Donna's dad and his partner Joanne are off for a weekend getaway, so Eric and Donna plan a weekend together to prove to themselves that they're adult enough to be engaged. The gang is determined to throw a party at Donna's, and are unforgiving when Donna refuses. Meanwhile, a call from the jeweler makes Kitty think Red is buying her a present, but she finds out the ring is from Eric to Donna while taking 'poor orphan' Hyde shopping for a new coat, which Hyde hates--an Evis-style flashy jacket that looks nothing like Hyde's style. Kitty tries to prevent Red from finding out about the engagement, but Eric lets it slip in anger during one of Red's tirades. The cat's outta the bag--Donna and Eric's engagement is no longer secret.
