S3, E16: Casey tries to finish her personal statement for law school and goes to Joel for help. He tries to get her to write more about herself rather than what she thinks the board wants to read. Katherine offers to help her but it ends up impeding on her relationship with Ashleigh who feels like they're drifting apart. The two decide to go to their freshman dorm reunion and wonder if they're not as good of friends anymore, but meet again in the laundry room and realize they'll always be friends. Rusty takes charge when the KTs get new neighbors - a family! Cappie wants to force them out, but Rusty takes the high road and tries to get them all to welcome the neighbors so there's no trouble. Rusty comes up with the idea of "borging" Tom, the dad, into seeing how fun it is being back in a college environment but it backfires when Tom gets so comfortable he doesn't want to leave. Cappie realizes Tom is who he would love to be some day (never leaving college) and bonds with him until Tom sees he needs to grow up and get real. Cappie decides he doesn't want to change for Casey just because she's growing up though. Rebecca realizes she lost the necklace Evan gave her on Valentine's Day somewhere in the KT house when she went to sleep with Beaver. The OX's find out that there is money missing in the house, so Calvin gives everyone an envelope so the thief can return it anonymously. But when all the envelopes are returned he discovers it was Evan who stole the money (to buy Rebecca's necklace) because he marked Evan's envelope so he could check.
