S1, E5: It's Halloween and Betty is in for a series of frightful experiences, from showing up dressed for the `Mode' fancy-dress contest - only to learn there isn't 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 (he just can't remember which one). Meanwhile, Daniel pays a visit to his mother in rehab.
