Returns: Monday, April 7, at 9:30 pm/ET (ABC) Number of new episodes: 6 Where we left off: Amnesia-addled Samantha (Christina Applegate) continued to learn about her past: restraining orders = bad; sex = good. What's next: Sam may have finally gotten over studly carpenter Kevin (Eddie Cibrian), but her relationship woes have only just begun. "She'll have to choose between dating [old flame] Todd and marrying her super-rich boss," executive producer Don Todd teases. Occupational hazards: Fending off the advances of her boss (Timothy Olyphant) isn't the only thing she'll contend with at work. When Sam protests a controversial company decision by lying down in front of a bulldozer, she starts to realize that a career switch might be in order.
