Buffy the Vampire Slayer's first two seasons had established the modus operandi of unveiling a new villain and fresh overriding concept as each season began. The Slayer's senior year at Sunnydale High was no different; themes of power, corruption, and betrayal were encapsulated in the introduction of two new characters. Scheming to achieve supernatural transcendence atop the Hellmouth, crooked Mayor Richard Wilkins III (Harry Groener) served as the season's cuddly but creepy "big bad." But it was Faith (Eliza Dushku), Buffy's new fellow slayer and eventual dark foil, whose descent into sadistic villainy packed the bigger emotional wallop. Of course, as the season began, Buffy (Sarah Michelle Gellar) was still smarting from the last time a trusted ally had turned on her. But the mysterious return of Angel (David Boreanaz) from the hell to which Buffy had dispatched him caused as many problems as it solved. (Eventually, as the season ended, Angel would leave Sunnydale for the larger horizons of Los Angeles in an eponymous spin-off that lasted five seasons.) As for the other characters, romantic entanglements continued between Willow (Alyson Hannigan), Xander (Nicholas Brendon), Cordelia (Charisma Carpenter), and Oz (Seth Green). Giles (Anthony Stewart Head) and Buffy's mother (Kristine Sutherland) even enjoyed a brief dalliance while under the influence of an enchantment. Fledgling witch Willow continued to hone her own magical talents. Xander lost his virginity -- and nearly his life -- to Faith. Stuffy new arrival Wesley Wyndam-Price (Alexis Denisof) usurped Giles' role as Watcher, allowing Buffy's mentor to exhibit a newfound suaveness and cynicism. And longtime bit player Jonathan (Danny Strong) took center stage in the controversial episode titled "Earshot." Penned by new staff writer Jane Espenson, whose gift for comedy had already made a big impact with fans, the otherwise humorous episode marked one of the first times a gun had figured prominently in a Buffy plot. In deference to the Columbine High School massacre in Littleton, CO, the WB delayed airing "Earshot" -- and the violent season finale -- until months after they were originally scheduled. Nevertheless, the third season's final arc effectively brought the show's long-running high-school-is-hell conceit to its logical conclusion.
