Her dramatic moment, also with just one line, is coming onto stage just after her mother's funeral and then meeting her new stepmother.
"I have scared emotions and sad emotions," she said.
Winfield High School student Reiley Clark, 16, is the grown-up Cinderella.
She said she was surprised by the show's structure.
"I was also surprised that I got to be a brunette Cinderella," she added. An experienced actress, Clark said she finds it easy to learn lines - she has many more than the younger Cinderellas - especially with the help of her family.
Although her very favorite princesses from Disney stories are Belle from "Beauty and the Beast" and Pocahontas, Clark isn't complaining about this role, in which she gets to don an honest-to-goodness wedding gown.
"It's pretty legit," she said of the dress.
The show runs two hours and has a 15-minute intermission.
