Seeing this remarkably handsome and talented young actor on television again reminded how he first won my heart and admiration back in 2005 during the premiere episode of his eight season series run on “Weeds.” He was eighteen years old when the Showtime series began, adeptly and adorably playing intensely sexual Silas Botwin, the eldest son of housewife marijuana maven Nancy Botwin (the unflinching Mary-Louise Parker). Hunter Parrish started his guest appearance story arch on “The Good Wife” Sunday night.
