The last episode of Showtime's long-running show about suddenly widowed suburban mom Nancy Botwin (Mary-Louise Parker), who must turn to selling marijuana to make ends meet, tried to do quite a lot in its final episode. Things got pretty jumbled, as the show attempted to resolve most every loose end (but not all of them), show what happened to most every character (but not all of them), and give everyone a happy ending, with a sudden time jump a few years into the future.
By that point, marijuana is legal, and Nancy and her business partner/son Silas (Hunter Parrish) have apparently gone legit, with several successful marijuana-based business endeavors. (The show could've actually shown Nancy and Silas growing their business, but instead just says it happened.) Nancy's once-little son Stevie is now 13 and preparing for his bar mitzvah. (Nancy's last husband, a rabbi named David, died offscreen in a car crash.) The orphaned son of one of Nancy's other husbands, Tim, once tried to kill her, but now he's working for Nancy as her business manager, so it would seem they patched things up. Celia (Elizabeth Perkins), a main character in the early years of the show (Elizabeth Perkins) isn't mentioned at all, but her husband Dean (Andy Milder) is around, and mentions that their daughter transitioned from female to male. Shane Botwin (Alexander Gould) is an unhinged cop. Andy Botwin (Justin Kirk) hasn't spoken to Nancy in years, but comes home and mentions he has a daughter.
At the end, most of the main characters all smoke a joint together, and they agree to sell much of their business to Starbucks. As they sit in the snow, smoking, Nancy and others laugh. Why? Because she's finally free of marijuana and all its entanglements that severely messed up her family life.
