KC started stealing from the Mallrats in season 1, Lex feels that KC is just like him, and KC looks up to Lex as a role model [not good]. KC follows Lex around for a will, and soons started helping Jack with the windmill and they become friends. KC later doesn't look up to Lex, he is now his own person and does stuff for himself. KC gets into trouble one day with a tribe, and soon that tribe is all over the Mallrats, the Mallrats fight back, but can't. KC saves Lex's girl and Lex is happy for that, as Lex still feels responsilbe for him. In season 4 when Cloe gets back from when the chosen, KC get feelings for her, but Cloe isn't into that. KC later on gets take by the Techno's and we don't see him until season 5.
