Jon was sure he could get out of this, he just had to get to his stone once he got home.
Jen wasn't as sure. Jen had so much hair, and her cloths felt completely impractical though they were normal. Later, seeing herself in the mirror, Jen would say she had become the most beautiful girl she had ever seen. Jen would also find that her boyfriend liked the way she looked and dressed, and that she would blush when he would talk to her.
She may or may not have been left a stone though, she was after all, now a girl.
