While the war board grows cluttered with cases, a MacPherson-focused Artie has Pete, Myka and Claudia on inventory duty. Well, at least Myka is doing inventory. Pete is playing ping-pong against his own reflection in Lewis Carroll's mirror. But when a moment of teasing between Myka and Pete turns into an explosion of light and rhythmic beats as the Studio 54 disco ball tumbles down and the mirror topples, threatening to crush Myka, Artie decides it's time to assign them a case! Pete and Myka are dispatched to Las Vegas where two small-time thieves - Gary and Jillian Whitman - continue their unusual winning streak.
