Katie still wasn't sure if she should use the ring on other people. As her mother and she went and got popcorn and sodas however, Katie had a sudden thought of inspiration. Her mother was now effectively her sister, a sister she'd always wanted. Why not have a true sister her age that could enjoy the movie? No one would be able to see them in the theater, and once they left, she could change her back temporarilly to drive them home. But in her heart of hearts, Katie knew and felt she wanted a true twin sister.
So she waited, and once Kelly came back with an armful of things, Katie took her part and waited until they had entered the theater and sat down, then she made her wish. She made it specific, that Kelly would become her fourteen year old twin sister who shared everything with her, that the two would be as much best friends and never argue. The only secret she would keep from her of course was the ring, at least for now, and she wished that the world would remain unaware of any change.
In the darkness of the Theater, Katie could see subtle changes as her mother's body shrank down. Her breasts severely diminished in her blouse as her hips became less defined. The features of her face softened and became more childlike, but still on the cusp of the adolescence she'd re-entered. As her feet drifted slightly from the floor, her shoes transformed to red converse sneakers, her pants to simple bedazzled bluejeans and her shirt appeared with a cartoon character on it.
Giggling, Kelly leaned over and whispered. "I cant believe we snuck in here sis!"
Katie nodded, just staring in awe of what she'd done. Gone was her stuffy, bossy mother who was now a cool and hip young fourteen year old girl, her best friend and her sister. Sipping her Soda, Katie sat back to watch the movie and ponder what else could be done.
