The last scene opens up with the girls checking out of their hotel late Sunday morning. Although they had planned to not be back in Newport until later that afternoon, they all agreed, well everyone except Summer who did not voice an opinion, that they wanted to see the guys some over the weekend before it ended. The camera shows Kirsten talking to the desk clerk, turning in their keys, and then rejoining the other three women as they walk out, this time with a bellboy handling their luggage. They talk amongst themselves as they exit the hotel.

Kirsten: Well, I must say, this was fun girls. We should do it again.

Marissa: (She laughs.) I had fun, too, but if I told Ryan any time soon that just the girls were going away again for the weekend, he would probably lock me up with him in a room and swallow the key.

Kirsten: (She laughs.) So I take it he wasn't too thrilled with the idea of being separated for less than 48 hours?

Summer: (She snorts.) You could say that again! You should have seen the death rays he shot at me when I drug Coop away from him during their very non-G rated goodbye Friday evening.

Marissa: Sum, it wasn't that bad!

Summer: Oh, I beg to differ! If I hadn't of walked in when I did, you two would have been horizontal…. (She is cut off by Kirsten yelling frantically.)

Kirsten: I think our car just arrived!

Zoe: (Kirsten shoots Summer a look showing her that she has to watch what she says in front Zoe, which elicits an apologetic grin from the brunette.) Can I sit with Marissa?

Marissa: Actually, Zoe, I thought I'd drive home if that's okay. Your Mommy drove down here, and this way you two can relax and watch a movie while Summer and I talk.

Zoe: But, I want to talk with you, too. (She stops Marissa and takes her hand in her own and looks up at her with pleading eyes. The car did arrive just then so Summer and Kirsten loaded their bags in while Marissa talked to Zoe.)

Marissa: Zoe, honey, did you notice this weekend how Summer was kind of sad?

Zoe: (She thinks about this for a moment.) Yeah.

Marissa: Well, I want to find out why, so I have to talk to her with just the two of us, but I promise that if I need any help, I'll come to you, okay?

Zoe: Deal!

Marissa: Plus, I need you to keep your Mom entertained while we talk. We don't want her to get lonely, do we?

Zoe: No! (Marissa smiles at her.)

Marissa: Good. (She begins to stand up, but Zoe launches herself at Marissa and hugs her tightly. Marissa ends up standing up and just carrying Zoe with her to the car where she puts her in the back seat.)

Kirsten: Are you sure you want to drive Marissa?

Marissa: Sure, it's no problem. (She winks at Zoe, who smiles mischievously and turns to her Mom.)

Zoe: Mommy?

Kirsten: (She climbs in beside her daughter.) Yeah?

Zoe: Can we wear the headphones while we watch the movie? (Kirsten laughs.)

Kirsten: Sure. (As she gets the headphones out, she doesn't notice Zoe wink back at Marissa. Marissa closes Zoe's door and laughs softly to herself before climbing into the driver's seat and pulling out of the hotel parking lot. The camera leaves them and goes to the Cohen family room where Neil, Seth, Caleb, and Sandy are all still sleeping, slightly hung-over from their weekend activities. Caleb is on the couch while Neil and Sandy each have a chair and Seth is rolled up in a little ball on the floor with the rug pulled over him as a blanket. Slowly, Neil awakes at the sound of his beeper going off. He groggily gets us and shakes Sandy awake.)

Neil: Hey Sandy, sorry to…. (He yawns.) wake you, but I just wanted to thank you for the weekend and let you know I have to head off. I just got paged to the hospital.

Sandy: (He yawns as well.) No problem, anytime Neil. (There is a slight pause while Neil looks around for his keys.)

Neil: Do you know where I left my keys?

Caleb: (He heard them stirring around and wakes him. After rubbing his face to get the sleep out of it, he responds.) I think we all left them on the table by the front door.

