TJ is a tricky character. Although he does not thrive on prejudice himself, he is happy to use it to his advantage. He is driven by his own need for acceptance and approval. This leads him to campaign against Mrs. Logan, not because she is ineffective as a teacher or dangerous in any way, but because she failed him twice in her class. He resents the grade and gets revenge on her to make himself feel better. What is ironic is that TJ's need for approval and acceptance is what causes him to be alienated. He has no loyalty, and so others do not trust him.

TJ would like to get Mrs. Logan in trouble because she supposedly gave him an F on his test on purpose.
