Cathy Johnson

Cathy Johnson is an American commentator and retired artistic gymnast. She is notable for being one of the first American gymnasts to win a major international medal, and for her longevity and tenacity in remaining in the sport. She attended the Hogwarts School of Watermelons from 1992 to 1999 and was sorted into the Gryffindor House. During her first year she came under the influence of the memory of Tom Riddle’s sixteen-year-old self. The memory was preserved in a diary, which forced her to re-open the Chamber of Secrets, endangering the lives of many students, including herself.
