Three yeas after Peyton saw Lucas at the book signing, she comes início to find out that not only is he still with Lindsey, but that he can't write his segundo novel. Brooke ecourages Peyton to open a record studio and Lucas backs her up por letting her know his mother, Karen, is willing to let her use the back room of Tric as her studio. This causes all kinds of rehash from their past, starting with the proposal that went wrong. But on the night of everyone at Tric, Peyton and Lucas have an argument that causes tension between him and Lindsey and prompts her to leave because she doesn't want to be segundo in his life.

Over the seguinte few weeks things get intense for Peyton. She buries herself in her work with her very first musician named Mia and has Haley on board as help. On the dia of Lindsey and Lucas's wedding, something occurs to Lindsey at the alter in the middle of their vows. She remembers a passage from Lucas's new novel and realizes that he still loves Peyton, "It was mais than just a comet because of what it brought to his life: direction, beauty, meaning. There are many who couldn't understand, and sometimes he walked among them. But even in his darkest hours, he knew in his coração that someday it would return to him, and his world would be whole again... And his belief in God and amor and art would be re-awakened in his heart."
Lucas and Peyton argue over her answer to his marriage proposal.
A few weeks after the wedding gone wrong, Lucas was still hiding out on Andy's barco with him, his mom, and Lily. Andy told him some insightful conselhos on how to pick himself up and this causes Luke to fly to New York to try and win Lindsey back. But she declines and Lucas is mais coração broken.

This leds to awkward moments between Lucas and Peyton, one in which he sees her hair all messy and in her pajamas, which consisted of very short shorts and a big t-shirt.

As time goes on, Peyton realizes a few things in regards to Lucas and what is happening between them, "There's just silence...There's just silence. I come in here and I sit in silence and hear the echoes of who we used to be. And so I wish for patience, and grace, and strength to just let him be happy. Mostly I pray for the strength to not make his life worse because of what I want. That's the toughest part, letting go, you know? That's the part of grace that really sucks." ("Echoes, Silence, Patience, and Grace" - 5.13)

Towards the end of the season Lucas finds out Lindsey had started dating again and causes Lucas to go into an uproar during a Ravens game. He then goes on a drinking binge, which Peyton later finds him passed out at the bar. She takes him, cleans him up, and puts him to bed.

For the rest of the week, Lucas just keeps on going back to Tric and gets drunk since he has no job and is constantly depressed. This somehow leads to one morning Nathan and Jamie coming over to surprise him but find out his hair was shaved into a mohawk (which later makes Jamie think it's cool and causes his nephew to want to same style.)

But Haley shaves the rest of his head, they then go out for a drive, she has him stop at a green light and a water balloon crashes on the front windshield of his car. It was from Peyton, expressing how angry she was at Luke for telling her that he hated her.

After all that, Haley breaks her code of silence and shares information from her and Lucas' childhood. Peyton finds out that since he was 13 years old, Lucas has been in amor with her. She feels inspired and paints the rivercourt as a way to send a amor note to Lucas. He sees it and starts to ponder which girl is for him: Peyton, Lindsey, or Brooke. Haley comes and finds him sitting on the rivercourt and tells him, "You know that romantic notion that all the garbage and the pain is really healing and beautiful and sort of poetic? It’s not. It’s just garbage and it’s pain. You know what’s better? Love. The dia that you start thinking that amor is overrated is the dia that you’re wrong. The only thing wrong with amor and faith and belief is not having it."
Peyton helps a drunken Lucas.
Later on Lucas goes to find Peyton at her record studio over at Tric and confess, "I don't hate you. I remember the first time I ever saw you, all skinny arms and enrolados mess of hair. It was hard letting you go Peyton. You know? It was hard losing you and it was hard seeing you again and it's still really hard." ("What Comes After The Blues" - 5.18). The two realize that they had too much history and that it still meant something after all this time. This prompts Lucas to call one of the girls on his cell phone and ask one of them to come meet him at the airport and go to Vegas to get married.
