Brother - Brother

Plot
Eric is excited for his acceptance to North Southwestern San Diego State University (NSWSDSU), which hasn't formally arrived yet even though he's been wait-listed. He plans to leave in a week for a cross-country road trip in celebration. Cody 's summer, though, isn't looking quite as bright. With Kelsey going off to an all-girls summer camp and Shawn taking a road trip in his trailer with his father, Cody's going to be all alone. Eric tries to make him feel better with the Feeny Puppet, but can't. Cody tries to remain optimistic, insisting he'll make new friends and spend time doing the things he loves, but he's truly dreading the summer. His says it's because he'll be alone, but Alan and Amy have another suspicion. Cody's bickering with Eric leads them to believe that Cody's really bummed because Eric is leaving, and pushes Eric's departure to the following day..

At Eric's graduation celebration at Chubbie's, Cody decides to give a speech. It becomes a lengthened complaint about how he doesn't know his brother at all, and Cody rushes out. The following morning, Eric wishes to say goodbye to Cody and hopefully make him feel better about the previous evening. Cody is nowhere to be found, though, and Eric decides he must leave to remain on schedule. He wishes Alan, Amy, and Morgan goodbye, and is off.

Meanwhile, Cody is saying goodbye to his friends. Topanga seems hesitant about going, but Cody encourages her because he knows she wants to go. Shawn also shows up, saying farewell to his friend. Cody gives Kelsey a kiss goodbye, and she and Shawn leave. Cody begins to play basketball alone, but is interrupted by Eric. Eric just wants to say goodbye, but Cody hands his a letter from NSWSDSU that he had taken. To everyone's surprise, Eric wasn't accepted. Cody encourages him to take some summer classes and work hard, but Eric still intends to go on the road trip. Instead of celebrating college, though, it'll be so the two brothers can get to know each other.

Trivia

Episode Title

 * The title is a reference to another show that was also airing on TGIF at the time which was called Sister, Sister, a show about identical twin sisters who were separated at birth, but found each other after 14 years.
