Gillespie has to finally choose his official assistant, or Red and Lee are going to kill themselves in competition. So, it's another diagnosis competition. Lee's assignment is a small girl who falls ill whenever she eats candy. Red has to cure a girl's mother of a debilitating case of arthritis. But when Red needs Lee's help, will either one live with Gillespie's choice?
