 " Halloween " marks the last appearance of Devon in an episode until the series finale , seven seasons later . Although Devon was only a background character , he is mentioned during " The Dundies " , seen in the background of " The Fire " , and is seen in a deleted scene during " Diversity Day " . Devon is later seen in a deleted scene on " Valentine 's Day " , when Michael passes by a homeless Devon in New York . Devon then chases Michael , presumably still angry over the events of " Halloween " . Guest stars in this episode included Devon Abner , Hugh Dane , George Gaus , Annabelle Kopack , Ava Nisbet and Alec Zbornak .
