It's Halloween and Betty is in for a series of frightful experiences, ranging from showing up dressed for the Mode costume contest . . . only to learn there isnt one, to dealing with her growing attraction to Henry -- while a jealous Walter fumes -- and, worst of all, tracking down a watch Daniel left at one of his many girlfriends apartments. Meanwhile, Daniel pays a visit to his mom in rehab, and Wilhelmina is horrified to learn that she can't fit into a designer gown.
