Tommy Ross dated Sue Snell for six months at the beginning of the novel and began to have sex with her four months later. He loved her and decided to go to the prom with Carrie out of love for her. He appreciated her company and was with her, when they appointed both of them Prom King and Queen. When they both went into the corresponding chairs, they both became victims of the same prank, but with a difference. The empty bucket above Tommy then fell on Tommy´s head killing him and Carrie felt his death telepathically. This, together with her own humiliation, ignited her hellish quest of revenge later, after she went away from the gym, while everyone was laughing, including Miss Desjardin.

The Black Prom was the result.
