ok soha, here goes....
Sandy checks out an alcohol treatment center before Caleb's funeral. Seth finds the brochure for the treatment center in Sandy's desk while looking for a cell phone charger. Seth assumes it's for his dad but Ryan's pretty sure it's not.
At the treatment center, Sandy explains to the doctor that in the last few months Kirsten's gone from wine to vodka, gotten into a car wreck, and now, with the death of her father, who knows? Sandy informs the doctor that Kirsten's not going to check in voluntarily and the doctor informs Sandy that very few of their patients do.
Jimmy arrives at the Nichol mansion and it's hard to tell who's more excited to see him -- Marissa or Julie.
Hailey arrives at the Cohen home and the two sisters share their mutual guilt about how they treated their father.
Trey comes home to find Jess waiting on his doorstep. She offers him an opportunity to make some easy money. She got a call from some kids who supply all of Garden Grove. All Trey has to do is be prepared to point a gun and look like he means it. Can he do that? Apparently he can.
Afterwards, the crowd gathers at the Cohen home for the post-funeral reception. In the kitchen, Kirsten trades in her wine for vodka. Sandy suggests she pace herself and she suggests Sandy lay off the “Kirsten drink-count” for a while. Julie offers to take over Kirsten-watch for a while.
Summer, who has personal experience with her step-mother's drinking, offers Kirsten a plate of food, but Kirsten doesn't appear to appreciate the gesture. Sandy approaches Summer and suggests she and the gang get out of the house for a while.
In the pool house, Summer suggests they go to The Bait Shop. Marissa's worried about running into Trey but Ryan assures her he's working the day shift.
The gang arrives at The Bait Shop and runs smack into Trey, who claims to be there picking up his paycheck. Jess grabs Trey's hand and leads him upstairs. Ryan watches as a small group of tough-looking guys follow Trey and Jess.
Back at the Cohen's, Kirsten has traded in her vodka glass for the entire bottle. Sandy tries to convince her to call it a night but Kirsten claims to be fine. When Sandy attempts to guide her back into the house, she yells at him to get his hands off her, meanwhile dropping the bottle which shatters on the ground.
Upstairs at The Bait Shop, Jess's customers are testing out the goods. Jess hands them a variety pack but apparently they don't have enough cash to cover the coke. Instead, they suggest a payment plan – they’ll plan to pay her when they feel like it. But apparently they've underestimated the "Newport Bi-itch," as they refer to her, who grabs the gun away from Trey and starts firing at them. Chaos erupts and our gang gets caught in the crossfire.
The next day Ryan stops by Trey's place and tells him he's got to leave Newport. Trey reluctantly agrees to be gone by morning.
Jimmy stops by the mansion with Julie's favorite breakfast food -- powdered donuts from 7-11 -- and suggests that he, Julie and Marissa sail out to Catalina. Julie reminds Jimmy that Marissa doesn’t wake before dusk so Jimmy suggests they make it a twosome. Julie accepts.
Back at the Cohen’s, Seth and Sandy have a heart-to-heart about Kirsten's drinking. Seth tries to make excuses for his mom but Sandy points out that her accident was caused by driving under the influence long before Caleb’s death. Seth thinks there must be another way besides shipping her off but Sandy assures him there’s not. Sandy tells Seth that a doctor will be coming later in the afternoon to help them stage an intervention. Seth tells his dad to count him out. Ryan, on the other hand, speaking from experience, reassures Sandy that he's doing the right thing.
Summer stops by Marissa's room and invites her out for pancakes on the pier. Marissa accepts and Summer tells her they'll go just as soon as Marissa explains the weird bruise on her neck, the bad excuse, and the weird tension with Trey. Summer begs Marissa to tell her the truth but all Marissa can do is cry.
Kirsten and Hailey arrive home from the spa and Sandy introduces Kirsten to the doctor. The doctor explains that her family believes she has an addiction to alcohol and they're worried about her wellbeing. First Sandy and Hailey express their concerns, then Ryan, who explains that his own mother couldn't take care of him because she wouldn't get the help she needed. Kirsten thinks they’re all blowing things out of proportion... until Seth shows up and implores her to go.
Kirsten says goodbye to Seth and Ryan. She apologizes and tells them both how much she loves them.
Jess stops by Trey’s place and sees him packing. She makes him another offer he can’t refuse – this one involves a stack of money, her step-dad’s Beemer, and a trip to Vegas with her.
Ryan and Seth are relaxing in the pool when Summer stops by and asks to talk to Seth alone. She tells Seth that when he and Ryan were in Miami, Trey forced himself on Marissa.
Sandy and Kirsten arrive at the treatment center and check out the new digs. Kirsten apologizes to Sandy for all the hurtful things she said. Then it’s time for Kirsten to go to a newcomers meeting. The nurse informs them that they won’t be able to speak again for 72 hours while Kirsten’s going through detox.
Seth stops by the pool house with something to say, but before he does, he makes Ryan promise not to revert to the old-school Atwood ways. Then Seth tells Ryan what really happened between Trey and Marissa. Marissa fought Trey off so nothing actually happened but that’s how Trey got the cut on his head. Ryan tells Seth that all year he’s tried to be a different person, but he can’t do it anymore. He’s going to settle this with Trey once and for all.
Back at the mansion, Jimmy and Julie announce to Marissa that they’re going to give the Cooper family one more shot. Hugs all around. Marissa’s genuinely happy. But then a phone call from Seth interrupts the family moment with the news that Ryan’s on his way over to Trey’s. And he knows what really happened between them. Marissa takes off.
At Trey’s place, Ryan starts pushing him around when Trey suddenly grabs a gun and aims it at him. Ryan knocks the gun out of Trey’s hand and starts beating the crap out of him. Trey fights back. Marissa arrives and sees Trey’s hands around Ryan’s neck. She tries to break it up but Trey continues squeezing the life out of Ryan. Just as Trey’s about to hit Ryan over the head with a telephone, Marissa picks up the gun and shoots Trey in the back He stands stunned, blood quickly running from his body, and falls to the ground. Seth and Summer arrive in time to witness the tragic scene.
