Eric' cousin Penny, whom he used to tease unmercifully when they were younger, comes for a visit, and she's...grown some. All the guys are infatuated with her, much to Donna and Jackie's dismay. Jackie and Donna try to be hotter than Penny, with disasterous results. Kitty, feeling like she's not needed, wants to get a pet.
Eric is distraught after his break-up with Donna and wishes that they never kissed in the first place. As soon as he utters this wish, a guardian angel appears to teach Eric that it's better to have loved and lost than to have never loved at all. The angel takes Eric on a journey to the future -- the '80s -- to show him how everyone's lives would've turned out if he and Donna never got together. Eric remains unconvinced that the pain of his break-up was worth it, until the angel shows him all the wonderful memories he would have never had.
