Hyde (Danny Masterson) does his best to fit in with the Forman family. In fact, he does more than his best, and before long, Red (Kurtwood Smith) and Kitty (Debra Jo Rupp) are treating him as their own son -- much to the dismay of the jealous Eric (Topher Grace). In other developments, Mr. and Mrs. Forman are almost lured into a "ménage à quatre" involving Eric's war buddy Mitch and his wife, Joy (played by real-life husband and wife Mitch and Arlene Pileggi). And the marriage of Donna's (Laura Prepon) parents is in big, big, trouble. Those are the conditions that prevail as That '70s Show concludes its first season.