Neil: Ah, I believe you're right. (He starts walking off and talks over his shoulder.) See you guys later. (Sandy looks down at his watch but it is not there.)

Sandy: Oh, hey Neil, do you know what time it is?

Neil: (Neil looks at his watch.) It's around 11:30.

Sandy: Thanks…..what, 11:30? Dmn, I need to get this place cleaned up before Kirsten gets home. (He jumps up and moves to the kitchen in a hurry making Neil laugh and Caleb smirk.)

Caleb: Well, I should be going to. I've put off work long enough. Wait up Neil, I'll walk out with you. (Caleb stands up and the two men walk off to the foyer and grab their keys. Neil opens the door and exits first while Caleb follows. As soon as they're gone, Seth flips the rug off of and sneaks out of the family room through the foyer and out of the living room doors so that he wouldn't have to help his Dad clean up. He doesn't even bother to knock on the poolhouse doors but enters it without any warning. Ryan is still sleeping, and much to Seth's amusement, hugging a pillow tightly to his body with his back to him. Seth decides to play a trick on him and speaks in a girly voice.)

Seth: Ryan, oh Ryan baby, wake up….I'm bored. (His voice at the end sounds like he is pouting.)

Ryan: (The camera moves around and shows that his eyes are wide open and that he is smiling wickedly, but his voice sounds like he is still half asleep.) Marissa?

Seth: Yes.

Ryan: Come closer. (Seth snickers and moves so that he is standing on the bed next to Ryan looking down at him, but before he can plant his feet, Ryan spins around and with the pillow he was holding, hits Seth as hard as he can and makes him fall over rather ungraciously.)

Seth: (His voice shows his annoyance.) Dude, what the hell!

Ryan: What? That should stop you from EVER doing that again! How many times do I have to tell you that what you just did is really creepy and slightly more than just a little weird?

Seth: Or was it weird because you really thought I was your girlfriend and were turned on?

Ryan: I can't even believe you would ask a question like that, but no, I did not think you were Marissa and I was not turned on. (The next part he says without even thinking about the consequences.) Trust me, Marissa wouldn't talk about being bored; she'd fix it so that she wasn't.

Seth: (He snickers.) And thank you for that piece of information. I'm sure we can have many pleasant dinners with that as fodder for conversation….all at Marissa's and your expense.

Ryan: (Because Seth has thoroughly ticked him off, he does not go about starting this conversation the way he had planned.) Or maybe we could talk about your mystery love that you talk to on the phone.

Seth: Yeah, well….what? (He starts to panic.) How the hell do you know about her? (He jumps off of the bed and starts to pace around the room. Ryan, who was shirtless, grabs his discarded wife beater from the night before and slips it over his head before getting out of his bed and going to sit in the chair.)

Ryan: So Summer was right! I can't believe you; what the hell is wrong with you, man?

Seth: What are you talking about?

Ryan: You're having an affair!

Seth: What, no, I'm not having an affair, but Summer really thinks that I am?

Ryan: Yeah. Seth, she walked in on you telling some woman over the phone that you loved her and that Summer still had no idea about her. What was she supposed to think?

Seth: And what did you tell her?

Ryan: I told her that it was all just some misunderstanding, that you would never cheat on her.

Seth: Good, because I wouldn't.

Ryan: Then what is going on Seth?

Seth: (He stops pacing and goes to sit on Ryan's bed, but stops himself and looks at Ryan before asking him a question.) These have been washed since the last time you and Marissa both slept in this bed, right?

Ryan: I guess, I don't know. Just sit down. (Seth looks at the bed one more time, fully stands up, and moves to sit on the floor. Ryan just rolls his eyes but does not say anything but waits for Seth to start talking.)

Seth: Okay, I can't tell you who I was on the phone with, but I'm not having an affair; I never would. There is no way I could do that to Summer; I love her too much.

Ryan: Wait, why can't you tell me who it is?

