Cappie is insulted that his effort isn't even reward by an invitation and 'plans' his own party, without any budget. Their pledges are (ab)used, but the results satisfy nobody and makes collateral casualties. Rusty has a 'luxury' problem: if/how to dump his 'fun buddy' Tina.—KGF Vissers

Rusty is trying to figure out his relationship with Tina. He doesnt understand why all she wants is sex.

Rusty meets up with his brothers and tries to figure out what kind of relationship hes in with Tina. Girlfriend, or friends with benefits? Cappie explains to Rusty that hes in a friend with benefits relationship and that he should be happy about it.

Cappie sees Evan outside the liquor stores and finds out that he is having a six way party with all the Greek houses on campus. Every house was invited but Kappa Tau. Cappie decides that he needs to have his own party despite lack of money, beer, and time.

Rusty goes to the ZBZ house looking for his sister for more advice. Rusty tells his sister that he needs to talk about sex. With the situation being too awkward, Casey recruits Ashley to help her out, and to talk to Rusty. But, the advice wasnt enough for Rusty. He talked to Beaver afterward, and he told him just to ignoring her for a few days, and she would just go away.

Back at the ZBZ house, Rebecca, and a few pledges want to attend the Kappa Tau party instead of the Omega Chi party. Even though they were formally asked to attend. Casey decided that instead of banning the girls from going to the KT party. That giving them the job of sober sisters for the event would keep them in line.

At Omega Chi, the party is in full swing. Evan notices many guys giving Casey attention. Evan asks his brother Calvin to look after Casey and make sure she doesnt get too close to any other guys, keeping the field open for him. Calvin has invited Michael to the party at his frat house. Michael does not seem impressed, and also very uncomfortable telling Calvin he had nothing in common with frat guys.

Ashley has already gotten several phone numbers and Casey with none, thanks to Evan and Calvin. Finally the guy Casey had been eyeing all night had come up to her, and started talking. Casey found out that the universe had finally answered her call knowing now that the guy she though was taken was now available.

Rebecca decides that shes not going to wait for permission to go to the Kappa Tau party. Instead, she puts on party clothes, and phones the other pledges to meet her.

Tina is still bombarding Rusty with phone calls and messages. The Kappa Tau party is dead and Cappie has come up with an idea to steal the party from the Omega Chi, along with the alcohol.

Casey is starting to get suspicious with Calvins behavior and wants to know whats going on. Calvin gives her a lane excuse, and walks away quickly. While on the way out, Calvin tells Evan that hes done with chasing after Casey. Evan then approaches Casey and asks her when things calm down if they could have a dance as friends. Casey accepts.

Behind the scenes Cappie and his brothers are in the Omega Chi house, stealing all the liquor they can.

Calvin finally catches up with his date and it is apparent that he wants to get out of there. Calvin is left standing there, while his date goes to get another drink.

Cappie, corners Casey at the Omega Chi party, and asks her why no Zeta Betas had shown up. Casey explains to Cappie, the reason none of them went is because they had already gotten an invitation from Omega Chi and that, the Kappa Tau had thrown theirs together at the last second. Cappie reminds Casey about the Great Gatsby party and how much the Kappa Taus helped. Casey explains that the ZBZs and the Omegas had made up, and that maybe in three weeks the KT and the ZBZ would have an outing together. Cappie then runs off, without saying goodbye for fear of getting caught by Evan, who is not so far away. Rusty is still in line for the bathroom, and lets a pretty girl cut in front of him. She also gives him some advice on how to dump Tina.

When Cappie gets back to the KT house, his arms are full of liquor, and Rebecca is waiting for him.

Evan sees Casey and her new male friend talking and holding hands. It seems like Evan has finally given up, and goes to find himself a drink.

Calvin goes to find his date, and they finally confront each other about what is really going on. Calvin thought the reason Michael was so uncomfortable was because he thought his brothers where homophobic, but really he was only uneasy because Michael felt so much older than everyone else. Calvin and Michael made up with a kiss.

Evan is sitting on the coach when Frannie sits down beside him. Evan spills about his feelings for Casey, and even tells Frannie, about his past attempts to keep guys away from Casey, so that he could make his move. Frannie tells Evan that instead of chasing after Casey he should find a girl to chase after him.

Casey finds out the Rebecca is not on duty, and that she will have to leave the party to deal with one of the girls, who has gotten way too drunk. Casey has to leave her new love interest but tell him shell be back soon.

Back at Rustys dorm, Rusty starts writing an email to break it off with Tina. Although he cant quite find the right words, and decides to scraps the idea.

Casey goes over to the KT house, to get Rebecca to do her job as a pledge. Although Rebecca refuses to, Casey tries to get Cappies help, but he opted out of getting in between Casey and Rebeccas fight. Casey ended up having to take her drunken sister back the ZBZ house. On her walk back, Ryan the boy she had met at the Omega house had found her. Casey apologized for everything that happened that night, but Ryan said, it was okay and that he had a great time anyways. They then both leaned in and kissed except he kissed a little too much, with his mouth fully open leaving Casey with slobber all over her face.

Back at KT the party is going fierce. Rusty has finally broken up with Tina via text message with his frat brothers help. Tina then messaged Rusty back, letting him know that she was fine but that she had Crabs.
