It's the morning of Seth's wedding, he and Ryan are in the poolhouse having some last minute Seth/Ryan time

Seth: Hey Ryan do you think I could borrow one of your wifebeaters for the honeymoon I think Jess will find it sexy.

Ryan: Seth, we've been through this - NO WIFEBEATERS!

Seth: Still can't pull em off eh!

Ryan: Sorry man but NO!

Seth: Okay how do I look?

Ryan: Good, are you ready? We're going to be late, only the bride is supposed to be late not the groom!

Seth: Okay I'm ready (Seth pauses) Holy Moses & Jesus - I am getting married today! I Seth Cohen am getting married today!

Ryan: Not if you don't get a move on now come on...

Seth & Ryan make there way down to the beach, the guests are beginning to arrive, everything is beautiful.

Sandy: Son, you look great

Kirsten: Sweetie (Embracing Seth) I can't believe my Seth is getting married today, you look so handsome

Seth: Thanks Mom, thanks Dad as always look are looking pretty darn great yourselves

Sandy: We're so proud of you son, Jess is a great girl

Seth: I am lucky to have her

Sandy: She is lucky to have you

Seth: Okay I better go, it's nearly time

As Ryan is making his way to the top of the aisle to stand along side Seth as his best man he bumps into...

Woman: Ryan

Ryan: Marissa

Marissa: Wow, I can't believe it's you, you look so grown up

Ryan: Well it's been five years

Marissa: Five years, no it can't of been that long (knowing how long it's been to the day)

Ryan: Graduation Day - USC

Marissa: Your right, well it's been too long

Ryan: Yeah it has, it's been great to see you again

Marissa: You too

They both share a moment, their eyes catch one another)

Ryan: Listen I have to go and be a best man now but we should catch up after the ceremony

Marissa: I would like that

The two part, occasionally glancing back at one another as they walked in separate directions)

Seth: Where is she man? She's late

Ryan: Chill man, she's the bride, she's meant to be late

Seth: Was that Marissa I saw you talking to?

Ryan: Yeah can you believe it. She is still as gorgeous as ever. We're going to catch up on old times after the ceremony

Seth: Ryan, be careful. Don't let her do this to you again

Ryan: It's not like that this time, just friends

Seth: When have you to ever been just friends

At that moment Seth is cut off by the sound of the 'Wedding March'
He turns around to see Jess walking up the aisle but instead he see's her sister Mandy running towards him

Seth: Mandy what's wrong? Where's Jess? Is she alright?

Mandy: Seth I don't know. She's not coming, she left a note

Mandy hands Seth the note

Seth

I am so sorry I have to do this to you, but I can't marry you. It's not right. I haven't felt it's been right for a long time now, but I've only had the courage to tell you now before we both make a big mistake that we'll regret. This is for the best and I hope someday you can forgive me.

Jess

Seth stands there in silence an hands the note to Ryan and walks down the aisle, the guests staring at him wondering what has just happened

Seth walks into the kitchen to the sound of his parents and Ryan talking about him

Seth: You can stop talking about me

Kirsten: We're sorry sweetie we're just worried about you

Seth: I think I am the one who should start worrying this is the second woman who I've loved that's left me because she didn't love me. At this point I am starting to think 'is it me?'

Sandy: Son, come have some breakfast, we have bagels!

Seth: Yes because a bagel can solve all my problems

Sandy: Well it has been known

Ryan: Seth, I hate to leave you like this but I told Marissa I would meet her for breakfast

Seth: Go man, don't feel like you have to babysit me afterall I was just left at the alter

Sandy: Ryan, go ahead, we'll take care of Seth

Seth: I am here you know, I can look after myself, Jess broke my heart not my legs

Ryan: Okay if you are sure, catch you later

Seth: I am not going anywhere, nowhere to go

Ryan: Hey

Marissa: Hey how's Seth doing?

Ryan: Not great, he's in the self pity stage

Marissa: Do we know why Jess left him yet?

Ryan: No, it seems she just fell out of love with him

Marissa: It happens, I should know

Ryan shoots her a look, there was an awkward silence between the two

Ryan: Have you ordered yet?

Marissa: No I waited for you

Waitress: Can I take your order?

Ryan: Bacon, eggs and black coffee

Marissa: Just eggs and a black coffee for me thanks

Marissa: So tell me about Ryan Atwood

Ryan: Well after graduating I came back to Newport to begin an internship at the Newport Group working with Kirsten. I am an architect, I've just finished working on Newports new beach club

Marissa: I've seen it, it's wonderful, you've done really well for yourself

Ryan: What have you been up to?

Marissa: After college I move to San Francisco, I am counseller I work with kids with drink and drug problems. It took me a long time to deal with all my issues, it's still a battle every day but I've been clean for three years now.

Ryan: Marissa that's great, I'm sorry I wasn't there for you, even though we broke up I should of supported you

Marissa: Ryan when you broke up with me before graduation I was so hurt and angry with you I couldn't see why you were breaking up with me, I couldn't see all the damage my drinking and drug taking was causing you

Ryan: I couldn't handle it, I loved you so much yet I couldn't see an end to all the hurt. I couldn't go through what I went through with my Mom all over again

Ryan: I feel awful that I wasn't there for you, even as a friend, I could of helped

Marissa: I hit a real low patch when you left me that took me two years to get out of. It was tough, but it was me that needed to get clean, I needed to do it by myself

Ryan: I am so proud of you

Ryan placed his hand on Marissa's they both felt a spark)

Ryan returned to the Cohen's to find Seth collasped on the bed in the poolhouse

Ryan: Seth how are you doing?

Seth: I should be in Paris right now walking along the Seine with Jess

Ryan: That sucks, sorry man, listen you were better off that you found out before the wedding that she didn't love you because if she hadn't dumped you at the alter you'd now be in Paris living a lie and that would be worse

Seth: I need to get away from here, everywhere I go I am reminded of Jess

Ryan: Sure, roadtrip?

Seth: This is one I need to do alone

With that Seth jumps up off the bed and heads to the apartment that he and Ryan share, he picks up a few essentials and heads to the airport

Ryan: Seth where are you going?

Seth: Paris

Ryan: Seth is that such a good idea

Seth: Ryan I need to do this

Ryan: Okay good luck

Just as Seth leaves Marissa comes over to Seth & Ryan's apartment

Marissa: Was that just Seth I was speeding off

Ryan: Yeah he's going to Paris

Marissa: Paris? Paris? You're sure he said Paris?

Ryan: Yeah positive, why?

Marissa: It's just that Summer lives in Paris!
