effect on her. This does, and sparks a turnaround for Peyton, and she and Jake fall in love. But this happiness is short-lived as Nicki comes back wanting custody of Jenny. Nicki eventually takes Jenny away from Jake and runs off, causing Jake to run after her, which leaves Peyton alone and heartbroken.
Soon, someone named Ellie Harp gets in contact with Peyton saying that she is from Alternative Press magazine and wants to do an interview. But when Peyton starts receiving some strange e-mails from someone named 'WATCHMEWATCHU', she begins to suspect that it is Ellie. Ellie, however, denies sending the e-mails and shockingly informs Peyton that she is Peyton's mother. The finale ends with a crying, bewildered Peyton on a beach, and Lucas coming to comfort her. "Looks like it's just me and you this summer," is his response, and the two share a very meaningful hug.
 Season 3
At the beginning of the third season, it is revealed that Peyton is actually adopted, and that her biological mother is alive. It is announced that Ellie is Peyton's biological mother, but Peyton soon rejects her; not able to have a mother who repeatedly lies. Lucas tells Peyton he found Ellie buying drugs the other day. But Ellie later informs Peyton that the drugs are medical ones, for breast cancer. Not long afterwards, Peyton believes her mother and soon connects with her. They even work together to release a CD where its profits will go to the breast cancer foundation. On the same day when the CD is released, Ellie dies, which leaves Peyton devastated.
A school shooting breaks out later in the season, where Peyton is left fighting for her life after being the one shot. She was with Brooke when the event unraveled, but Brooke fled the building without knowing Peyton was not behind her. Brooke tells Lucas that Peyton is still inside, having Lucas then run inside the building to save his friend; he finds her bleeding out of her leg inside the school's library. Peyton cannot walk due to the injury, so escaping is out of the question. Lucas and Peyton stay in hiding. Lucas wraps a tourniquet around her leg, hoping to subside the blood and pain, but as Peyton is falling out of consciousness, he forces her to talk about a fun day she once had. Minutes later, after earning a promise from Lucas about everything being okay, Peyton loses the hope of her surviving, despite Lucas's promise to get her out of there alive, and kisses Lucas; letting him know that she loves him before she passes. However, Lucas returns the kiss. Peyton falls unconscious. Lucas not wanting her to die, carries her out of the building, even at the risk of being killed by the shooter.
Before Ellie passes, she leaves a piece of advice to Peyton regarding Peyton's love life. Peyton decides to give love another try and dates Pete Wentz from Fall Out Boy. Their relationship does not work out, since Pete is busy with touring. Peyton's father tells her to follow her heart and listen to it, so Peyton decides to give Jake a visit in Savannah; she knows that she still loves him and feels that this will be enough for them to be happy. She renews her relationship with Jake and Jenny, and even goes far enough to propose marriage to Jake, who gladly accepts. But that happiness fades once Jake overhears Peyton say, "I love you, Lucas," in her sleep. Peyton is then forced to confront Jake about the kiss she and Lucas shared on the day of the shooting. Jake figures that while Peyton loves him, she is in love with Lucas. He tells her to go back to Tree Hill, and to find out if Lucas is still in her heart. If he is not, Jake promises to still be there, waiting. Peyton does as Jake has advised.
In the season three finale, Brooke ends her friendship once again with Peyton after Peyton tells her that she still has romantic feelings for Lucas. Lucas later tells Brooke about the kiss in the library. At the end of the episode, Peyton burns pictures of herself with Brooke. She then picks up a picture of the three of them (herself, Brooke and Lucas) and rips the part of Brooke off and burns it. She puts her own picture together, Lucas and her, and places it onto the table.
 Season 4
Peyton discovers that she has a half brother named Derek and, with prompting from Lucas, agrees to meet him. But the guy she meets isn't her half-brother, but an internet stalker who is the owner of the "WATCHMEWATCHU" emails and has been taking pictures of her, listening to her podcast, watching her on her webcam, and even going so far as to get a tattoo of Ellie's drawing of her on his back and making a prostitute dress like Peyton before they had sex. Unaware of all this and, in an attempt to be more trusting, Peyton accepts him. However, Lucas soon grows suspicious of this 'Derek' when he catches him sniffing Peyton's hair during a hug and finds Peyton's jacket, which had gone missing, on the beaten prostitute still dressed as Peyton. Peyton soon realizes the truth and, in a terrifying encounter, is manhandled and nearly molested by "Psycho Derek". Lucas and the real Derek come to her rescue, pushing him out a window, but by the time the police show up, he has disappeared.
