This episode marked Willie Aames' final appearance on the series. As he was at the peak of his popularity at the time, with his character featured prominently in most episodes, it remains a mystery why he was missing in action for three successive episodes. His absence also indicates that series personnel had no idea this was to be their last season, as one character is missing and five others barely figure in the plot. Had the creative staff known the show was not being renewed, they would likely have planned a more elaborate series finale.
Grant Goodeve doesn't appear in this episode, not even in the wedding rehearsal scene.
