Played By: Brian Austin Green and Tori Spelling
The two characters begin the series dating in high school with David respecting Donna's decision to sustain from sex until marriage. The couple then break up after learning that David slept with someone, and their characters follow up the next few seasons with a strand of psychos, ending the seventh season with Donna finally losing her virginity to none other than David. Anyone could have predicted that David and Donna end up married by the series finale. And maybe we wouldn't have stopped caring about the couple if they were actually likeable.
