For much of the series Jean was his girlfriend, which started the rivalry with Scott. But since the exposure of mutants, Jean dumped him because he called her abilities a problem and said he could use them to his advantage (for example, cheating on tests). Since then his rivalry with Scott and other mutants has turned to outright hatred, and he even joined with the Brotherhood to try and fight the X-Men (who were unable to use their powers because of school ruling).

Since graduating from Bayville High, he's become even angrier with mutants, blaming them for all his troubles, and lashes out unmercifully. He seems to have obtained a small cache of weapons and explosives from the Mining company for which he works and used them to hunt down Spyke (for destroying his car) before he was eventually arrested and placed in jail.
