George does not understand if he is doing anything wrong, but his mother suspects something is wrong with him.
While at school, George hates using boys' toilets and feels he should use girls' washrooms. George's mother later realizes that George is transgender and he is more girlish than boyish. In "Charlotte," George asks Ms. Udell to allow her to act as a female character in the play. Jeff and Rick start laughing and teasing George that he should not be playing girlish roles in the play, and this ridicule makes him cry. However, Kelly comforts her and tells her that it is good she is coming out boldly to claim her identity as a transgender person.

Melissa has female friends in the magazine. George wishes he could have more female friends because he is more feminine. Melissa makes George hope to be a girl and not be perceived as a boy because she hates that feeling.
Scott
Scott is George's brother and always tries to investigate why George is so secretive. One day, Scott suspects that George is hiding in the bathroom, and he bangs the door and enters.

Kelly
Kelly is a close friend of George, and she always comforts him and encourages him to come out openly and admit that he is a girl instead of suffering in silence.
