The episode starts with the tweenagers (Chuckie is a practical teenager, kind of) searching in the basment for halloween costumes at the Finsters. Then after Lil removes a box, they find TP+KF carved. Both Tommy and Kimi quickly deny this statment, as Tommy is snobby and tells Kimi to "Tell Chuckie I have no interest in you" and Kimi eventually does. Later, Chuckie gets supscious when Tommy goes to meet Kimi about something (Not knowing they were talking about him) but uneventually they break there friendship. Then later, Tommy and Chuckie still refuse to apoligize to anyone, but Kimi hatches a plan. The tweenagers eventually trick Tommy and Chuckie into going into the same Reptar costume but after they break the costume apart Kimi admits she liked Tommy when she was nine (And shows at the end of the episode she still does).
