Eric conceals his struggles with math from Red, hoping to demonstrate his commitment to his future. Impressed by his son's newfound responsibility, Red promotes Eric to the adult table at Thanksgiving, displacing Laurie. This gives Eric the confidence to consider revealing his engagement to Donna. However, the arrival of Kelso's date at the Formans' dinner throws a wrench into his plans, making him hesitant about the timing of his big announcement.