Seth: I can't tell anyone. The person asked me not to. But I was going to talk to you about the situation anyway. There's a problem. Okay, look, this person was around more before you moved here, and although you know them, you don't know them, know them.

Ryan: Seth, you're not making sense.

Seth: That seems to be a common problem. Focus Ryan, follow my train of thought here. So, anyway, I think this person is sick, really sick, but they won't go and get themselves checked out, but I can't go and see them because they don't live around here and I'd have to tell Summer where I was going if I went to see them, but I promised I would not tell anyone that I was in contract with her, because she really hasn't stayed in contract with anyone else.

Ryan: What do you want me to do about it?

Seth: Go and see her for me, spy on her, report back to me how she looks, take pictures.

Ryan: I'm not going to stalk your mystery lover.

Seth: First of all, she's not my mystery lover; that would just be wrong, and secondly, what is with you guys? You're all a bunch of freaking chickens, afraid of getting arrested for stalking.

Ryan: Who else have you asked to do this?

Seth: Branning.

Ryan: Wait, you went to Branning before you went to me or Marissa?

Seth: Yeah.

Ryan: (He smirks to himself.) What's going on with you two?

Seth: Not this again! First Marissa, and now you, can you please just be serious for five minutes?

Ryan: This coming from the guy who believes that it is never too early to joke after a traumatic event?

Seth: Yeah, well, not when the possible traumatic event is the demise of Sethummer, the greatest super couple ever created.

Ryan: You're doing it again.

Seth: What?

Ryan: Talking about yourself in the third person.

Seth: It's the stress getting to me. (He speaks again after a slight pause.) So, what do you think I should do?

Ryan: Just tell Summer the truth, that you're talking to someone from the past who's important to you, you think they're sick, and that you can't tell her who it is because you promised you wouldn't.

Seth: Like that will ever fly with Summer!

Ryan: Well then, keep putting your relationship in jeopardy. Do you know what she said to me Friday; she said there might not even be a wedding. (Seth gets a puzzled look on his face, but doesn't say anything.)

Seth: I guess I better call my mystery woman and talk it over with her before Summer gets back.

Ryan: Might be a good idea.

Seth: (He stands up and moves towards the door.) Hey, before I go, how's your relationship, man?

Ryan: Good.

Seth: A one word answer, the classic Ryan Atwood response. Glad to see nothing really changes around here. (With that he walks out of the poolhouse, shutting the door behind him, and leaving a slightly grinning Ryan behind as he cleans up the room and makes the bed before Marissa gets back. The camera leaves them and goes back to the four girls who are still on their way home. Kirsten and Zoe fell asleep watching the movie, just as Marissa assumed they would and Summer was just staring out the window lost in thought. There is music playing in the background softly, Badly Drawn Boy's "Silent Sigh". Marissa, who has been collecting and organizing exactly what she wants to say, finally breaks the silence by addressing Summer.)

Marissa: So, how are you really doing?

Summer: (She turns around momentarily startled by Marissa's voice and not expecting that question.) What do you mean?

Marissa: Well, first of all, we have your little surprise trip home to see your Dad Monday, the fact that you've barely been around the apartment all week…

Summer: (Her tone is accusatory and biting.) I thought that's how you and Ryan wanted it.

Marissa: That's not fair.

Summer: Well neither is the fact that you're ditching me all summer long to hang out with him.

Marissa: Summer, I'm going to say this once, and then I'm not discussing this again with you. Yes, I'm spending the summer in LA with Ryan, but it's not about you or Seth; it's about what's best for us. We have jobs, full time ones, and it would be very stressful to have to deal with commuting back and forth everyday, and even if we did, you'd never see us on the weekdays anyway, and on the weekends, Ryan and I would want to be by ourselves, catching up from the week before, but this way, when we're home on the weekends, we'll be able to spend more time with the family. Plus, and I'm not saying this to hurt you, but if I had the choice between spending time with Ryan and spending time with you, I'd choose Ryan every time, because not only do I love him, but he is my best friend. I'd hope that you would feel the same way about Seth.

