S06E14: Getting Hitched

Cory and Topanga play "The Fiancée Game" to prove how compatible they are, and are crushed when Eric and Rachel prove to know far more about each other than they do. Topanga suggests a quick solution: they should live together on campus and really get to know each other. (Cory mistakenly thinks this means sex and buys satin pyjamas and sheets.) Living together shows them sides of each other they're not too crazy about: for example, his big toe clipping flies across the room and lodges in her already-applied facial cream. Meanwhile, Shawn has ignored Jack's repeated call about clearing out Chet's trailer, and, once persuaded, is freshly outraged to discover evidence that Chet went to Jack's stepfather for help in financing Shawn's college education. He decides to take the trailer out on the highway and convinces Cory to accompany him "for the weekend," but oddly insists on saying goodbye to Topanga. Then Jack, who has been struggling to contain his own grief in deference to Shawn's feelings, falls apart and cries helplessly in Rachel's arms; and Eric walks in to find them kissing passionately.
