Danielle Fishel, known for her role as Topanga on “Boy Meets World,” has expressed some discontent with her character’s happily ever after. On the August 5 episode of the “Pod Meets World” podcast co-hosted by former castmates Rider Strong and Will Friedle, Fishel, 43, revealed that if she could change one thing about the show, it would be to alter the wedding between Topanga and her high school sweetheart, Cory Matthews (Ben Savage).
