This episode was intended to introduce Katie Rich as a recurring character named Cougar, a member of Denise's philosophy class. After becoming Cougar's study partner, Denise (Lisa Bonet) invites the girl to crash in her dorm room, on condition that she make herself scarce whenever dorm director Lettie appears. Unfortunately, the girl finds it impossible to be inconspicuous, and ends up getting Denise in plenty of trouble--especially when it is revealed that Cougar isn't even a registered student. Curiously, though Katie Rich makes an excellent impression in this episode, her character was never seen again. ~ Hal Erickson, Rovi
