The decade-long friendship between Cory (Ben Savage) and Shawn (Rider Strong) may be at an end when Cory thinks about attending a different college than Shawn. This leads to an extended flashback to the boys' childhood--which is somehow invaded by a young Topanga (played by Danielle Fishel lookalike Rosario Gru). Meanwhile, Eric (Will Friedle) and Jack (Matthew Lawrence) are convinced that college life will be a breeze if only they can become close friends with Dean Borak (Paul Gleason). ~ Hal Erickson, Rovi
