-5.08 isn't Lindsey's final episode. The actress who portrays Lindsey is definitely in 5.09. At least from what I understand. She has already filmed scenes for 5.09 on Friday and has more scenes in the episode slated to film.

-I think at some point in 5.09, for some period of time, Haley, Peyton, Lindsey, Mia, and Brooke will find themselves trapped/locked in the library together

- Most of the episode takes place in the Tree Hill Library.

-One scene they filmed was with Sophia, Hilarie and two new girls. They filmed at school, in the library. One of the girls there had dark brown hair and it was kinda short.

-Lucas and Nathan are driving to Dan's parole hearing in Nathan's Range Rover. Lucas asks how it went with Haley. Nathan tells him she'll need some time, and Lucas tells Nathan to give it to her as Nathan owes her that. Nathan makes a comment on how it would have been nice for them to have a father to go to for advice (scene 23).

-John is congratulating Peyton as Mia enters and ask what for. Peyton tells Mia that it's in her best interest and Mia snaps back. Reminding Peyton that that's not what she said earlier today. She'd called John an evil snake who couldn't be trusted. John tries to tell Mia that despite what Peyton said then, she's making sense now. Mia disagrees and tells John that she will never play for play for him, ever. She's an artist, not a business transaction. Mia tells Peyton that she thought they had something special and that Peyton sold her out. Peyton calls after her, with no luck. John looks on, frustrated (scene 25).

-Nathan/Lucas at Dan's parole hearing: Dan makes a speech to the parole board about how if he's allowed parole, he'll devote his time to helping his family and those he hurt by his actions. Lucas, clearly not buying this, tells the parole board that Dan abandoned him and that Keith was always there for him. Lucas states that he's getting married next week, and that Keith would have been his best man. Lucas asks how a father can hope to be an influence on sons who have never come to visit him in prison. The parole administrator states that the file indicates that Nathan recently went to visit Dan. Lucas is startled by this (scene 26).

-There was a dinner/reception scene filmed.

-Lucas and Lindsey's wedding and breakup is in this episode.

The following (credit to Taylor)

-Lucas is in a black suit with a white satan tie. Peyton is in a strapless grey dress with black beads on it.

-The ceremony starts, but Lindsey is the one to stop it. Lucas has a flashback of the tow truck scene and straight from there after it comes back to present time that is when Lindsey takes off down the isle. Lindsey literally runs away and leaves Lucas at the altar. No words exchanged .He stands there a little dumbfounded and looks quite hurt in his facial reaction. Haley runs out after her.

-We also filmed a scene where Peyton has a “dream” or it is considered a dream sequence. The extras were asked to stand right outside of the door to throw birdseed up in the air. I thought it would be Lucas and Lindsey of coarse but it happened to be Lucas and Peyton and Haley and Brooke both are there as Peyton’s bridesmaids in matching teal dresses. Peyton kisses Brooke on the cheek and her and Lucas ride away together in the Comet.

-Hilarie also filmed a short scene where she just sat in her car outside of the church “thinking” this could be when this dream comes to light.

-This is Micheala/Lindsey's last episode (but also, most likely, the last episode of the season).

-Chad filmed a shirtless scene with Michaela. It takes place after the wedding and the script called for tears.

-Chad and Micheala filmed a LL scene back at Lucas's house. After she runs out of the wedding he finally goes to look for her after a little push from someone close to him that cares. He finds Lindsey at his house and her bags are packed. She goes on to say it won't work because his heart is conflicted and he never stopped loving Peyton. She goes on to say she always knew she just didn't want to believe it herself. Lindsey quotes a bunch of lines from his book that involve the Comet. Lucas says he doesn't want her to leave and she replies "Lucas, people always leave...you out of all people should know that."

-Lindsey does read his second book. During their break-up she says his book is a love story while he tries to say it's metaphoric.

-Nathan is the person that gives Lucas the advice to go after Lindsey. He tells him to look into his heart and if she is still there to go after her. Lucas says that he still wants to be with her so Nathan tells him to go find her. Of coarse there is more brotherly love in this scene including a hug so thats something.

-After the wedding, Peyton is reflecting over the events alone in the church. Brooke comes to sit with her and encourages her to go after Lucas. Peyton then responds about how it doesn’t really matter because he went through with saying “I do.” Brooke then says something like “shut the hell up bitch!” Peyton motions upward to symbolize the fact that they are in a church and Brooke then apologizes and goes on to tell Peyton that she doesn’t need to give up. That’s the only dialogue I know of which is why I am unsure of how this scene ends. I don’t know if Peyton actually goes or just goes on sitting there. This is a very nice scene for the BP relationship. There’s loving words and hugs exchanged. Although Mark is free to edit. (I got the sense that Peyton really thought it was over when Lucas said “I do”. Like it ended their journey together for good and she was just kind of mourning her loss even though she doesn’t come across as whiny just hurt and confused.)

She goes on to say two years ago he proposed to her and she was scared so she said someday. She tells him that someday is now and she loves him and pleads for him not to leave her again.

Peyton tries to absorb this and Brooke says it’s ok, that Lucas looked freaked out too. Brooke hugs Peyton again and Mouth and Millicent approach looking for Jamie.