Summer: (Her voice becomes soft and the emotion expressed in it is raw.) I used to, but now….

Marissa: Sum, he's not cheating on you.

Summer: (Her voice grows louder and is agitated and annoyed.) How would you know!

Marissa: (She looks in the rearview mirror to see if the other two passengers were still sleeping. They were.) Because I talked to him about it, but why would you ever think that Seth is cheating on you?

Summer: Because I overheard a phone conversation he was having.

Marissa: And?

Summer: And he told the woman that he loved her and that I had no idea about her.

Marissa: Okay, so I can see how that would make you think he was cheating on you, but there must be another explanation, because he told me he wasn't cheating on you, and I believe him. If you could have seen his expression when he said it, you would believe him, too. Sum, he still can't even believe that you agreed to marry him.

Summer: (She turns to look a Marissa with a small smile on her face.) Really?

Marissa: (She takes her eyes off of the road briefly to look her friend in the eyes.) Really. (She pauses for a second.) Is that all there is?

Summer: No, there's more, but if you don't mind, I think I'm talked out right now.

Marissa: Okay, but just talk to Seth, and you can always come to me when you're ready to discuss what else is bothering you.

Summer: Thanks.

Marissa: For what?

Summer: For being there even when I continue to push you away.

Marissa: I've told you before, you're going to have to do a lot more than say a few mean things to get rid of me. You're stuck with me.

Summer: (She laughs.) I could think of worse things.

Marissa: Why don't you try to sleep? We still have about an hour left to drive, and I doubt you slept much this weekend with this weighing on your mind. (Summer just smiles at her before closing her eyes and settling back down in her seat with her head resting against the cool window. The camera leaves them and goes to the Cooper house where Jimmy is knocking softly on Caitlyn's door.)

Jimmy: Caitlyn? (He waits for a second.) Caitlyn, are you in here, it's me, Jimmy…uh, Dad. I just wanted to check on you, see how you were feeling, perhaps ask if you wanted to go out and grab something to eat, just the two of us. (There is still no answer.) I hope you're dressed, because I'm coming in. (He opens the door and steps into the empty room. He first goes to her bathroom, but she's not in here as the open door easily reveals. He checks her closet next, but she's not in there. Finally, he goes to her window, which is open wide and looks out of it. He sees how easy it is to get down from it and then glances to the driveway where he sees only two cars. His car is missing.) Sht! (He takes off running out of the room, not even bothering to shut her door and the camera pulls away from him and goes inside of a jail. Caitlyn is there, sitting timidly waiting to talk to Trey. She is dressed, once again, in baggy clothes. Her hair is in a simple ponytail and she is not wearing any makeup. As she waits, she fidgets with her shaky hands and tries to keep herself as calm as possible by breathing deeply. Because she was looking down, she did not see Trey being led in, and when she moves her eyes up to glance around the room, she almost faints when her eyes lock with Trey's who are watching her with humor dancing in them. He picks up the phone and motions for her to do the same with a sneer on his lips.)

Trey: Well, well, well, look who it is, my loyal girlfriend. I was not expecting to see you here. Imagine what gossip would say if they knew Newport's latest princess was in a jail visiting a convict and not for some charity of the week.

Caitlyn: (She's whispering.) Shut up Trey.

Trey: I'm sorry, I didn't hear that. Could you say it a little louder? (He is baiting her, and it works. When she speaks the next time she is practically screaming.)

Caitlyn: Shut up Trey! (The guard gives her a warning look which just makes Trey laugh at her.) I didn't come here to listen to you talk or for you to mock me. I came here, hoping that finally confronting you about everything you did to me would maybe let me sleep through a night, would help me not hate myself, not to feel so dirty.

Trey: Fine, talk, this is sure to keep me entertained for a while.