The event causes Peyton to withdraw into herself, becoming scared and even skipping school and getting four locks on her bedroom door. Derek, who is in the Marine Corps and unwilling to open his heart to people after trying that at first only to watch them die, avoids Peyton until Lucas comes and talks some sense into him. He and Peyton develop a healthy sibling relationship and he helps her come to terms with her fear, not only of Derek but of confessing her feelings to Lucas. Peyton is unwilling to ruin the friendship that she and Lucas have, especially until she is sure that he and Brooke are over. At Derek's encouragement, she asks Lucas to a banquet to honor Whitey, only to find out he is going with Brooke. Disappointed, she takes Derek instead. Derek tells her that he is being deployed to Iraq. That night Lucas comes over to Peyton's to tell her that it is finally over between him and Brooke. She immediately confesses that she's in love with him, to which Lucas just says "Oh." It's not until after winning the state finals that Lucas realizes that it is Peyton he wants and the two start dating, officially this time. Lucas has a heart attack that same night and almost dies, causing Peyton to fear that she will lose him like everyone else and get distant. However, she and Lucas soon resolve this and decide to just be happy.
They decide to go all the way during a party in the room where Peyton first rejected Lucas in Season One, but they are interrupted when Peyton hears everyone cat-calling at what she thinks is a sex tape of her and Nathan. When Lucas and Peyton rush out to put an end to the tape, they, and everyone else, discover that it is in fact, of Nathan and Brooke. Peyton is enraged at Brooke and punches her, giving Brooke a black eye. Later, while at home, she yells at Brooke (who had come to egg her house) that she didn't ruin their friendship. Brooke ruined it a long time ago. Following this, Peyton decides to skip prom, but gets convinced not to do so by Nathan. As she walks to her door to answer it (thinking it's Lucas) the man behind the door turns around and it's actually her stalker, Psycho Derek. He ties her up in his basement and proceeds to make a mock prom for them. Brooke arrives, knowing that Peyton would never skip prom. Psycho Derek tries to kill Brooke, but Peyton pretends to want to do it. Instead, she stabs him. Together, they then defeat him and he ends up in jail. She begins having visions of him and visits him in jail and discovers he was stalking her because she looked like his dead girlfriend. Telling him they both forgive him, she tells him to never come back to her. She then lives together with Brooke, with whom she has made up with. After making sure with Lucas, she decides to take an internship in L.A. and thus spent the whole summer with Brooke.

 Season 6
In the season premiere, it is discovered that the person whom Lucas calls is Peyton. She goes to the airport and they hop on a plane to Vegas to get married. Once they get there, the chapel is too trashy, so they do not get married. Instead, they drive to L.A. and Lucas proposes to her in the same hotel room he did years before. The two are still in L.A. during Brooke's attack. After Brooke calls Peyton and sounds weird, Lucas and Peyton decide to head back to Tree Hill and have the wedding there instead. Peyton sees Brooke beaten up, but Brooke lies and says she fell down the stairs, and Peyton believes her, not knowing that her friend was attacked.  After finding out about Quentin's death, she goes to see Brooke at her store and Brooke, throwing clothes out of her store, begins yelling at Peyton and asks for her house key back in order to feel safe in her home. She later apologizes for this. Peyton also comforts Lucas after Q's death and tells him the wedding can wait until everything is back to normal. 
Peyton meets a famous musician named Mick Wolf, who used to know Ellie. He is the one who asked Mia about Peyton during the tour. He keeps dodging around the subject of Peyton's real father, but says a little more about him each time Peyton brings him up.  Peyton continues to get to know Mick and continues to ask about her real father. Then, something inside her snapped when she asks him why her parents gave her up and he replies, "We... I mean us, all had a tough decision." Mick accidentally let the truth slip out, and suddenly Peyton realized this is her father. She invited him over for a nice dinner together but instead of showing up, he went and got drunk at a bar after being sober for a year (as shown by a sobriety chip in his pocket). She and Lucas have also set a date for their wedding, which causes conflict between Lucas and Lindsey with regards to the book tour for Luke's new book, The Comet. Peyton goes to the studio and finds Mick passed out on a pool table. She wakes him up and she goes off on him, and he reveals he truly is Peyton's biological father. He also tells her that the sobriety chip was Ellie's during her pregnancy with Peyton. Peyton puts up all her emotional walls and is angry with him for not being upfront with her about who he. She tells him to leave. Not long afterwards, during a visit to Brooke's, Brooke tells Peyton the truth about how she got all the bruises on her body. Peyton is later seen on the phone with Larry, her adoptive father. She tells him how much she loves him.  Peyton reads an article in B. Davis Magazine that tells her that couples moving in together know less about each other than they think they do. Peyton and Lucas soon realize this and decide to lock themselves in the house until they are used to living with each other. They play fun little games with each other, like criticizing each other's choices in food and music, to putting a line of tape down the center of the house to split it into two. Eventually, the two decide to accept their differences since it's what makes them such an amazing couple. 
Peyton reconnects with her biological brother Derek, who has returned from the war. They talk about their father Mick and how Derek once asked him to play a USO concert and that Mick never gave him an answer. Peyton decides it's a great idea and says she will put one together.
