That ’90s Show season 2 has left a big That ’70s Show question a mystery, and it’s likely that audiences will never get the answers they are looking for. The Netflix spinoff did a great job overall filling in the details of what has happened to the That ’70s Show gang since the series concluded. This is especially true for season 1, which brought back most of the original cast for cameos. However, That ’90s Show has pushed the story forward, focusing less on the previous series and more on the new group of 1990s-era teenagers, hinting that questions about one original character won’t be answered.