Caitlyn: Was I always just a mark, or did you decide to use me after you started dating me, when you found out who I really was and that I was related to Marissa?

Trey: Always a mark. What would I want with a seventeen year old virgin?

Caitlyn: Unfortunately I can't say I still am one. (He laughs.)

Trey: No you can't, but I hope the next guy who has you sees a little more excitement. You were like screwing a lifeless doll.

Caitlyn: Does that include the time you raped me in Reno?

Trey: (His voice becomes harsh.) What the hell are you talking about?

Caitlyn: (Tears start to stream down her face.) I said no, Trey.

Trey: So what, you were my girlfriend….

Caitlyn: Yeah, under false pretenses.

Trey: And if I wanted to have sex with you, I got to. No questions asked.

Caitlyn: That's not how it works.

Trey: In Chino, it works like that.

Caitlyn: Well, I'm not from Chino, and it doesn't work like that there either. You're just too much of an animal to know better. You didn't even use protection!

Trey: So what? I like it better that way.

Caitlyn: You could have gotten me pregnant, and who knows what diseases I picked up from you. (He laughs.)

Trey: Yeah, that would be an interesting thing to explain to your society friends and dates. 'Who's this,' they'd ask when they see your kid. 'Oh, that's my kid with my ex. He's a convicted felon.' Great first date conversation, and then you'd have to break it to them that you're not exactly Newport Beach clean anymore. (He laughs again.)

Caitlyn: Don't flatter yourself, I'm not pregnant.

Trey: Too bad. That would have ruined your life for good.

Caitlyn: Why do you hate me so much?

Trey: Why do I hate you? Why? Because you sit there in your designer clothes and judge me, knowing that you have a mansion to go home to when you're done here, that you have rich grandparents and you'll never have to work a day in your life! That's why I hate you!

Caitlyn: And that's why you hate Ryan and Marissa, because they now have money by association?

Trey: Partly, but Ryan's also happy, and that's not how we Atwoods are supposed to live our lives, and we intended to fix that.

Caitlyn: Too bad you failed.

Trey: I might have failed, but my Dad's still out there, and he hates Ryan and Marissa….and you even more than I do. (He moves closer to the glass and smirks at her.) And he knows who you are, trust me, I made it quite clear to him. He knows where you live, where you go to school, where you hang out, and it wouldn't surprise me if he isn't watching your every move. (He laughs viciously.) You're not safe yet, sweetheart! (She starts to shake uncontrollably.)

Caitlyn: I hate you. I hate you! (Her voice continues to rise until she is screaming and sobbing at the same time.) I HATE YOU! (The guard comes to her and makes her hang up her phone. As Trey is led viciously back to his cell, since his guard heard the conversation and was not too impressed with what he revealed, the guard on Caitlyn's side, gently helps her leave the room and shows her out. As she walks out, she is barely holding it together and Trey is just laughing at her the entire time. Music starts to play as they both leave. The song is Lit's "Miserable". As Caitlyn reaches her car, she is barely holding it together and rummages through it until she finds what she is looking for, her recent form of release, alcohol. She pulls out a bottle of vodka and takes a deep drink from it. Before she pulls out of the driveway of the prison, since she will be going past guards, she hides it once again. She waves at he guards with her hair in her face as she passes them so that they can't see her devastated and tear-stained face. Once she is out of the prison compound, she takes the bottle out of its hiding spot, opens it, and takes another long drink, holding it in her hand as she drives with the other down the California interstate. As she is crying, she tries to find her cell phone, still holding the bottle of vodka and taking drinks every couple of seconds. Finally, she accidentally drops the bottle and it spills its contents, but she is able to find the phone. Dialing haphazardly and swerving into the other lane, resulting in some horns to be sounded in her direction, she finally manages to finish the call and holds the cell phone to her ear. While she talks to the person, the camera switches between them.)

