10. Blowups

Complete story — includes the ending

Part two of a two-hour episode. A terrible explosion at Dell's house lands Betsey and Heather in the hospital, and everyone is pushed to the limit trying to save their lives. Tensions rise even higher between Addison and the Captain when her mother, Bizzy ( JoBeth Williams ), shows up. Dell and Pete argue violently over whether Dell should let recovering Betsey visit her gravely burned and injured mother once more, knowing Heather caused the explosion. Addison walks in on Bizzy kissing a woman, Susan, who's been Bizzy's personal assistant for 20 years. Addison struggles to come to terms with both her mother's lesbianism and the realization that the Captain is not quite the scoundrel Addison assumed him to be. Heather dies of her injuries, portending consequences for both Betsey and Dell.
