After the events of Casino Night, Kirsten and Sandy decide to become Ryan's legal guardian and Ryan officially becomes a part of the Cohen family. For the upcoming Cotillion, Ryan is paired up with Anna, and Summer, much to her dismay, is paired up with Seth. After rehearsal, the kids all go to a pre-Cotillion beach party, but much like the first beach party, Seth and Ryan are thrown into an unwelcoming crowd. This time, however, Ryan is able to resist fighting Luke. Meanwhile, Sandy learns that Jimmy's $100,000 loan from Kirsten has put her into Jimmy's fraud investigation, and the community's anger towards Jimmy's fraud hits its end during Cotillion.