Marissa: Hey Caitlyn, how are…. (She hears her sister's sobbing.) What's wrong?

Caitlyn: I'm so sorry, Marissa, so sorry. (Her voice is slightly slurred because of the alcohol.)

Marissa: For what, Caity?

Caitlyn: For causing all this to happen to you, for bringing him to you that night.

Marissa: But Caitlyn, you didn't do anything wrong. He lied to you, and he was after Ryan and I even before he met you.

Caitlyn: Yeah, but he wouldn't have been able to go to that party if I hadn't of invited him!

Marissa: You didn't know who he was. He lied to you. You're a victim here just as much as I am, if not more. Are you listening to me?

Caitlyn: (She hiccups.) Yeah.

Marissa: Wait, have you been drinking?

Caitlyn: I…uh….maybe.

Marissa: How much? (She does not answer her.) How much Caitlyn!

Caitlyn: (Her crying is getting louder so it is hard for Marissa to hear her.) A lot.

Marissa: Let me talk to Jane, now.

Caitlyn: She's not here.

Marissa: Who's there with you then?

Caitlyn: No one.

Marissa: What! We had an agreement that you'd never be left alone, and a few days after we make it, they leave you home alone! That's it; you're coming to live with me today. I'll be at the house to pick you up in a little over an hour. I just have to drop the girls off.

Caitlyn: I'm not at home.

Marissa: (This throws Marissa slightly and surprises her.) What do you mean? Where are you?

Caitlyn: In a car.

Marissa: With whom? Let me talk to whoever is driving.

Caitlyn: You are; I'm driving.

Marissa: Caitlyn! (She yells loud enough to wake Summer up who turns around and watches a very upset and worried Marissa talk to her sister on the phone.) What the hell are you doing! You don't have your license and you've been drinking. Pull over right now. I'll send Ryan after you.

Caitlyn: NO! Just listen to me. I'm sorry, I'm so, so, so sorry for everything that's happened.

Marissa: (She interrupts her.) Caitlyn pull the car over now.

Caitlyn: (She is so lost in her own world of pain that what Marissa said did not even register. She keeps driving and her voice rises to a scream.) I'm sorry that I started seeing him, I'm sorry that I let him use me, I'm sorry that I slept with him, I'm sorry that I let him rape me and that I didn't say anything….

Marissa: (Her voice is soft and she is crying now, too.) He raped you? (When Summer hears this, she jumps into action. She wakes up Kirsten but motions for her to be quiet. Kirsten leans Zoe, who's been sleeping on her, down on the seat, and she listens to the conversation. Summer, through hand motions, shows Marissa that she needs to pull over.)

Caitlyn: (Her sister's softly stated question was not heard.) I'm sorry that he gave me your necklace. I didn't know it was yours, and I'm sorry that I wore it. I'm sorry that I invited him to your party, that I ruined it by bringing him, that my bad judgment helped him attack you again. I'm sorry for giving him an alibi for the night he first attacked you. I'm sorry for going to Reno with him. I'm sorry for telling him things about you and Ryan, about your lives. I'm sorry for being a bad sister, for not being there for you. I'M SORRY! (Finally, she breaks down and just sobs uncontrollably. Forgetting what she is doing, she lets go of the wheel and cradles her head in her left hand after her right one drops the phone, she uses it to hold her head as well.)

Marissa: Caitlyn, Caitlyn, can you hear me? (Because Caitlyn has dropped the phone, she doesn't hear Marissa's voice and Marissa can't hear anything but softer sobs coming from her sister. As the music gets louder, Marissa continues to call for her sister.) Caitlyn, please, say something, anything. Let me know that you're okay! Caitlyn! CAITLYN! (Still, there is nothing, and then, over the phone, Marissa, who is, by now, practically hysterical herself, hears horns blaring and the shrieking sound of crashing metal and then complete silence. The scene goes black and the episode ends.)

End of Episode #16
